Electrical Tape assistance by using okØFF
Did you ever note that electrical tape, like a hammer, comes with out a directions? in all probability the makers figure that everybody immediately is aware of all the "hints of the alternate". examine on, you can also decide upon up a new wrinkle.
Vinyl electrical tape has been round seeing that 1945, however for a long time after it was introduced, black cotton friction tape became nevertheless used for most applications, partly because of the cost difference, partly on account of culture. I be aware tearing long strips of half-inch friction tape into quarter-inch wide strips as a cost mark downs. a distinct characteristic of the adhesive on the friction tape is that it offers off an eerie blue gentle when the tape is peeled from the roll. it's vibrant adequate to be with ease considered in a darkened room. aside from that trivial truth trendy friction tape is used for special purposes only as a topcoat for mild rubber tape as used on high voltage cable spices. modern materials are superior in each respect. the first vinyl tape I ever noticed on the job become gray in colour, no longer black, I believe it changed into a cellphone enterprise spec.
nowadays i like to recommend the usage of most effective Scotch 33+ tape for all ham radio makes use of, apart from as stated at the conclusion, because it has predictable qualities and is respectable for every indoor/outside utility. The temperature latitude is zero F to 220 F.
be sure to get the class with the + signal, as there is also a undeniable type 33.
3M also makes product known as Temflex, but again category 33+ is correct for each application, specifically outdoors.
When taping over coax connectors, or coax splice kits, it is helpful to first wrap the connector with a self-amalgamating Silicone Tape product. The 3M edition is category 70, and Radio Shack also sells it in small rolls below the part number 64-2336.
here's now not the equal product because the coax-seal, or Radio Shack #278-1645 "sealant for RF connectors". I don't take care of that sticky material, dum-dum, or any other putty class material it truly is difficult to eradicate later. The silicone-tape peels off cleanly and easily, so effectively in fact that it has to be coated with a topcoat of classification 33+ to offer protection to it. This two layer strategy, when applied as defined beneath will provide a waterproof seal this is climate resistant, and stays flexible for years, but can effectively be eliminated if alterations need to be finished to the device.
Any time you wrap tape on a threaded component, be certain you wrap it within the path that tends to tighten the screw threads, not the wrong way. That means if you're taping a splice, as an example two PL-259's screwed into a double barrel female (PL-258/83-1J) you ought to tape each connector from the cable end to the barrel middle.
at all times run the tape "uphill" this is from the smaller diameter to the bigger diameter.
beginning at the smallest end, make a number of tight turns of one-quarter lap for a pretty good seal, then run the tape in one-half laps to the center, with moderate stretch so the diameter of the 33+ is reduced to about five-eighths of it be fashioned width. On the closing few turns reduce the stretch tension until it's zero at the final flip, to keep away from flagging. Use a scissors to reduce the tape conclusion rectangular, as a knife or ripping will add stretch to the ultimate lap and cause it to return unfastened. Repeat the identical strategy from the other facet, and meet within the middle (if it is a splice package), overlap the left hand aspect tape with the appropriate hand aspect tape. If the connection is to be removed at a comparatively short timeframe, fold the final hat doesn't stick. If the tape job is everlasting, without difficulty lay the closing lap down flush. Now for the surest-stored secret, spray the entire assembly with clear coat enamel or other dielectric spray. i exploit Krylon Crystal Clear. The over-spray completely seals the joint and keeps the ends flat.
Non-electrical makes use of for electrical tape.
For taping cables to tower legs and different such jobs, accept as true with using the Temflex or straight type 33 as they each are less expensive and have a slightly higher breaking electricity. The superior conformal qualities of the 33+ are not mandatory in these purposes.
one of the crucial average non electrical makes use of of vinyl tape is to secure rolls of wire, bundles of tubing, cables to rungs, and a lot of other unusual jobs that use the material for other than it's weatherproof or electrical characteristics. To tie up a roll of cable, the most cost-effective grade of black vinyl tape is sufficient, except that it leaves a gooey mess behind when eliminated. the secret right here is to make the first full two turns with the sticky aspect OUT. Then conveniently twist the tape round on itself and continue making a few extra turns with the sticky side IN. This same trick can also be used with cellophane tape to cozy ironmongery store bundles of conduit, pipe etc, in order that it removes cleanly. hope I had a nickel for each minute wasted trying to get that sticky mess off copper water pipe before soldering!
one more slick conception Scotch came up with is the colour-coded vinyl tape. I've tried many schemes through the years of using red, blue, green white and other color tapes to identify definite cables, as an instance coax cables in a bundle run up the tower. After toughly complicated myself, I decided to comfortably use the white tape, and mark the identity on it with a Sharpie permanent marker. Foolproof, and lasts for years.
A remaining observe, the greater tapes like 33+ have a shelf lifestyles score of 5 years, however nonetheless be cautious of "surplus finds", as the age and storage circumstances are doubtful. most effective to purchase fresh tape from a favourite, trusted source.Member comments: this text has expired.

As an delivered notice, i'd also want to point out that after leaving the final turn of electrical tape for your coax make sure you at ease it with an ultra violet resistant (black) tie wrap. This prevents the tape from unwinding itself from publicity to the points, exceptionally if your using low priced tape.   Electrical Tape advice with the aid of okØFF by KA0OXH on April eleven, 2003 Mail this to a chum! extraordinary article from George. i want to add a few of my experiences which have been exceeded right down to me in my travels.
I started out within the radio gig about 22 years ago as a tower hand for the native Motorola provider now as a Senior RF Engineer for a instant provider. nevertheless play HAM radio since day one... things I have used and my feedback:
Scotch 33+ is tremendous but you deserve to stretch it as you observe it to get the maximum adhesion. I even have found Scotch 88 has more suitable bloodless climate characterisics.
Weatherproofing compounds equivalent to "Butyl rubber", "Vapor Wrap", "Andrew weather proofing kits" "Scotch Kote" and so forth work neatly but are very messy. I have tower crews now that at all times put a layer of tape under the weather proofing. This observe could cause your vapor bloc to fail and condensation to form in the coax connector.
i love to make use of the self vulcanizing tape or vinyl mastic tape. 3M Scotch sells all it below different names, similar to "scotch 23 tape","vinyl mastic tape" or "electical insulation putty" tape. if you practice this stretch it identical to you had been taping the connector and that i all the time observe it up with a couple wraps of 33+ or 88 tape which each Ham operator may still have as commonplace tape! Makes an ideal vapor bloc to the connector if applied effectively. now not messy at all!
73's maintain the water out of these connectors.
Dan KA0OXH  RE: Electrical Tape suggestions by using okØFF by means of W0FM on April eleven, 2003 Mail this to a pal! first-class article and top notch counsel, George. pleased there's someone inclined to to tackle the "sticky" topics.
73 de Terry, WØFM  RE: Electrical Tape counsel with the aid of okayØFF via WA9SVD on April eleven, 2003 Mail this to a pal! decent article, but one remark (from a friend formerly in the army...)
When wrapping with tape, equivalent to a barrel connector and two coax connectors, delivery at the center of the connection, wrap the tape in one route (with a generous overlap) the use of reasonable tension, until about four-6 inches past the connector. Then reverse course, once more with tension until 4-6 inches previous the different connector. Then reverse path, once again below tension, until you're lower back on the core, after which a few turns without anxiety so the tape doesn't birth to unwind over time. This offers you two layers of tape for further insurance plan, and no uncovered "birth or cease" elements that may go away tiny gaps for moisture entry. I (individually) additionally use a blact tie wrap on the uncovered conclusion to keep it from unwrapping. The formula works for me, however your mileage (or opinion) can also differ. respectable good fortune to all.  Electrical Tape guidance via kØFF by way of KD5ING on April 11, 2003 Mail this to a pal! here is superb stuff. simply the form of "elmering" us new kids want! Thanks for the outstanding article!   Electrical Tape counsel with the aid of okayØFF by means of W3DCG on April 11, 2003 Mail this to a chum! thank you! exactly the query on my mind lately... I have the beads on my RF choke "Balun" all placed (did that ultimate evening) and am now taking into consideration the splice i may must make on the way to also be found inside my 1" PVC conclusion-capped housing. I feel like this article become written for me! Thanks once more.   RE: Electrical Tape suggestions by using okayØFF through WB2WIK on April eleven, 2003 Mail this to a friend! great article!
it will be decent to factor out, although, that stretching vinyl tape like Scotch 33+ (or an identical) while wrapping *coaxial cable* may also be a very dangerous thought, certainly if one is taping the cable to something hard and unyielding like an antenna increase, antenna mast or tower leg.
reason: Coaxial cable, or lots of the cables we hams use, is tender and never rated for any compression energy at all. Stretching vinyl tape while wrapping, mainly when making overlapping layers of such stretched tape, can region lots of of pounds per rectangular inch of compression drive on the cable -- now not good. may be for hardline, Heliax(TM), and a few very strong cables corresponding to RG217/U, RG17/U, RG18/U, and so forth -- however a really bad theory for "RG8" type cables, including all of the cellular poly dielectric ("foam"). that you could just about squash them flat with compression, changing their attribute impedance at the taping factor, and in lots of situations inflicting everlasting, irreparable hurt to the cable.
virtually each time I've considered "RG8" cables fail all the way through better energy operation, the failure has been a dielectric breakdown (inflicting a short circuit between core and outer cable conductors) occuring exactly at a "taping" aspect.
WB2WIK/6  Electrical Tape tips by using okayØFF by way of NA2A on April 11, 2003 Mail this to a chum! One other hint--when completing the wrap go away short length not taped to cable. Fold small component returned towards itself to kind a tab for gripping to ease unwinding tape.   RE: Electrical Tape counsel by using kØFF with the aid of KE4SKY on April eleven, 2003 Mail this to a friend! All super stuff! Thanks everybody.
I've gotten into the addiction of portray a layer of West Marine "Liquid Electrical Tape" over over the vinyl tape to keep it from unravelling in the wind. It additionally discourges birds and squirrels from fooling with the unfastened end, by using combating it from coming unfastened within the first area!
I additionally use the tape as additional UV coverage over cable ties on towers, as even the black ones turn into brittle with time, and a tape UV defensive layer layer liberally sealed on the conclusion with Liquid Electrical Tape will stand up to direct run, wind and rain for years.  Electrical Tape suggestions by using kØFF via W8OB on April 11, 2003 Mail this to a chum! do not forget a couple of basic suggestions from one who makes use of miles of 33+ and 88+. when you've got a tight spot to tape guessimate the volume of tape mandatory, roll out the size cut it with a pointy knife and roll it lower back onto itself (sticky aspect up) the that you would be able to wrap across the tight spot and unwind the tape similar to a ace bandage. certainly not stretch and pull the tape to destroy it free from the roll, use a pointy knife this prevents flagging of the tape. in case you live in a chilly local weather analyze using 88+. For taping coaxial connectors I all the time finish the job with a coating of scotchkote over the tape. throughout the years I have realized under no circumstances to splice coaxial cables outside with a barrel connector, it has gotten so cold up here that from time to time trust it or not the barrel will contract enough to free contact with the middle of the pl-259 plugs. i use appropriate coax splicing devoid of fittings and have yet to be aware any alterations in VSWR on the antennas. Of route these jobs are always accomplished with first rate old scotch manufacturer electrical tape.   Electrical Tape information by using okayØFF via KZ9G on April 11, 2003 Mail this to a pal! high-quality Article.
or not it's superb that you simply outlined the use of Scotch 70 self-fusing rubber tape for the primary, weatherproofing layer. i have been the use of Scotch 70 for a couple of years - it really works wonderfully and is removed effortlessly (splits) when a knife's facet is run alongside the taped joint. skip the other gooey methods and go the Scotch 70 route. I also liked WB2WIK's comment on cutting back the wrap compression when the use of electrical tape to affix cable to tower legs, and so forth. We may still all deal with our flexible RF cables with care - in particular if high power is employed. 73 - Steve, KZ9G  Electrical Tape suggestions with the aid of okayØFF by means of K5MAR on April 12, 2003 Mail this to a chum! "Any time you wrap tape on a threaded element, be certain you wrap it within the course that tends to tighten the screw threads, not the wrong way.

Sorry, however this is simply in need of clear (to me, at least). It appear to me that the essential ingredient in the above is the path you are taping in, clockwise or counterclockwise, not the system of taping from smaller to bigger. So, searching down on a PL-259 related to an SO-239 on an antenna, do you tape in a clockwise or counterclockwise direction? i might say clockwise, but can feel of arguments for both path.
apart from that, thanks for the advice!
Mark Schneider K5MAR  Electrical Tape tips by means of okayØFF via KG4WBH on April 14, 2003 Mail this to a friend! hi there all and sundry, needed to put my 2 cents in...... I actually have been doing industrial electrical for round 15 years now and that i have used loads of electrical tape through the years. The feedback in regards to the rubber tape are respectable, I simply desired so as to add one thing to them. To get the "gooey" tape free if you want it off, just wrap the connection with the vinyl tape sticky facet out simply tight sufficient to preserve it from slipping, then put the rubber to it. This makes removal of the rubber tape later an easy count (for the reason that you should cut it off anyway, just be careful and dont cut your coax.). also, I feel clockwise would be the direction of shuttle on the connector....:)   RE: Electrical Tape counsel with the aid of kØFF via W9DZ on April 15, 2003 Mail this to a pal! WB2WIK made an outstanding aspect. Too much wrap pressure will distort the 9913 category cables causing an impedance bump. I feel this became mentioned in QST (recommendations 'N Kinks?) a long time in the past.   RE: Electrical Tape guidance by okayØFF via AC6DN on April sixteen, 2003 Mail this to a chum! If u best hand tighten pl-259's (and different rf connectors), then with temperature adjustments, they can come loose. i like to recommend that, they be tightened with pliers. Don’t over tighten, though…   Electrical Tape advice by way of okØFF via WZ8S on April 16, 2003 Mail this to a chum! WOW- good day can't agree with SOMTHING SO easy CAN HAVE A right means OR dangerous way , but YOU MADE SOME VERY good advice. THANKS -TOM   RE: Electrical Tape assistance by using kØFF through N5REL on April 20, 2003 Mail this to a friend! Scotchwrap 50 is a superb all-climate tape/wrap which i might recommend layering over a tape-job using 33 or 88. especially in those crucial applications...like on the connector of the repeater antenna's pigtail 300' off the floor!
50 is wider (2") than 33 or 88 (which is usually 3/4" huge). The added width makes it superior for moisture resistance as a result of the capillary impact.
50 goes for roughly $14 a roll. 33 / 88 is ready $four. (I work for an electrical give business - - a 3M distributor)
73, Nathan N5REL  Electrical Tape suggestions via kØFF through KC0LPV on November 25, 2003 Mail this to a friend! decent article, and first rate guidelines!
whereas I respect that tearing tape is not the favored formulation, it is now and again easy (notably in short-repair or emergency instances) to be able to tear lengths of electrical tape while one in every of your arms is occupied.
I take a daily razor blade and make four incisions in the aspect of a roll of tape, a millimeter or two deep. This makes common 'nicks' within the tape at about 2-three" lengths. just unrolling the tape or wrapping a cable, the nics are unnoticeable. but for those who go to tear off a bit, you just discover a nick along with your fingers, and tear there. It is rarely perfect, nevertheless it's a a good deal cleaner 'cut line' than simply pulling the tape unless it breaks.
Jim kc0lpv  Electrical Tape counsel by okayØFF via N0RTU on December 31, 2003 Mail this to a pal! Greetings all! There are some top notch counsel posted here related to using electrical tape. youngsters, lets do not forget that in a pinch, this same tape will also be used for a lot of things. As an electrical vigor lineman, I've considered " tape" used for many issues. 1. have you ever had a radiator hose bulge or break up, leaving you stranded along the highway? allow the offending vehicle to cool and wrap the split hose profusely with 33+ and refill that radiator with water from a nearby pond or creek. you are back on the highway. I've had this restore last as much as 50 miles. enough for most of us to get to aid. (Flush your cooling system fully after this trick as pond water might also now not be the top-quality on your aluminum radiator!)
2. Scotch brand 33+ makes a dandy "rope" or tie down strap in a pinch. I've hauled a 2in. X 12 toes. aluminum pipe (for my gin pole) on the bags rack of my mini van greater than 1 time by using liberally taping stated pipe to the rack. You do not believe here is clever? are attempting taping some thing on in this method and use as a minimum half to 3 quarters of a roll. you will tear the bags rack off of the roof before you're going to pull the pipe free from the tape! (i'm now not advising that tape be substituted for rope or tie down straps on an everyday basis here. only when the applicable tie downs are not accessible and a cut price that is simply too decent to let go by using appears!)
three. In an emergency, tape may also be used to grasp a splint in location on a broken arm or leg. (be sure you don't wrap observed arm or leg too tightly otherwise you will bring to an end circulation and create a larger issue than the damaged arm turned into to birth with!)
four. despite the fact some will flinch at this.......I've used tape as a makeshift "bandaid" on unhealthy cuts unless I might get to a primary aid kit or other clinical aid.
There are a number of other uses for electrical tape. despite the fact, i am bound the moderators of this discussion board would now not appreciate me posting these right here at present. Suffice it to assert, Linemen can be rather wonderful and inventive when it comes to the use of "33".(Let your creativeness run wild here.....)
73 to all Mike N0RTU  Electrical Tape information with the aid of okØFF via NEVTXJUSTIN on March 31, 2005 Mail this to a chum! your entire suggestions are very good, besides the fact that children i spotted the want to have a "re-enterable" tape job which would be alluring for ham operators, however industrial purposes will usually demand a "permanent" seal.
When i was part of a mobile enterprise’s GSM rollout, I had to re-enter over 300 connectors in a 2 month length and reseal them. I did a "courtesy wrap" of Scotch 33 or equivalent as the first layer to evade the self-fusing mastic (self-fusing is more appropriate than "self-vulcanizing" as no heat is worried for real vulcanization of the rubber) from pretty a whole lot permanently adhering to the coax connectors. This changed into adopted with a mastic construct up to resemble the aspect view of a football. next became a layer of two in. vast tape to compress and kind the mastic down tight. The closing wrap changed into of Scotch 33 for waterproofing.
The coax runs had been tagged with strips of colored tape which gave the impression to have held up for a number of years, chiefly if the final inch of the tape become cut and applied with minimal stretching.
Having been doing tape jobs for over 30 years on communications towers, i will be able to say that “Scotch Kote” best lasts a yr or so earlier than sunlight decomposes it. As for the Liquid Tape, I don’t understand; but to date after 3 years it appears to be like new.
As for the climate and daylight resistance of black wire ties…they'll at last fail after several years, however nevertheless plenty longer than one Texas summer of the white nylon classification.
As for emergency clinical makes use of…Oh yeah! I nipped the ends of fingers essentially completely off a few times. Black tape and a paper tower – no longer even a scar five years later.  Electrical Tape tips through kØFF through K1CRA on July 23, 2005 Mail this to a chum! extraordinary article however I (with intent) stay mystified as to why so many continue to be dedicated to electrical tape (or coax-seal or silicone)to water-resistant connectors.

It dries fast and in fact varieties to every feature of the cable and connector by using shrinking as it dries and preventing any possible water infiltration. It waterproofs so neatly cables can also be run underground or underwater. Plus, it is much more flexible than tape and provides electricity to the joint. When able to eradicate, simply score it with it sharp blade and it peels off, usually in a single piece. And, as an delivered bonus... it cleans the connector when it comes off too! i do know, historic ways are complicated to change however, trade is respectable! seventy three! Craig - K1CRA   RE: Electrical Tape suggestions via okayØFF via KB9WIS on June 27, 2007 Mail this to a chum! Let me ask this, which tape is the "stickiest" or have the most appropriate adhesive residences, yet has first rate exteme temperature and climate resistant houses?

i would like to use a good tape for this, versus permanently bonding them along side a glue.. become the use of electrical tape, but sizzling summer season days tends to trigger the tape to birth to slide.., which adjustments the actual and electrial lengths of the wire vertical connected to it..
