Liquid Electrical Tape - brush on insulation
With the high price of coaxial cable and antennas can you afford not protect your investment with this great product? Dries in minutes and is impervious to water.
Stocked in response to customer demand!

If any of you are thinking about getting some liquid tape off Richard.... Do so!! I can only say 'it's superb!'...
FAST AND PERMANENT REPAIRS ON WIRES AND CONNECTIONS AND MORE...!
Liquid Electrical Tape is an air-dried, synthetic rubber coating that can be brushed on and exhibits excellent moisture, acid, alkaline, abrasion, and dielectric resistance.
Offers far more efficient sealing than sticky cable seals and tape. Perfect for quick access and portability! Great for sealing all antenna connections. The coating is flexible making it ideal for use on portable antenna connections. Tests we have done show that the product, unlike many other sealants, does not affect the Q of toroids used at HF - it has good dielectric properties and low losses.
Liquid Electrical Tape remains flexible even under extreme conditions and won't crack, harden, or peel.
Electrically insulates to over 1380volts/ml.
Liquid Electrical Tape is excellent for use in a variety of applications including electrical connections and components for boats, trailers, cars and lorries, timers, outdoor wiring, instruments, computers, circuit boards, switches, radio antennas, and many more. Easily removed from non-porous surfaces.
Supplied in a 4 fl.oz (118ml) container, with applicator brush mounted in the lid. Colour - Black. One can contains enough Liquid Tape for dozens of connections.
Use on Aerials
Have you ever felt that your aerial system is not performing quite as well as it used to? Maybe the beacons are just a little weaker or the DX is that much more difficult to work? One common reason for such observations is getting water inside your feeder cable. Rainwater will leak in wherever it can and few sealing methods offer good long-term protection. The design of coaxial cable is such that it draws water in by capillary action. The water can then corrode the wires inside the coax, it also degrades the dielectric performance - increasing losses - sometimes dramatically. Meanwhile back in the shack often all appears well. Increased cable losses make the SWR of aerials look better, but your power is not being radiated, it's heating up the inside of your damp cable. As often as not, water ingress goes un-noticed until water drips out of the cable inside your shack. In the meantime you have been using a radio system that has been below par for months or even years.
Liquid Tape is the answer! This product is easily painted onto all types of electrical joints using the brush applicator within the can. It dries in just a few minutes leaving a low-loss, flexible and impervious coating on your cable. No more water ingress! A single 118ml can contains enough of the product for dozens of connections!
Liquid Electrical Tape is potentially harmful to health. It must be used only as indicated on the pack. Wear impervious gloves and eye protection when using this product. Use in a well ventilated area. Store away from children. Download the product safety data sheet here.
Once fully dry, no special handing or precautions are required.

Requires a re-coat to get a good thickness of insulation, but generally seems to be a good product. Yet to see if it keeps out rain, as we have had little rainfall in the south.
Excellent sealant and perhaps most important - the same dielectrical characteristics as air so it will not detune your design when weatherproofing it.
I used the liquid tape to waterproof I recently purchased Sotabeam trap kits for a 3 band vertical antenna project. Not only was it easy to apply on the traps, but very importantly it didn't detune them. Also used the liquid tape for sealing the connection box and coax connections. Ideal!!
As they say,you get what you pay for.
Easy to apply with supplied brush,and lasts longer if kept in a cool place.Recommended.
This is an excellent product at a good price. It has many uses both in and out of the shack. I use it for fixing toroid s etc to a pcb and outside it's great for sealing coaxial connections.
It is paramount that the instructions are followed with regard to safety, it must be applied in a well ventilated area.
Great product and great service. Couldn't ask for more.
This felt like a bit of an extravagance when I bought it to seal the end of a coax...but how useful it's been.
Basically if you build aerials you'll love this stuff. I use it to seal the ends of my coax and any external joints along with traps and, maybe weirdly, baluns. I even use it to seal the numerous leaks in the roof of my Land Rover!

Does what it says on the bottle. Don't forget the warnings though, wear impervious gloves and make sure that you don't inhale the gas that is given off as it dries.
I used it with the HF Traps and it seems to be just what is needed.
