G-QRP Reflector - 18 August 2007

If any of you are thinking about getting some liquid tape off Richard.... Do so!!  I can only say 'it's superb!'...

Ian, G3ROO


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.


Once fully dry, no special handing or precautions are required

  1. Fantastic service / Fantastic Product

    Posted by Clive on 24th Mar 2014

    Where do I start.
    Ordered yesterday and arrived today. Fantastic shipping time.
    The liquid tape is a real good product, it is the first time that I have used it, but it will not be the last. I sealed the joints and control boxes, and all connections on my antennas. They have all stayed bone dry and I have had no problems.

    Richard, thanks a lot for excellent service from you, it can not be improved on.

  2. Good

    Posted by Hannu Virtanen OH6HLH on 26th Dec 2013

    Excellent antenna installation, weather resistance, I do not know.

  3. Liquid Electrical Tape

    Posted by TERRY SAYNER on 24th Nov 2013

    This is my 2nd time I have ordered this product and is very good I use it on all jobs to be coated that would be open to the elements and is better to use than the amalgamating tape.

  4. So versatile!

    Posted by Dave G4AKC on 4th Oct 2013

    This is my second tin of "Liquid Electrical Tape", I operate on the beach in Blackpool and so I need all my terminal connections protected against the salt corrosion.
    This is the ONLY product that works as it coats all of the terminals against exposure to the air very effectively.
    I have used self amalgamating rubber tape in the past, but there are always small gaps and it is also difficult to adhere it to small terminals, whereas this product covers the smallest of terminals perfectly.
    In a nutshell, I highly recommend this product and whats more its cheaper from Richard than anywhere else!

  5. Liquid Tape

    Posted by Martin on 29th Aug 2013

    Very good product with excellent service from Sotabeams, good price with reasonable postage. Would buy again from Sotabeams in the future when I need more. Thank you.

  6. Liquid tape

    Posted by Unknown on 11th Aug 2013

    First of all I would like to recommend SOTA Beams for the swift delivery. Ordered on a Sunday and arrived on Monday.
    Have used the tape but unable to comment until the antenna has been exposed to the weather for a while.

  7. Liquid Electrical Tape

    Posted by Ken Chappell on 30th Jul 2013

    Whilst I can not write a full review on this product at this moment in time ( due to having only used the product once ) I can inform those that are concerned that this product is very, very good, and well worth the investment.

  8. Best Waterproofing

    Posted by Kev on 13th Jun 2013

    I am know on my 2nd can it is easier than tape you can get it into places that would be hard to get tape
    bought this of the net first time i used it, from N.A.
    cost a lot more with postage and the brush iside did not
    get all the wat to the bottom .this one from S.O.T.A. has a better length brush .

  9. Does what it says on the tin !

    Posted by Martin GW3XJQ on 29th Apr 2013

    Well this is the 2nd pot of liquid tape I have bought from Richard and it probably won't be the last. Enough said and after years of trying in vain to keep water out of coax cables using various tapes, including 3 M 88, Denso, self amalg etc. Follow the instructions and you will have a perfect water tight seal and I would never be without the pot in my toolkit.

  10. Easy To Use and Apply

    Posted by Mike on 21st Mar 2013

    I have used this before and found it to be perfect for my hobby of amateur radio. I enjoy building my own antennas and what is good is I can get the antenna in place and set the SWR and then seal up the components. Easy to use and apply. Works over amalgam tape for extra waterproofing.
