[Boatanchors] Antenna Sealing, thanks all. Another question. . ."Liquid Tape"

Fri Mar 11 06:07:56 EST 2016

West Marine sells "Rescue Tape, a self bonding silicon based product"
I've used this tape on extension cord plugs for Xmas lights and repairing line cords, but have not tried it on coax connectors.
I do not know the UV properties.

Another question. . ."Liquid Tape" 
Years ago, a friend who worked for MaBell as a cable spliced turned me on to a very good system using Scotch 333 electric tape and a brushable liquid called Scotchkote. Very nasty stuff to get off of clothing or skin.

First a layer of 333 followed by a covering of Scotchkote. Let it dry and then repeat the process. It makes a waterproof seal that can be removed with a sharp blade if needed.

Works great in buried cables.

The results have been great.  Acetone is the solvent.

        thanks all. Another question. . ."Liquid Tape"

First I want to thank those who took the time to answer my "Antenna

Sealing" questions concerning sealing "joints" on a Tram 1481 3 section

2M/440 antenna.  It seems that at least SOME RTV products are to be

avoided.  Now I have another question.

After thinking about it, I thought of something I saw at Harbor 'Fright'

quite some time ago.  That is, Liquid Tape.

It seems that IF I first used good quality black electrical tape, then

sealed it with one of the following products I would end up with a GOOD

seal that could be removed by slitting through both the liquid and

plastic tape with a knife then peeling it off.  NOT sure how easily

liquid tape applied directly to the joint without regular tape under it

could be removed.

It might seem like I'm going to extremes here, but like I said in the

first email, once I put it up, I want to leave it up.  At 72 it's

getting a little bit harder to easily work with antennas 'solo'.

Here are a couple different products that might be suitable, one from

Harbor 'Fright', the others from Amazon. . .  I have an HF store in

town, but if one of the Amazon products are doable I might go that

route, though I'd have to wait till next week to order it.

http://www.amazon.com/s/ref=sr_1_5_hso_sc_smartcategory_1?rh=n%3A256161011%2Ck%3Aliquid+tape&keywords=liquid+tape&ie=UTF8&qid=1457634227&sr=8-5-acs

As a side note, I thought I might get a can of the Liquid Tape "Spray"

and spray the bottom of the bottom mast section where it will be buried

in the ground about a foot.  Hopefully that would prevent the buried

part from "rotting" (rusting etc).
