[TowerTalk] Balun filler

[Sam Effinger]

Question:  I am going to build a 1:1 balun and want to put in in a PVC pipe..the question is what can I fill the pipe with....I am thinking about filling the pvc pipe with that expandable foam that is used to fill cracks around doors etc.


Is that stuff corrosive ...any heat concerns ??

I know some folks use it in the end of elements to seal the end and hold the rope in place..but will it work for the seal in a balun ???

Glen K6NA makes the best baluns and uses epoxy ( he isn't making any at this time )...I don't want to buy all the epoxy as I only want to make a couple..

any ideas ??


Thanks for any help...

Life is good....
