[TowerTalk] Homebrewing Verticals

[Jim Rhodes]

The last time I did this I was walking though the sporting goods section 
and came accross the tubes that you put golf clubs in to organize your golf 
bag I guess. Anyway I used 2 layers, had to split 1 I think (it has been 10 
years or more) and they still seem to be holding up OK. Haven't checked the 
insulator for a few years. Seems like I alway have to replace the feedpoint 
SO239. YMMV
