[TowerTalk] Force 12 antenna part

[john at kk9a.com]

Stainless steel and aluminum are pretty far apart on the galvanic table.
In a corrosive environment the bolt would be difficult to take apart no
matter what precautions were taken. With a little craftsmanship you should
be able to find something at McMaster-Carr that you can use to make
replacements out of.

If you're rebuilding linear loaded elements I would consider changing the
loading wires to coils.

###  I have seen the same identical  6  x sided aluminum stand offs , 
with  1/4-20 threads in both ends..at local big box stores.   The F12
version..on SOME of his versions,
also had a aluminum piece welded to the outboard end.    Some mode;s did
not have the welded end..and just had a hole in the side for the alumo
weld wire to slide into.
