[TowerTalk] Silver Epoxy for Antenna Work?

[Dan Levin]

In the past, I have used aluminum "welds" (actually brazes, using a propane
torch system) to attach capacity hat rods to aluminum tubing for my 40 meter
yagi.  The brazes are cracking, resulting in loose joints that arc.  I need
to come up with another plan.

One option is to use silver bearing epoxy to attach the rods to pieces of
aluminum angle, then use rivets to attach the angle to the elements.  This
epoxy is conductive, and appears to have been developed to allow repairs to
be made on PC boards.

Has anyone used silver bearing epoxy at RF before?  My concern is that
either the current carrying capacity isn't sufficient, or that it is lossy
at RF.

Thanks for any input in advance.  Comments of the form "why don't you use
attachment method X" are welcome, but I really need an answer to the
question "will silver epoxy work?"
