[TowerTalk] #2 solid or stranded for tower leg grounds (Oops!)

[wa5zup]

Thanks Roger
I will check local electrical supply houses.  I live in small town USA.  I
have to get stuff from Albuquerque most of the time at work.  I buy from
Graybar in Albuquerque most of the time, using the work account there.  I
just ordered the rest of the #2 solid wire I needed from them, no one here
had it, except for jacketed #2 stranded.  I will see what part of an arm and
a leg they want for those.  Anything not made of copper, now days, is much
more reasonable at least.

It'd probably help if I'd include the link

Watch out for line wrap.

The TA-800 could easily be opened up from 5/8" to 3/4"
