YES on all!

Before heading to the big box stores for the big box whose photo I 
posted (where I got blank stares and no stock), I got prices on the 
internet. Also got a blank stare from the "nose in the air" contractor 
vendor who looked down on me because I wasn't a contractor. Good news is 
that a really good (but smaller) electrical supply store in town didn't 
give me a blank stare, treated me well, had three of them in stock, knew 
exactly what I wanted and where they were. Maybe 10% more than buying 
online, and I WANT to support GOOD local businesses like theirs. I was 
happy to carry it out of the store.

I have very limited experience in electrical construction, but enough to 
know to pay attention to exactly the issues Larry has pointed out. My 
cables enter from the bottom, the cable clamps, combined with wrapping 
the coax with enough tape to fill the opening with the clamps tightened, 
prevent both moisture and insects, the cable paths are very smooth, 
straight into the shack. Arrestors are mounted on Al backplate, which is 
bonded to the half-perimeter, multi-rod, ground system immediately 
adjacent.

BTW -- in my photo, the smaller box to the right of the old panel 
carries control lines for two rotators and a SteppIR, all on barrier 
strips.

I remember looking at KF7P's panels; mine have several advantages, 
including a layout that allowed more arrestors. This was 6-8 years ago; 
don't know what he's doing now.
