Thanks everyone

The shack will be run off of solar power only and 95% of everything it it
will be 12 volt. It will have a 1200 watt inverter to run different AC items
as needed ( a soldering iron comes to mind)

I plan on grounding the sheild (for lack of a better term) of the shack, to
my lightning /RF grounding system. There is no way that I would not ground
the hell out of something like this.

I use LMR 600 and 400 for the coax runs.

The sheilding does not need to be perfect, just good.

thanks again..
