Warren:
I'm sure others on the list will provide their suggestions for the
ground panel. Allow me to make additional suggestions for you to consider.
The contractor ought to be able to install your ground rods for you.
Believe me, it takes quite a bit of effort to pound in 8-foot long rods into
some soils (like here in the DC area.) He can also dig the trenches for
your ground conductors as well.
Also, ask (pay) him to open the conduit trench(es) between your shack
and the towers, install the conduit system (I'd recommend four-inch diameter
schedule 40 PVC minimum) and pull ropes and close the trench(es). Saves you
lots of back-breaking work.
Depending on timing of the house completion and tower erection, you
ought to consider getting him dig and pour the tower foundations, as long as
he's going to have a concrete truck on your property. You might have to get
the tower permit (if any is required) earlier than you had anticipated, but
it will probably be cheaper than having someone come back later for a small
job of a few yards of concrete.
Finally, if you decide to use an enclosure of some sort for your
grounding panel, take a look at Hoffman enclosures
http://www.hoffmanonline.com/Product_Info/index.html . I have one of their
boxes at the base of my tower. It encloses the Polyphaser surge protectors
for the antenna coaxes, plus the antenna switch. I have a second box on the
wall outside my shack. That one contains my SPG panel, ground bushings for
the outer coax shields and a #2 connection to a final ground rod a foot away
from the shack wall.
