Since you're starting from scratch, and since you apparently want to do this
right the first time, what about doing a complete ground system like we read in
the Polyphaser papers (and elsewhere, including ARRL articles) in which you
surround the entire house with copper, with grounds rods at the corners and
interspersed between? And how about using copper strap (lower inductance)
rather than cable? Just a thought. Sure is nice to do this before the
landscaping and concrete go in.

Subject: SPG or whatever it is called now, to coax entrance ground question
I'm getting ready to connect to the SPG located at the power entrance of my
new house I'm building on my existing property. At this location I have the
electric, cable, and phone. I tried to locate this at the same side of my
house where my antennas are but the power company said no, it will go where
they decide it will go. It has been decided by them to be located about 60
feet from where my antenna entrance will be. Now as this is what it is, I
have a few questions.
I plan on digging a 2 foot deep trench, and burying a piece of 4 gauge
solid copper between the two. I'm going to make long flowing bends as it has
to run around the front of my house's front porch, around a corner then
another 20 feet to where my coax entrance will be.
How far or close to the house should I place it?
At the coax entrance I'm going to place two weatherproof boxes with the
Polyphasers in them from the two towers. How far away or close to(or on the
house?) should I place these boxes?
> From this point I will also tie into the two towers with a couple of more
runs of the 4 gauge copper. One will be about 32 feet the other 75 feet.
Any and all advice, or suggestions please as I plan on digging tomorrow
morning.
