Also do a search for Polyphaser company. They have several publications on
grounding and such and contain a wealth of information. They also make
excellent quality suppression devices, etc.

Mark,

I put my tower about 250 feet from the house.  This means most of the
noise generated from the house is greatly reduced.  I have almost no
computer noise or TV receiver noise.

Getting the antennas away from the house helps a lot.  I have a 250 foot
hard-line run from the house to the tower.  I got this hard-line from the
local
cable company.  It was a scrap piece to them.  I buried it along with
rotor control cable, and a 22 wire control cable for miscellaneous
functions.
I relay switch all my antennas with a switch from the shack.  All this works
great.  I wish I had run 120v out to the tower for soldering out there.  I
used
a ditchwitch to bury the cable.
