[Elecraft] Grounding negative side of power supply?

[Tom W8JI]

<<<I have a 120-foot run of 1-5/8 inch LDF7-50A Heliax that 
is grounded
at the base of the tower and at the cable entrance to the 
shack.  The
cable entrance is a 12x 16 inch aluminum plate that has 26 
coaxial
feed thru connectors (I have over 17 antennas).  The mains
(electrical meter box) is grounded on the other side of the 
house so
to bond them would take 50+28+50= 128 feet of ground wire. 
That
might be effective if It was #6 or larger.  I got better 
places to spend money.>>>

I disagree only on this one point Ed. The entrance ground 
must be bonded to the mains ground. Not doing so sets us up 
for very big problems.

As a matter of fact the better we ground our entrance panels 
and our antennas, the more we set ourselves up for problems 
from hits on the power line or power line faults.

My ground bonding connection runs directly under the house 
with wide flashing to my mains ground. I also have a halo 
ground surrounding the house that bonds my TV tower and 
everything else entering the house to my mains ground and 
entrance ground.
