Hiya...

Been a while since I posted here. *For the sake of noise suppression as
affective lightning protection is almost hopeless without gas tubes,
what would be the minimum gauge wire that you could use for a ground
from the radio to a ground spike and from a matching transformer to a
ground spike ??? *Yes, I know there is loads of info on the net, but I
would like some active opinions as some recent discussions I have had on
this has been conflicting.

Also... I've gotten conflicting opinions on this one too. *If you have a
long wire or beverage set up on a matching transformer like the ICE 180,
there is a ground receptacle on the matching transformer. *Would you:

A. *Use a separate ground wire from the matching transformer to the
ground spike and another separate ground wire from the receiver to the
ground spike ???

or

B. *Use one single ground wire from the receiver's ground port going up
to the matching transformer and then to the ground spike ???

I know this stuff is antenna-101, but I'm interested to see what the
opinions here are

Thanx in advance !!!

Try both ways. *I have my MLB grounded to the support mast via the outer
conductor of the RG58, about a foot from the near end of the random wire.
The mast itself is grounded.

If your balun and coax is up in the air, you don't have an effective RF
ground to prevent common mode noise on the coax shield. That's why the
balun needs to be close to the ground so you can use a short ground wire
between the coax shield and the ground rod. This is how you achieve an
effective RF ground on the coax shield. It also provides a vertical
section of the antenna coming down from the horizontal wire. This is
required for a true inverted-L antenna. The vertical section (wire)
sometimes picks up a better signal than the horizontal wire of the antenna
so it's best to have both sections in use. Having the balun near the
ground allows for this configuration.

It would seem as if this is what I'm going to try. *If I keep the balun up
on the roof, the only thing I have up there that approximates a ground is
the chimney. *I'll move the f***ing balun down to the 6" brass ground spike
and connect it to the ground spike with a one foot #4 THHN copper cable.
Then I'll run the receiving wire like an inverted L. *Now, I'll have to run
about 90 feet of coax from the balun into the receiver.

I would imagine that the receiver itself will be grounded and will not need
its own separate ground connected so long as this antenna is plugged into
it, no ???

Next question. *The height of the house is 30 feet and the width is about
the same. *The inverted L receiving wire will be 30 feet up and 30 feet
across. *

- What type/gauge wire would be best ???
