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 !!!

First, the balun shouldn't be up in the air. It should be close
to the ground at the lower end of the vertical downlead wire of
the inverted-L antenna. Then you can use a short, less than
three feet, length of grounding wire from the balun to the rod.
The ground wire should be at least 10-gauge, preferably larger,
like 6 or 4-gauge. The coax should run on or in the ground to
the house and then to the radio. This will prevent it from
picking up noise on the coax shield, which can happen when the
coax is up in the air. It's not absolutely necessary to ground
the coax shield again near the radio if you follow the above
advice.

Thank you for all the replies. My evil plan is this. Since I
cant get the matching transformer away from the house, I will
secure it to the house's brick chimney. The chimney goes all the
way to the concrete foundation and should make an excellent
ground.


Please explain why you think a 'brick chimney' will make an
excellent ground.


How about, the best thing approximating ground that is available on
my roof ???


Get a dead chicken from the market, put it in a paper bag, stand up on
your roof swinging the dead chicken in the bag around in a circle above
your head and chant RHF, RHF over and over until your reception
improves.

If that does not work try shouting Billy boy while doing the same.
