Where he lives a common mode antenna is most likely the
worst choice for an antenna anyway.

What antenna would you recommend ??? Besides dead poultry.

People that meet RHF have a tendency to slap him over the head
with a dead chicken in case you were wondering where that came
from.

Anything not a common mode antenna such as a random/long wire.

Make a dipole or a loop antenna. Those antennas don't need a
ground to operate.

I already have a di-pole. *A 102' G5RV on my roof. *I'm building
a second antenna because my current 150' long wire has fallen
apart on the roof after being up there for three years. *I have
an ICE-180 balun that I can take off of that mess, so I figured
I'd use that in the construction of something that can make use
of it, like an inverted L. *So far I just spent money on a new
6' ground rod and a 20 buck spool of antenna wire. *Under 50
bucks total. *Why the hell wont I get an effective ground here
with a six foot ground rod ??? *I always thought the ground here
in this area had great conductivity. *That is why there are so
many MW transmitters here.

You should get a good ground with a 6 foot rod. I was commenting
on the retard from the San Francisco area spouting advise about
the rod for different soil conditions than what you have. Chances
are for you the water table is about 2 or 3 feet below ground.
Chances are you have 4 to 6 inches of top soil then several feet
of clay.

You were complaining about area noise before this and a common
mode antenna would be the worst way to go if you are surrounded
by neighbors with noise makers.

BTW... My G5RV works very well from 5 megahertz to 10 megahertz.
*Is isn't so good below of above that. *My 150' long wire was
great for anything above 10 megahertz. *Unbelievably, it was
also very good for 3 megahertz to 4 megahertz. *I have no idea
why. *The way I had that one grounded was, I'm sure, a poor way
to do it. *I have a 12 gauge wire going from the radio, up on
the roof to the ICE-180 balun's ground, and then back down the
house to a ground rod in the earth. *The current ground rod is
only 3' long iron bar. Don't ask me how, but it worked.

Any time you have a wire in the air of an electrically
significant length then you do not have a ground wire. What you
have is a counter poise and its electrical length will sum with
the characteristics of the Random/Long-wire that is the other
part of the antenna. The length is the important consideration
not the diameter.

You have made the investment so go and install the inverted L.
Keep it as far from your house and the neighbors as you possibly
can. If you like the performance, and the coax is traveling
across the ground to get to your house, you can bury it in a
trench. You could protect the coax in the ground with PVC pipe or
buy the type of coax that is designed to be put in the ground.

There is no point in running another ground wire from your radio
to the antenna ground point. The coax shield is that connection.

You would want a separate ground for the antenna ground at the
ICE BALUN because the ground at the radio is from the mains and
is contaminated with electrical noise from other devices.

The ICE BALUN is really an UNUN in this case. Unbalanced antenna
to Unbalanced transmission line.


- For the inverted L, what tap on the the ICE-180 - should I use ???
300, 450, 600 or 800 - - Michael -

Michael,

As others have suggested try each Tap one-at-a-time to find out which
is best for you; your conditions; and your set-up.

Do this over several Days during different times of the Day.

Record your Observations and then Review your Notes to decide which
Tap gives you the Best Over-All Performance.

I don't that is necessary. What is important is note the differences on
a stable signal over several frequencies of interest for a tap. Time of
day is not important. Chances are one signal will suffice for finding
the best tap. Chance are in will be the lowest one anyway.
