of the dipole antenna wire and run back with it toward the houes? This is
basically to keep a big loop from hanging down and also keeping the wife
happy since it would look much cleaner. I didn't know if this would have a
large impact on operation or not.

Hi Doug,

I'm Running the Windom ( OFCD) it identical to what your saying. but
you'll find that the coax needs to come off the antenna in pretty much a
90 degree angle. ohterwise you will end up with lots of fedline
radiation which will cause problems in the shack.

Can you give me an indication about how long a lead I need before
running the coax back toward the house and into the radio? I'm going
to run the coax up the house and out to the feedpoint.

90 degrees under the antenna, not perpendicular at it's elevation. Get as
far away as possible, burying the feedline so your earlier dilemma will not
be worsened ;-)

I know my wife just _loves_ seeing that feedline "drop out of the sky" in
the middle of the lawn. But that's the way the antenna is designed. Suggest
you try that, determine it's efficiency by whatever means you can, then try
running it straight over to the house. I think we all agree it will lose
some output power back onto the feedline, but you could handle the safety
issue there, or try, with some RadioWorks line isolator products.

Hi again Doug,

Was out of town so did not get your question for a few days.

You should run it away from the antenna at 90 degrees for about 1/4 wave
if possible. on 80M that would be about 66 ft. but as far as you can
in any event. some claim choke balun at 22' down the feedline works
well Mine is about 30' then a choke balun then about 75' to the shack
and it seem to work for me.

I do have 1 other option. I have some 50' trees that would stretch about
130' apart. The issue is they are about 200' from the shack. Can I run that
much coax?
