I forgot to make it clear that you should feed the antenna at the bottom, as
a sort of modified Inverted L.  I would not recommend feeding it as a
dipole.  When you feed it at the bottom you will need to add some ground
radials. Length is not critical.  More is better when considering radials.
Start with whatever you can lay out (try for at least 10 to 20) and then add
more as time goes on.

Hello towertalk group,

I'm getting set to put up a wire dipole for 160 meters.  I'm considering 2
options, and I wanted to hear which one you guys think might be better.  The
feed point will be about 38 feet up on the side of a tower near the house.
>From there, I have just enough room to stretch out a full quarter wave to
the back edge of my property, where I can get about 25 - 30 feet of height
in a tree at the other end.  So this leg of the dipole will be pretty much

For the other leg, I don't have that much room.  I will need to put in a
loading coil.  I have about 60 feet to a tree in the front yard, where I can
get about 25 feet of height.  This is what I was planning, but I also
thought about bringing that leg straight down from the feed point.  In that
case, the antenna would have one full-length horizontal leg and one short
(about 30 foot) vertical leg with a loading coil.
Do you think anything would be gained by having part of the antenna
vertical?  Would I get some lower-angle radiation if I did it that way?  Or
would it work better more or less horizontal?

Thanks in advance for any input.
