Blair, depends on what you'd like to do with it. A horizontal 160 ant that low
will warm the clouds with its very high radiation angle. Any component you can
get vertical will probably be a huge benefit if you want good success across
the pond. If local short range is your goal might not make all that much
difference.

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
horizontal.
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.
73,
Blair NP2F
