What if I just use the sloper type where there end feed at the top of a
Tower at 130 foot then the ends are open.
Tower Rohn 25g will be 120 130 foot high.
|\ feed point here do these type work well or not.
| \
| \
| \
| \
| \ open end here or
I can use the V type feed at ground level but that is lot of more work.
Which would work the best with low noise levels any ideas accepted.
I don't have the support to make the L s but do have a tower that I can
feed
I would love to L s in Four square but don't have supports for them as
of yet maybe at a later date.

Hi Kevin.
I have two types here - a K8UR style and an Inverted-L style - both
fed
with COMTEK boxes. The K8UR style array is 4 sloping dipoles with the
bottom ends tucked back to the supporting tower to cancel high angle
radiation. My K8UR is for 80M. My inverted-L array goes up 55 feet
and
then heads back to the support - that antenna is relatively new and for
160M. I've modeled these antennas extensively and no question - the
inverted-L approach is much better. You get a tighter pattern, a bit
more
gain and the effective ground radial area for the same results is way
less
for the inverted-L approach. The coherance for listening is also much
better for the "L"s but mostly I use Beverages for that... Were it
not
for some large trees that the K8UR array helps shoe horn in my 80M
antenna,
I'd redo it as an Inverted-L array.
I can give you more implementation details on either if
interested...
Tom, N5TW
