In Aruba, I had a K6SE(sk)pennant 6' from my TX vertical and I found it to
be a useful antenna. It is a good 160m RX antenna. I had played with a
K9AY loop however went with the pennant because it was not ground
dependant. The K9AY loop does have the direction switching advantage.
Unfortunately with a small lot and a lot of local noise, there is only so
much you can do.

Array?

I'm in need of a decent 160 receive antenna that can fit in my 144 ft
(N-S) x 44 ft (E-W) noisy urban lot. I'm surrounded by (old) power lines
and near a high power AMer (WFED, formerly WTOP) at 1500 kHz. The 160 and
80m inverted L's and 40m half-square run N-S from the back of the lot to
the front.
I've played with EWE's and Pennants, both of which are rather mediocre.
Generally speaking, the Inv-L's have been better, albeit noisier, receive
antennas.
I've looked at K9AYs and now the KB7GF array, which seem to be quite
similar. I'd like to think I can fit either in my backyard, but if I do,
they will be very close to the TX antennas... *maybe* 20 feet from the
verticals, and certainly underneath all the wires. Is one substantially
better than the other?
A major criteria is that the horizontal sections (wires) have to be 10
feet above the ground... I don't want to behead anyone walking in the
backyard!
Is this all a pipe dream?
Sagely advice is appreciated.
