Wow, I had no idea that K3LR is not using Beverages! Don't verticals need
to also be away from towers to keep from having their pattern skewed?
I had a small lot at my P40A station and I used a K6SE Pennant. I liked
that it was ground independent. The Pennant was definitely better on RX than
my transmitting vertical however stations with Beverages heard much better.

Hello Lee;
Great to hear from you.
Yes - I have a pair of VE3DO loops - spaced 5/8 wave length - aimed at
Europe (also can be switched to 225). Then a single VE3DO loop for 135/315
degrees. It is all about more choices. I have a HI-Z 8 circle and a HI-Z 4
square - also spaced 500 feet apart - broadside on Europe.
There is a 5 element parasitic vertical Yagi for 160 that we use for TX and
RX - that has tremendous F/B (for 15 KHz of the band). This was published in
the Yagi chapter of the last three editions of the Low Band DXing book.
So 3 main sets of RX antennas. Any two of these RX antenna arrays can be fed
to the DX Engineering NCC-2 for antenna combining to develop incredible
directive patterns.
Beverages need to be away from towers and other antennas to work well. I
just cannot get them far enough away on this property to work - so they are
gone. The short vertical arrays work great. Twice we have worked over 100
countries in a weekend on 160 meters with this setup.
