Jim / Don, thanks you both for your input. Albeit brief, I now have food for
thought and some bedtime reading to do on Beverage antennas .

I don't completely agree with that. I have a pair of 2-wire Beverages
that are approximately one wavelength on 160M. I use them on the AM
broadcast band and find them quite effective as RX antennas. They are
not as directional on the low end of the band, but they still have SOME
directivity, and with the DX Eng preamp, they are quite sensitive.
After installing my new synth boards in the radio with the KBPF and
doing the mods, I tried listening down to 100 kHz. Around mid-day, I had
good copy of a CW beacon about 125 miles away. These antennas are too
short to be called Beverages at those low frequencies, but they do work
well as RX antennas.
