Dave et al,

A diversity RX antenna doesn't need to be complicated.  All you need is
something that is somewhat different than your TX antenna.  By "different" I
mean:

1. different polarization (e.g. a vertical if you're using a Yagi).
2. different takeoff angle (e.g. a low tribander you're using a high one)
3. different azimuth angle (e.g. a tribander pointed in a different
direction)

Your "Beverage" was probably acting like a low horizontally polarized
antenna with a high takeoff angle, so it filled several of the above
criteria.  If you do use another Yagi, take precautions to limit the RX ANT
input when transmitting.

73,  Bill
