Thanks for the rover ant suggestion. I may give it a try.
As for John's 10 el 2M ant, I've used one on 432. As you say the max
gain is at 45 deg off of center. I did some testing with a local and he
reported it 2M ant was about an S unit and a half down from my 8el 432
Quagi. Over a longer path (100+ miles) the quagi was definitely better
but not 1.5 S units.
