It's an excellent compromise frequency as a lot of antennas cut for the FM part
of the band do really poorly down at the low end. Interestingly, that WB2MIC 2M
Cushcraft yagi the CVARC Club now has is one of the few high gain antennas that
work fairly well over the entire 2M band- Dave Olean, K1WHS, and I believe W1JR
before him, had a hand in designing that antenna while at Cushcraft. Dave said
it was a real challenge to get both wide band performance and retain decent
gain and pattern, If and when your club gets Dale, AF1T, to come up and give
his antenna talk that would be an excellent time to talk about the challenge of
making a wide bandwidth antenna.

Chip,
I picked 144.9 as a compromise between those with antennas cut for 144 - 145
(most weak
signal antennas) and those cut for 145 - 147 (most verticals for FM). ARRL band
plan says that
is a valid spot for weak signal.
If I used 144.2, I think it would create issues for many people with J-poles
or similar verticals,
and the real target for this net is those guys, not the people with serious
horizontal beams. Though
I hope we'll get some of those (like you)!

If "60 Minutes" isn't delayed by football I'll try to remember to
get on. My 2M antennas are cut for 144.2 and I don't
know how well they will work at close to 145, but I believe
SWR shouldn't be too bad. Worth a try however.
