[amsat-bb] New M2 LEO Antenna System

Sure simple antennas work. DL7VTX just finished a vacation where he made
many QSOs from PJ7, J7, PJ6, and FS on SO-50 with a TH-D7 and a 5/8 wave
telescoping 2m whip. Let's keep in mind he was operating from islands,
likely in spots where he had an excellent view of the horizon over the
ocean and with virtually no RF noise. In other areas, a whip is not going
to work as well.

You are right that a whip should work pretty well on Fox-1A, 1C, EO-80,

But it depends what you are doing. Are you attempting to stretch the
footprint to work sub-1 degree passes of AO-7 or FO-29 into Europe or South
America? Are you trying to collect telemetry or command a satellite from
AOS to LOS? If so, you probably want something like this new M2 offering.

You contributed to this thread because you wanted to make sure that people
don't think you need a $500 antenna system to work LEOs - and that is true,
but on the same token, a $15 tape measure antenna will produce
disappointing results in most cases if someone is trying to make QSOs on
