[amsat-bb] suitable omni antenna for FM sats?

[Ron VE8RT]

Thanks John,

   that would be the easiest solution to start with.  VY0YL is s city
administrator, not someone with a technical background.  Maybe she
could get some help locally.  I have a Comet GP-6 dual band base
antenna still in its shipping tube, I haven't put it up yet so I
haven't tried it.  They advertise that it has 6.5 dDi gain on 2M and 9
dBi on 70 cm  I was going to match that up with a TM-V71A to see how
well that worked out.

   At this time, VY0YL has no antenna, or equipment.  As equipment that
won't do the job may be discouraging getting the first radio operating
the first time is important.
