Dear Friends,

Just a few comments on omni's.

The key to working the LEOs is really just a decent mast mounted
preamp. A Yagi is nice but I have worked 49 states and around 40
countries using just omni antennas on the LEOs. It really isn't that
hard, you just have to be able to HEAR the satellite and that means
a mast mounted preamp. I have worked AO-51 even on Field Day with just
an EZ Lindenblad on 2m and parasitic Lindenblad on 70cm.

The coax is not that important as long as you get at least 5 watts or
so at the antenna for the uplink. On AO-51, of course, the more power
the better because of the QRM but the satellite would be full quieting
at 5 watts into an omni.
