Re: uplink antenna for FM sats



John,
Good on the horizon, a disaster overhead. Any pass over 20 degrees or so you
will loose any gain advantage that antenna has at the horizon.  I run 50 W
into a 5/8 wave and above 20 degrees I get a stronger return signal from
FO-29 on a 1/2 wave QFH antenna pointed straight up.
