Re: [amsat-bb] Oscar-7 downlink antenna help

[Freeman Pascal <pascal@xxxxxxxxxx>]

My 10m receive antenna for AO-7 is a full-wave horizontal loop.  It  
has worked pretty well without a pre-amp, but I'm thinking of adding  
one up at the feed point for more gain.  This is a pretty small  
antenna to install.

I have also used both my Cushcraft R-7 vertical and G5RV with some  
success.  The G5RV has been modified with a SGC-237 auto antenna  
tuner placed at the beginning of the ladder line.  I tend to feed a  
bit of RF to it before the pass to allow the SGC-237 to optimize the  
match.
