[amsat-bb] Re: Mode A antennas?

[w7lrd@comcast.net]

Hello John 

This may not apply to you but I'm sure some others will benefit  I have a 4 element cubical quad at about 50 feet.  It is tuned for about 28.3Mhz.  Now at 29.5Mhz the reflector is acting like a director and it actually "hears" better off the back than the front.  I noticed this back in the old RS satellite days.  The 10M downlink on AO-7 is to say the least, lousy, usually good for CW most of the time.  The AO-7 log says it all.

What is the minimal antenna you can use on 10m to hear the AO7 downlink in Mode A?  I have a homebrew G5RV type antenna up and can't hear AO7 on it at all.  What kind of antennas are others using on 10m for mode A?
