[amsat-bb] Antennas for AO-92 23cm

[Jim White]

Olde Antenna Lab makes a "wheel" style omni for this uplink.  I have one 
mounted and fed with 7/8" hardline but have not had a chance to wire in 
my 80W amp to give it a try.  I don't think Dave, W6OAL, has put it on 
his web site yet so you will have to give him a phone call.
