Norm,
I use an Elk log periodic for AO-7 and all my other satellite work. I am able to work passes to the predicted LOS time, subject to local surroundings. I was only able to work down to 4 or 5 degrees elevation with my Arrow dual-band Yagi, before I switched to the Elk. You can see this setup in action working satellites - including AO-7 mode B - in some of my videos at: http://youtube.com/va7ewk
For AO-7 in mode A, the Elk is my 2m antenna, and a Buddipole dipole on its tripod and telescoping mast is used for the 10m downlink. Since this requires more setup, and the 10m downlink is weaker than the 2m downlink, I don't work mode A very much.
73!

Hi all! Just wanted some comments as to what ops are using for AO-7 portable. More importantly, some info on how they perform near loss of signal. Pictures of antenna arrays would be greatly appreciated. Norm n3ykf _______________________________________________ Sent via AMSAT-BB@amsat.org javascript:;.
