ao-7 antennas for portable use
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
Hi Norm,
You asked about ...
Pictures of antenna arrays would be greatly appreciated
Bill, OM3BD posted photos about their AO-7 setup when he and Wyatt, AC0RA set the new distance record on that satellite. Here is the link to Bill's web page: http://www.qsl.net/nz5n/AO7record.htm

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!
