[amsat-bb] Re: AO-7 Antenna Polarization

[Glen Zook]

During the first year, or so, with AO-7, I used horizontal polarization with the 2-meter and 70-cm antennas elevated about 30-degrees.  The 10-meter antenna was a 2-element yagi horizontally mounted.  Only the azimuth was varied.  Later I added an az-el rotor for the 2-meter and 70-cm antennas.  However, the 30-degree elevation worked very well.

hello Ed...I have found that with AO-7 over the years...it depends... of what I am not sure..be it satellite orientation, local issues, or simply "propagation gods". There are times when switching between L & R on either up or down link will improve reception. My current installation is currently not wired for switching and defaults to RHCP for up and down. I do not appear to have any issues with AO-7, I do plan to connect up the switching simply because, it's there.

Can someone tell me what type and polarization the antennas are that are 
currently in use on the AO-7 satellite? 
I've done many searches and cannot find this information anywhere I have 
looked.
