Re: TS-711 and TS-811 control and QFH antenna ?



>From what I've observed TXa (.150) is LHCP, TXb (.300) is RHCP.

Polarity doesn't change based on what hemispere you are in, only the pattern of the UHF antennas, which favors the Northern Hemisphere by about 10 dB. Also, the L/S antenna is on the -Z side, which also favors the northern hemisphere, and is linearly polarized.

Most of this and much more is covered in the revised Echo book by Gould Smith WA4SXM, and is available from the AMSAT store at http://www.amsat-na.com/item.php?id=100047 . Every user should have one!
