Re: [amsat-bb] Fox Telemetry antenna?
I've been using a 3/4 wavelength ground plane (vertical with 4 equal length radials) in my attic for the last couple of years, and have usually been in the top 60 on the leaderboard for the fox satellites. Lately I've been having FoxTelem stability issues, though (pretty regularly getting a usb access error).

I'm set up with 2M, 70cm, and 23cm CP antennas on a G5500 rotator but I understand I can also use a fixed antenna such as a Lindenblad or quadrifilar. Suggestions?
I have two systems, one with a Lindenblad (AA2TX design, homemade) and the other with a dual-band J-pole. Both work pretty well, but not as well as a beam on a rotator.

I don't want to wear out my G5500 so I'm looking for the best alternative antenna(s) to collect telemetry data.
How about a dual-band Arrow antenna pointed straight up? Surely that's better than the J-pole but not as good as the CP Lindenblad.

Sounds like we need an electrically-steerable phased array for 2 meters. :-)
At 70cm, it might be practical.
