I'm getting set up to capture telemetry from the sats. I have the Funcube Dongle and FIAB on a Raspberry Pi.
What antenna is suggested?

Bob,
When my K3RLD-RPi station was active, I was averaging about 70 frames a day between 4 satellites (AO's 85, 91, 92, and 95). The antenna was a 3/4 length (~60 inches, if I remember correction) vertical with 4 horizontal radials of the same length. This was mounted in my attic with about 6 feet of feedline (RG-8X) to the FCDPP.
Not suggesting it, just giving you a data point.

Interested in what software your going to use for telemetry decoding.

Thanks Roy.
Stephen, the FIAB SD image includes FoxTelem and starts it automagically upon boot.

It depends on your goals.
If you want the absolute maximum telemetry, then you want a regular beam and rotator, same as you would use for QSOs. I have that for normal SatCom and some coax switches/relays to switch it from my radio to my FunCube Dongle/FoxTelem.
Normally, I use homemade Lindenblads for my FoxTelem telemetry and also the same set with a splitter for my SatNogs station. The most recent AMSAT Journal had two designed for 3D printed 70cm Lindenblads, although the ones I am currently using are AA2TX's (search for AA2TX Lindenblad--there are two different articles/designs, one for each band).
I have also mentioned in the past that I have had surprisingly good luck with an Arrow Antennas dual-band J-pole. It is not going to pull in as much as a beam and has a few null spots (like right off the end), but it is inexpensive, dual-band, no building required.
