Zyfer (formerly Odetics) use the VIC-100 antenna. Has about 30dB gain, 3 pole filter and works well in noisy environments.
Using 4 of them right now, inside my office - single storey extension - flat concrete roof, with them all next to each other strapped to the inside wall approx 6 inches from ceiling (no external access just yet!). Tracking several satellites on each on the two CommSyncs I'm testing.

I bought mine on eBay, new in original packaging for $50, a short while later someone sold a bunch of them (these may not have been new) for $15 to $20 a piece. Anyone has compared them in actual operation or performance?

In short, you have one of the best timing antennas out there.
