There were a few of these fold up mag mount antennas on Ebay recently and they work great with a PRO-43 while mobile. So far I've only picked up a few pirates but they come in full quieting.

Brazilian's pirating US UHF satellites, listening from my driveway on a R/S PRO-43 scanner. Its fairly common to pick them up in the 260MHz range and they come in very well with this military mag mount satcom antenna.

I got two, the first was a buy it now for $175 and the other came from a private seller for $35. In the same week I also got a fold out portable satcom antenna that I should probably sell, gotta thin out the herd a little because I can't possibly play with them all.
