Anyone looking at alternatives for an antenna for your APRS rig, take a look at these bent-whip, used Loran antennas: Comant CI-122SP.
I just bought one for $9.95 on eBay. They are apparently removed Loran antennas and there should be plenty of them around now. The nice thing is that they exactly match the two Comant CI-122's that I have for COM1 and 2 now. As near as I can tell, they are basically a CI-122 shortened to 20" for Loran. Obviously Loran, being in the 100 kHz range, is using some other multiple of wavelength other than 1/4 wave. So near as I can tell, 20" would be about a perfect 1/4-wave for 144.390 MHz; and they have a BNC connector, what's not to like?
I spoke to my avionics shop here on the field and they know of no reason why these shouldn't work. If anyone does, please speak up!
