I have a set of L-tronics 10129 fore/aft antenna mounts, but unfortunately they don't have the actual antenna whip itself. I've not had any luck finding compatible antennas for them. Anyone know a source for them?

According to the manual, the antenna length is 22". Ideal spacing is 20"; useful spacing is 12"-26".
