Interesting, Zack.

I would ask them about transmitting through the one with the preamp built in. Can you do it? (i.e., is it RF-sensed/switched)

Or does the preamp make it a "receive only" antenna, with the accidental transmission through it smoking the device :) It's bound to happen on a dual band radio...

(I think you'd be better off building a pair of AA2TX style Lindenblads...)
