Dave's system will work, except that harmonic radar bounces off of wire
fences, cars, etc.  I know, we have 3 harmonic systems.  It also simply
give a ping, does not I.D. the owner of the hive.  If more than one
beekeeper uses harmonics, it gets tricky trying to determine who's who.

We have an active RFID that transits over a 100 yards,and one of our
associates has a small tag that is cheap and readable from a plane.  Its a
bit early for mass production and sales, but its coming.  First step, I.D.
the equipment.  Second step, provide location and I.D. at a distance.
