No. However, I think I talked to one of these guys a few months ago at Buttonwillow.

I will admit I was skeptical (still am) when I first read about this (a claim of 390K simultaneous users does not help!) but they at least comment on a "spherical" antenna pattern. For those of you that do not know, the 2 rx/antennas of the Horizon Spekrtum radio attempt to create a spherical reception pattern around the plane.

If these guys have figured out how to do that (spherical reception pattern) with what looks like a monopole antenna over a PC board, well they are really onto something bigger than RC radios I tell you!!

The basic radio they are using is similar to what Bob and I used, but we had to use 4 in the plane (all physically separated ) and 2 in the transmitter.

The reason for the physical separation of 4 radios is that the other problem we have with jets is massive amounts of metal objects in the plane, so even a spherical pattern antenna behind a big slug of metal shielding (big at 2.4 Ghz is anything bigger than a couple of inches, BTW) is still going to have "challenges".

I wish them luck.

The proof is in the pudding, they should just drag these out to events and fly them, they must have a bunch by now if they are shipping in a few weeks.
