200+ kilometers is not short range. Much farther than that and you get into beyond line of sight (BLOS or otherwise long range) systems which indeed use other freqs but they also involve sat relay systems or high power systems that bounce signal off of layers in the atmophere.

Short range applications will typically use an omni configuation in the UHF band with high output antennas so don't stand too close to UAV's that are operating for long periods if you want to have kids. 10 kilometers or less would be short range which several SUAS can safely handle.

But back on topic.

I have to agree with what has already been stated in the thread earlier. If the 2.4 issue was such an issue than it would reason that safety would be a major concern. How many 90 size helis are out there flying with 5+ foot rotors disks of death on 2.4? How many 33-40% airplanes that could go out of control and do major damage to property or maim/kill someone are on 2.4? Scale turbines flying 150+ MPH on 2.4?

To me it sounds like hog wash and not because there is not some new technology out there but rather if it was safety related and the AMA held onto this secret information I would have to question why I bother paying dues to yet another entity who would put corporate profits ahead of the well being and safety of the dues paying members.

Sounds more to me like the heads of state (Companies) are working with the AMA and waiting till their new product line is about ready to hit the shelves before making an annoucement that will be put under the guise of safety to push the new product. No different than when the glitch free 2.4 marketing blitz began other than this time with the secret meetings it would seem that the AMA is in line for some kickbacks.

Thats pretty much what my summary of this thread has come to.
