There are over a million frequency combinations that out equipment can lock onto. Not exactly a small spectrum. I would love to know where you are getting your information. To interfere with our systems at all a signal has to have the same frequency, encoding and power level! That just really dosent happen in the real world. The bodas do have to be horizontal for full range.
Have you looked at the frequency range allocated to 2.4gHz band that we utilize?
There are not "over a million frequency combinations", rather there is a rather narrow narrow BAND of frequencies from 24.05mhz through 24.6mhz.
The receivers can lock onto thin subdivisions within that range giving us hundreds ( not millions ) of "slots" within that band.
But any wide band transmission can swamp the entire range.
In the vicinity of towers, etc... that is exactly what happens, and in spite of your 2.4gHz FHSS radio, you have problems.

Then again I have 15 years in RF experience and currently work at a company called Randtron Antenna Systems. I suggest you look it up.
Thanks I did.... and experienced it directly too.
"2.4GHz radio systems are rapidly replacing the older narrow-band systems that we've been using for many decades.
The advantages of 2.4GHz are manifold and include elimination of the "shootdown" problem and (
in theory) a reduction in interference.
However, the 2.4GHz band
is often filled with the transmissions of many different devices, all competing for valuable space and each trying to make its own signal heard above the noise.
In most cases, good 2.4GHz RC equipment can cope with the signals created by cordless phones, microwave ovens, WiFi, bluetooth and even video transmitters but,
at some locations there are occasions when the amount of noise is simply too much for any RC system to cope. That's why a self-contained portable spectrum analyzer (SA) is such a useful part of any club or modeler's field equipment.
With such a unit, you can keep an eagle-eye on the noise levels at places where you fly and even log that data over an extended period.
If a model on 2.4GHz crashes or experiences lockouts, you can quickly check to see if there was any interfering signal present at the time. At last it becomes possible to determine the real cause of those unexplained crashes. "
