| Fading is where the direct signal from the transmitter is cancelled by a reflected signal (180 degrees out of phase).
This is quite common with microwave systems because of the short wavelength. The good news is that path diversity can completely overcome it.
Path diversity means that the same signal from the transmitter is received of two different paths simultaniously. Seperating the receiver by more than 1/2 wavelength (62mm) solves the fading problem since if a local reflection cancels the direct path, the second path, by physics, cannot be cancelled.

| How common is it that the signal isn't picked up

We record 100s of fades per flight in the 'larger stuff' on any single antenna, but have yet to record even 1 lost frame as a result of fading on both antennas.

| Real world testing as described here by myself and a number of others would indicate that the AR6100 and it's predecessor will work in a larger heli/plane

You are loosing frames, but you just don't realise it. In foamies, where local reflections are minimal, the performance is great, but in the 'larger stuff' anything less than perfect, to me, is unacceptable.
The benefit of our wideband system to me has always been to provide a perfect digital link to the heli. That's the connected feeling you experience with this system.

Whats to say about the 7000. Fantastic receiver that works in anything. I recently sold all of my 72mhz gear.
