I saw your recent video with the helical antenna and the cloverleaf together.
Now I thought; if you put three helical to the horizont and fly from the beginning e.g. to the south, if from the north you get a signal from e.g. a surveilance cam or another fpv which is a very low signal. Once you will be far away to the south your diversity could switch upon a time to this other signal when it becomes better than your plane's. This could lead in a "hijacked" signal and you will loose your plane.
What about a button like auto/manual1/manual2/manual/3... where you can toggle through the input channels, just in case to force the right signal??

Hi...
I don't pretend to speak for Bruce... this is just my understanding -
I think Bruce is considering using 3 helical receiver antennas + their 3 associated
video and
audio receivers to cover a 180 degree arc for long range reception
within that arc; plus the CP skewed co-plainer antenna for close-in work (eg. take off & landing) that will cover 360 degrees.
Additionally the video Tx and all of the Rx's are on 5.8Ghz... not much happening in that associated bandwidth really and especially where you would be flying your model.
IMHO if you are going to fly long range (and by that I mean the model is far enough away that you can't
see it's attitude) ReturnToHome (A.K.A ReturnToLaunch) are pretty much mandatory requirements. There are also the Fail-safes built into the better RC controllers (eg. FrSky) to help. If on the off chance you do encounter some interference in your received AV signal (the facility providing your FPV view-point) regardless of it's origin then a simple switch on your RC will bring your model back to you and at some point
on it's way back you will probably have your FPV signal available again.
Anybody else see it differently?
