Low Altitude Blackout?

Recommended Posts

I went out for an FPV flight today for the first time in 5 months with the same equip I have used before: A Range Video 500 mw tx/rx setup with a 14 DBI patch ant. Like before, I had my wife point the ant. at the plane but, unlike before, I started getting complete blackouts as soon as I came down to lower alt., under 100 feet or so. High altitude was no problem not even any interference at all. I trashed the plane as a result . . . :angry:

Any clues as to why it would be doing this when back in December it worked without a glitch? :(

the blackouts came in pulses ?

or compleetly off from one sec with no warning ?

I think it is simply since your antenna is not circular polarized

and the plane is not

and unlucky height from ground = reflections

give you multipath fading

Thanks. Yes, it came all of a sudden with no warning and lasted until the plane crashed. I checked the connections and everything seemed okay. I will try going with a whip antennae instead of the patch and see if that helps.
