The AR8000 has a main receiver with one aerial and the AR9000 has a main receiver with only one aerial. Is there any significant difference in the quality of perceived signal. If no then why have two on the AR9000 and if yes then presumably the AR9000 is significantly better. I am have trouble understanding the logic used in the variants since it is impressed upon us as the buying public that there is signal diversity; if so then surely the AR8000 is a poorer brother to the AR9000 (or any type using a twin aerial arrangement on the main receiver.
I can't say if the AR9000 is better than the AR8000 due to the number of aerials, but I can say the AR8000 has OUTSTANDING reception.
I walk range test all my new radio components to determine the actual full range.. and the AR8000 is one of the best I have tested..
In fact.. this RX when bound to a JR 11X IS the best i have tested..
Each aerial definately contributes to the overall signal as I shield them all then expose one at a time to test them..
Any single one aerial alone gives great range on the AR8000 and all three combined works even better..
Here is a vid of it with the JR11X (I trust it on my Favourtie 450 Heli)
