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.
The AR9000 has 2 Receivers inside the main Receiver case, with 2 antennas. It also has one Satellite Receiver, with 2 antennas, and the ability to add one more Satellite Receiver, with 2 antennas.
If you attached a Flight Logger, to the Data Port on the AR9000, you can track how many times each antenna loses the signal.
