I'm controlling my 8x2 Antenna Genius from the per-band switched 12V 
outputs of two 5B4AGN bandpass filter band decoders. The 5B4AGN unit is 
driven from the K3 ACC output. The Antenna Genius is pretty flexible in 
how it can be controlled. There are dip switches that select the control 
logic. The manual is online, but when I was installing my Antenna Genius 
a year or two ago, the 8x2 was a brand new product and the manual wasn't 
as complete as it should have been, so I had to get pin-outs of the DB 
connector from Ranko via email.

The Antenna Genius 8x2 has EXCELLENT RF performance, with greater than 
100 dB isolation between outputs for any combination of selected outputs 
on all bands, and very low SWR. My measurements were done with a 50 Ohm 
VNA and all unused outputs unterminated, which is worst case.
