The other weekend I flew out to 2.5Kms using the helical with solid video all the way and I flew a circuit of about 1Km radius around the ground-station with not a single drop-out.
That's using just the 5-turn helical and a SP through the diversity controller.
Rixx wrote:Bruce, how far are you from releasing circuit schematic of your controller? I'm trying to recreate dual diversity controller around arduino and 4066, but I cannot get nice picture out of that CMOS gate. I connect video output from RX straight through 4066 and decoupling 470uF capacitor to LCD. The picture is very dark, fuzzy and colors are messed up . It is definitely that 4066 stage, picture is perfect if I jumper the gate with wire or tweezers or screwdriver... I'm apparently missing something, impedance matching resistors or video buffer or something that you might have on the underside of your board that you do not show in youtube video .
Any advice highly appreciated.

Yeah... interesting how the SP worked so well out to 1Km for as much of the real estate as the controller saw fit to use it.

I don't get any loss of color and only a very, very slight loss of video bandwidth with the 4066 but it's very hard to notice any difference between the direct feed and a gated one.
Are you running your 4066 at 5V?
