I guess you could call it outrunning the camera.
Here's what was happening to my Voyager WVOS511 mounted on my 2013 Cedar Creek 36CKTS and my friend Ike's Furrion on his 2015 Cedar Creek 36CKTS with camera antenna at rear of 5er.
The screen would lock up or show no signal. I called RV Cams and ordered an 8' extension antenna. Reception got a little better but still lost signal. I call RV Cams back and ordered a 35' antenna extension cable. This made it possible to mount the antenna on the front cap. Since doing so both of our cameras have yet to lose the signal.
