loose signal within 500ft have a range extender P3S

I keep loosing the signal to my p3s. Sometimes happens within 100ft of home. Cant ever get beyond 500ft. Red error message returning home. I have a range extender on the antenna. I used to get out at least 1000ft. Happens at all altitudes. It will regain a signal but I have to do a lot of movements .
Any suggestions on where to look or what to try?

Which range extender are you using? Did this problem start occurring before or after you installed the range extender? Did you drop or damage your remote controller is some other way?

What he said. More info needed.

Which range extender?
