That, then, is a signal strength issue. Signal strength varies with
distance between the antennas
intervening substances such as metal frames
electromagnetic
interference
signal strength
antenna orientation, and maybe something else that doesn't come to mind at the moment.
I don't know anything about your setup. Is there one or more of these that you can change to improve the tie between the two?
That must be really frustrating. All I had was my
radar popping off and making an annoying "lost signal" chime. You have your
boat going haywire.
In my case I determined that the antenna sending the radar signal to the
iPad was in the front of the dome, and that I had a grounded
aluminum frame that mounted the dome to the
mast lying directly below the antenna. Cutting it out under the dome resulted in a clearer path for the RF signal.
If my memory is right, your device is designed for fifty feet up the
mast. Can you move it closer and still get a good read on the wind? Is the mast between the two
parts? Is there metal rather than just
fiberglass between the two? Can you move the receiver so it has a better signal?
