My reception is much poor on the spyder than the wing.
It's J&M. Good quality stuff.
Our club has both wings and Spyders. At least two of the spyders have "factory" CBs and next week mine will be #3.
In our experience, the Spyders have been as good or better than the wings and the few handlebar mount J&Ms that are present.
Last time I had a static problem, it was because my antenna was loose in the mount.
The time before that, there was a bad connection in one of the headset cords (contact cleaner for that).
You need to trace out the coax that goes from the radio head to the antenna and check/reseat any of the screw type connectors in the line. Also check the connection at the base of the antenna.
CALL your dealer and see what they have to say. Maybe they know of a shop.....or maybe the DO know enough to trouble shoot the problem.
Are there any truck stops in your area ??
They can often point you to a CB shop in the area.
HAM radio operators can be helpful too as a last resort.
I'm too far away to be helpful.
