I have a Woody's fairing with an Infinity PV-250 radio that Glenn was good enough to install for me. It has a wire antenna looped around inside the fairing. AM comes in fine, but FM reception is weak. Is there any type of booster, or different antenna that might aid reception?

I have no problem with the wire atenna that came with my woody’s. But they do make a booster you can add in.

Dakota Digital offered one (which I have in my custom I/S's fairing) and IIRC Sierra sells a booster too.

We have a few good custom radio-stereo shops. I stopped in one day and got a lot of good information and advice from them.

Thanks for the suggestions. I have discovered the problem, now to find a fix.
As it turns out, the reception is fine unless I turn on my LED driving lights. Seems there is some noise or interference.
I am guessing there is some way to shield the cable to prevent. Next time I have the tank off, I will get to the wiring. Maybe I can simply re-route away from the radio wiring.
Any thoughts about cable shielding would be appreciated.

Go on amazon and order rfi chokes. They will clip on you led wiring and iliminate the interference.
I put those on my led headlights and got rid of all the interference.

A common-mode ground loop will cause this problem.
The root cause, though, is the LED driver. They're pulse-width-modulated, in order to keep the average power going to the LEDs within limits...but the waveform is a square wave and is rich in RF harmonics.
Best thing you can do is to choke the heck out of any leads going to the lamp assemblies (as a previous poster pointed out) and look at using a single-point ground system for all the electrics. This includes the antenna booster (if installed). There's really nothing you can do to the "output" side of the LED controller to kill the noise without affecting the circuit operation.

if your led's have a module in line like my headlights did. i put a choke on each side of that black box module.
