you need to put a FM Trap / notch filter in your coax, just search google or even eBay, there are a lot of them, Good Luck.
put it between the antenna and the scanner closer to the scanner is probably best.

When electronic components are exposed to signal levels they are not designed for they will go into overload and in a non-liniar mode that makes them work as mixers. Two signals mix and creates a third signal, or several, that only exists in that component. It could be a receiver that are badly designed or use inferior components or the signal strenght are far too high.

Almost everybody will experiance an improved reception quality when using a FM trap filter.
