Radio Shack, before their bankruptcy, carried one. You might contact any remaining local stores and see if they still stock it. Catalog # 15-0024. Other than that, there are no retailers that carry one.

The FM filter almost always goes before the first amplifier.

The Radio Shack FM filter is not suitable for your location. It will not attenuate WFDD on 88.5 MHz because it is designed to allow reception of CH 6 TV. It does well at the high end.

The Antennas Direct FM filter is just the opposite. It does well at the low 88 MHz end but not as well at the 108 MHz end.



The MCM does well at both ends.



You can use a HLSJ as an FM filter. It has low loss and attenuates everything below TV CH7 including the FM band.

The Xtreme Signal HBD8X can replace BOTH and do it with ONE coax feed and it's only $49.95 at Solid Signal

It can pick up from two different directions
