PAR Electronics seems to have some great filters for scanner enthusiasts.


Their VHF-FM filter will probably benefit airband listeners.  It notches the FM broadcast band (88-108 MHz), which is often a source of trouble for airband listeners who live close to high-power FM radio stations.

From their catalog:

"The VHF-FM filter is a classical 3 pole filter designed to substantially reduce signals from the FM broadcast band by a minimum of –25 dB and a maximum of –50dB. A 10 turn precision piston capacitor allows the end user to custom tune one of the notches ( it is factory preset at 98 MHz). Loss at 116 MHz is only –3dB, dropping rapidly from there to only -1.7 dB at 120 MHz."

Universal Radio carries this filter for $66.95 (Order #0098).

There is also the BCST-HPF for those experiencing interference from AM broadcast stations.  It passes 1.8-200 MHz and notches out 0-1.7 MHz.


Universal Radio has it for $48.95.  Order #4426

If you don't hear radio stations on your feed or on your scanner while listening to airband, you probably do not need one of these.

This filter looks pretty cool too. http://www.universal-radio.com/catalog/filters/0880.html .

Also, this one blocks out:
FM Broadcast Band 88-108MHz,
Paging Frequencies around153MHz,
Shortwave, PMR, etc.
