A really nice FM band reject filter
I needed an FM band reject filter for making spurious and harmonic spectrum analyzer measurements for a broadcast transmitter in the FM band and this filter does just that. The attenuation from 88 to 108 MHz is more than 50 dB as measured on my network analyzer (53.4 dB at 88 MHz and 56.4 dB at 108 MHz). If you were to use this filter with an aircraft band radio receiver, it will attenuate the lower part of the band (118 to 124) to some degree, so that it may not be useful for that application. It would have been nice if the top end of the reject response were a little lower in the FM band. The filter appears to be a very well built device mounted inside of a metal box with female SMA connectors. Also supplied is a double male SMA adapter, and the price, as delivered, is quite ...

It is useful
It is useful for RTL-SDR dongle. It helps listening VHF, UHF and airband with RTL-SDR. It is reducing effect of FM broadcast stations on VHF, UHF and airband. You can see screen shots of SDRsharp with and without filter. I can hear airband as same as my professional receiver after put it between antenna and my RTL-SDR dongle. Thank you producer. You can also use it as a frame of your custom filter design. Remove SMD components and put your own on it. It is useful for RTL-SDR dongle. It helps listening VHF, UHF and airband with RTL-SDR.

Improves across the entire spectrum when scanning with AirspyR2
Using the Airspy R2 near a FM-radio broadcast antenna, I had lots of interference from FM-radio signals. The CB-band had large spikes all over it. The airband had large spikes all over it. On many different places, across the entire receivable spectrum, the FM-spikes would show. The FM-filter is very efficient and has opened up the bands that were previously closed. It begins a slow fade from full-pass at 80 MHz to max-stop at 84 MHz. Continues max-stop to 114 MHz and is back up to full-pass at 118 MHz. So max-stop is between 84-114 MHz, although the filter has a dampening effect from 80-118 MHz. It has no ill-effects on the reception of airband-communication (But the nav-part of the airband is obviously affected (But no talk is at that band, so that shouldn't matter to many) The ...

Works great :) JEL

It works
It did do the job I wanted..., its very strange because all the high power FM stations are over 5 miles away, BUT I have a lot of receiver overload around the VHF bands like 2 meter ham, I have had this problem with several different SDR receivers and just plan scanners radios, when connected to outside antennas. total de-sense , swamping front end, by the FM broadcasters this little filter took care of the problems, It did do the job I wanted..., its very strange because all the high power FM stations are over 5 miles away, BUT I have a lot of receiver overload around the VHF bands like 2 meter ham, I have had this problem with several different SDR receivers and just plan scanners radios, when connected to outside antennas. total de-sense , swamping front end, by the FM broadcasters this little filter took care of the problems,

Great value & price
I have used this with two of my receivers and this filter works fine with both of them. The other one had strong FM band signals on 70 Mhz and the other one above 180 Mhz and now all FM band ghost signals are gone. Still leaves real signals left. Good cabinet.
