Microwave Filter Co. 10717A VHF tunable bandpass filter 116 - 150 MHz Perfect for ATC monitoring and 2m DX The filter will actually tune from 95MHz to about 193MHz  Excellent mechanical cavity bandpass filter with superior rejection as can be seen in the tracking generator photos (I am using a 20dB pad on the input) insertion loss is about 3dB, not a big deal considering the benefits of nearly silencing everything  outside the tuned frequency. a good 10-20dB receive LNA preamp after the filter will increase the receiver sensitivity without overloading the preamp or receiver with strong interfering signals.  I am using a few of those successfully connected to one receive ATC antenna and feeding a few receivers simultaneously,  some with and some without preamps. I use AOR receivers and a few RTL-SDR's with great results, nice, clean and interference free. This filter is built extremely well in the USA ! in fact, it's mechanical stability and excellent performance made it the filter of choice for ATC and FAA equipment,  including two which I own and can testify to their solid performance: Motorola / General Dynamics CM200 ATC radios.   Filter is rated at 15W transmit power, which makes it suitable for transmit applications as well,  such as DIY and off-the-shelve LPFM transmitters (most are harmonics rich and have very little filtering) I will tune this filter to your frequency free of charge and on demand.  Thanks for watching this item, Please check my 100% feedback  and bid with confidence ! 73's , N2BM
