Achieved results on a built Band pass filter:

50 MHz = -68.4 dB
88 MHz = -45.6 dB
108 MHz = -31.5 dB
144 MHz = -0.21 dB
146 MHz = -0.21 dB
432 MHz = -75 dB
These excellent results were achieved by careful selection of components and design of the filter. This type of filter is necessary when you have near by strong 50 MHz, 432 MHz station or FM transmitter (88 - 108 MHz).
