2 meter and 70 cm High Selectivity, High Q, Low Loss Bandpass Filters at HB9Q

144 MHz and 432 MHz Super Low Loss Bandpass Filters at HB9Q

Hi Goran.

I ordered filters because of heavy interference from the new GSM transmitter installed 120m from my 15m dish.

The filters work absolutely great for me! They clean away enough so my preamps don‘t make intermodulation!
