This DCI -146H 4 Mhz Wide 2M Intermod Bandpass Filter can be used to reject out of band commercial signals, to reduce intermodulation in either base or mobile 2 M transceiver receivers. Great if you are close to commercial VHF repeaters, VHF pagers on hilltops or high office towers, where your 2 M radio picks up these signals in addition to the 2M signal you are trying to receive. Can pass up to around 200 W of transmitter power in the whole 2M band. Comes with 2 UHF type female connectors to install between the 2M  transceiver and antenna and covers from 144-148 MHz of the 2M band. 

$125 plus shipping cost
