Having interference issues on UHF? Check out the following:

DCI UHF 10 MHz Wide 4 Pole Bandpass Filter (Model: DCI-435-10C)

UHF 10 MHz Wide 4 Pole Bandpass Filter (430 - 440 MHz)

Ideal for US Satellite and weak signal

The design for this bandpass filter is four full quarter-wave linear resonators with aperture coupling. It comes with silver-Teflon - gold "N" connectors.

The filters are the same height and width as the VHF models but are slightly heavier and deeper.

The DCI-435-10C is used in European-Asian ITU Regions 1 and 3, and is also used in North America for weak signal, packet and other specialized communications.

Connector Type: "N" silver-Teflon - gold
