RX MULTI COUPLER

RX Multi coupler is a device that uses a single antenna to simultaneously receive signals from multiple channels and distribute the signals to each receiver. It mainly includes; Isolators, wideband low-noise amplifiers, filters and multi-channel distributors. The distributor is equipped with a built-in receiving signal amplifier to compensate for the losses in the antenna feed system.

Characteristics

Purchase low-loss cavity filters to increase out-of-band suppression and isolation.

The modular design makes maintenance convenient

Optimize the noise coefficient without affecting the bottom noise of the base station.

Select and configure the software monitoring version

Optional screen and indicator lights are available to display the device status

Supports systems such as DMR, DPMR, P25, and PDT
