EMR Multicoupler and Preselector, 138-225 MHz, 3-4 Channels, 3-8 MHz Bandwidth, N Female (Ant.) / BNC Female (Outputs).

EMR Multicoupler and Preselector, 138-225 MHz, 3-4 Channels, 3-8 MHz Bandwidth, N Female (Ant.) / BNC Female (Outputs).

Multicoupler with Preselector 138-225 MHz, for 19 in. Rack.

It applies only to signal reception whose operating principle is based on the collection of the external signal through the antenna that is connected to the PRESELECTOR which is a Passive Band-Pass filter adjustable in a bandwidth of 3 to 8 MHz within the frequency range of 138 to 225 MHz, to subsequently interconnect to the MULTICOUPLER which is made up of a 20 dB gain Pre-Amplifier, externally powered by 115 Vac. whose operating polarization is 13.6 Vdc. complemented in the final stage by a passive power divider with 1 to 4 outputs, available to provide the signal to 3 or 4 Receivers, generally RF Repeaters.
