UHF Diversity Multicoupler

Rio Rancho, NM 5

Antenna Input

Standard 50 ohm BNC connectors are used for the an-

tenna inputs and signal distribution. The RF signals are

fed to the receivers via coaxial cables that loop through

the front panel to the receiver inputs. The leads are

labeled as “A” and “B” and routed so that each receiver

has one of each connected for diversity reception.

Power Supply

The multi-coupler is powered by external 12 VDC (11 to

18 VDC is acceptable). The center pin of the input jack

is positive. The power supply must be capable of han-

dling up to 2 amps of current. DC power is distributed to

the receivers via rear panel pigtail connectors.
