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.

The Lectrosonics PS70 is a switching power supply with
coaxial connector matched to the 12VDC power jack
on the multicoupler. The AC receptacle is a standard,
grounded IEC 60320 C14 inlet socket that will accept
common cords like those used on computer equipment
(AC cord is not included). Output cable is 6 ft. long.
