Wideband Antenna Multi-Coupler (1-In/4-Out)


The PS 4000 multi-coupler combines an antenna splitter and dc power distribution in a chassis that is one EIA standard rack unit high and one-half rack unit wide in a full metal housing. Thus, two multi-coupler units can be placed side by side (Rack Mount hardware kit included) or one PS 4000 side-by-side with e.g. an SR 4000 receiver unit.

The PS 4000 has a wide-band antenna signal amplifier/divider with a 220 MHz-wide UHF bandwidth, making it suitable for all available WMS 4000 channels. The multi-coupler provides 2 BNC antenna inputs. The incoming diversity signal is internally amplified and divided to 4 pairs of diversity outputs, thus the splitter provides 2 x 4 BNC antenna output connectors. Two additional BNC outputs are available on the rear panel for cascading the diversity antenna signal to another multi-coupler. Up to 3 multi-couplers can be cascaded to supply antenna signal to 12 receivers from a single pair of antennas.

The PS 4000 offers the following displays: one blue LED indicator for each antenna input showing that the connected cables, signal amplifier and antennas are fully operational. A red LED indicator will indicate a failure, like a short or loss of power.

A 3 bit dip-switch for compensation of the connected cable length is available on the front panel to optimize the system's performance. On the rear panel of the PS 4000, a DC input can be hooked to either a single PSU 01/4000 or to the optional PSU 4000 central power supply unit, which can be connected to power the antenna splitter and the connected receivers and antennas remotely via the antenna cables.
