INTRODUCTION The UTX1KW-A transmitter was designed to meet or exceed all FCC applicable specifications for TV Broadcast Equipment. Special attention was given to the selection of sub-assemblies and components to achieve maximum reliability and minimum down time. The construction of the UTX1KW-A is BASIC and MODULAR with most components field replaceable.

The UTX1KW-A transmitter was designed to accept 208 to 240 V AC using a four (4) wire connection. The four wires are: • 2 wires for 208-240 V AC • 1 wire for neutral connection • 1 wire for safety ground connection CAUTION: Connection to the AC Primary Source must be made using all four wires listed above.

Provides a HIGH ANTENNA VSWR MONITOR in the event of an antenna or coax failure where the reflected power exceeds 25% the transmitter will shutdown. Front panel LED will change from green to red in case of a fault. 4. Provides current monitoring of all the pallets used in the two U600LDV2 power amplifier assemblies.

DC40-1KW DUAL DIRECTIONAL COUPLER The DC40-1KW is a dual directional coupler used to sample output forward and reflected power. This signal is applied to the ADP1000 and is used to indicate forward and reflected power levels. This is a closed unit and cannot be serviced. In the event of a failure, call the factory and request a replacement using P/N DC40-1KW.
