snippet: 5 Watt UHF Paging Transmitter Used with MLS-SPU1 Interface Unit and Optional FG4603 (3DB) EXT Antenna-INCL Power Supply. Alpha Page™ alphanumeric pocket paging systems from Alpha Communications® use the TX125-ENC paging transmitter. The TX125-ENC transmits a UHF (450-470 MHz, programmable, synthesized frequency) paging signal in the POCSAG format. POCSAG baud rates are 512/1200. RF power output is programmable to 2W or 5W. Paging range depends on building construction. Range can exceed two (2) miles (line of site). The transmitter contains a carrier detection receiver. Multiple transmitters on the same frequency can be used on a site. Each transmitter will wait until the frequency/channel is clear before transmitting. No pager database programming of the TX125-ENC is required. The MLS processor boards and/or PC software attached to the TX125-ENC provide all programming. A unity gain flexible antenna with BNC connector is included that connects directly to the transmitter. The front panel contains two (2) LED indicators (for power and data transmit). A regulated DC power supply is also included. (Page 1)
