Antenna-Feeder System Set for Efficient Radio Transmission (PAFS)

The product is designed for operation with a radio transmitting device (RTD) with power up to 1 kW in continuous mode in the frequency range from 1.5 to 30 MHz and to provide radio communication on the routes of small and medium length. The product contains: a frame antenna of zenith radiation with a matching unit (SU), control unit (CU), cables, mounting kit and a set of packages. CU is a device which is installed in the control room and provides interfacing of the product by control and monitoring commands with the RPDU and communication complex, implements the algorithm of switching the operating frequency, provides the possibility of manual switching.

The directional pattern (DN) in the horizontal plane is non-directional, the maximum of the directional pattern is oriented to the zenith. The product provides tuning to any frequency of the operating range with travelling wave coefficient (TWC) not worse than 0.25. Permissible power of the RTWR: nominal - up to 1.0 kW and maximum - up to 1.2 kW (at the carrier frequency).
