300 MHz frequency range was always noted for its specificity, for exact 25 kHz frequency grid pitch in particular. This was connected with division into "trunks" in "Altay" system. River craft radio stations use equipment with the same repetition factor, also. Demand for communication channels, growing every year, mostly satisfied by this particular range usage. Transmitter combiners CH-4(2)A-50S(D) occurs to be the most successful solution for constructing multichannel system, operating with common antenna, in this case. Together with antenna DS8-ALT, duplexer DPF4-4A, receiver distribution panel PRP-2(4)A CH-4(2)A-50S(D) will represent complete solution for your antenna-feeder system.
Hybrid transmitter combiners are designed for mounting in standard 19-inch rack.
Manufacturer adjusts transmitter combiner to customers operating frequencies.
