For the operation of repeaters in low-frequency range VHF we have developed and launched the manufacturing of a duplexer on the spiral resonators. Two model of duplexers are being produced: MDF-6LB(M) - for the range 37-44 MHz and MDF-6LB(H) - for the upper range 42,5-50 MHz. With the separation of 3-4-MHz they provide a fully-duplex mode of operation of mobile radio stations at minimum losses and standard output power 150 Wt.
This construction is significantly less in sizes than the fully-sized duplexer made on the basis of of the volume resonators. The duplexer MDF-6LB is recommended to be used jointly with our new antenna GPW-1LB.
