2m 70cm High Power Diplexer 750W 144-148MHz 430-450MHz

2m 70cm High Power Diplexer 750W 144-148MHz 430-450MHz is a bidirectional device that can be used to simultaneously connect two 2m and 70cm transceivers on one single connector dual-band antenna. Or to combine a dual-band two-connector antenna or two antennas for 2m and 70cm and use a single coaxial cable carrying a combined VHF / UHF signal into a dual-band transceiver with one antenna connector.

With two diplexers, one at the transceiver’s end and the other at the two antennas ends you can lead a single coaxial cable to get into your station. One diplexer will combine two antennas the other will split signals into two transceivers.

Super low insertion loss on 2m 70cm High Power Diplexer 750W has been achieved thanks to the use of high Q capacitors and inductors on Rogers laminates. Ultimate low crosstalk of -75dB is achieved due to the use of the extraordinary design of filters.
