The Comet CF-706N duplexer is designed to handle transmitting and receiving frequencies of 1.3/57 & 75/550Mhz simultaneously. It features a high-quality filter system to prevent TVI and offers more than 45dB isolation between the two connectors. The bandpass frequencies and input loss are impressive, with less than 0.4dB for both ranges: 1.3 - 56 MHz and 75 - 550 MHz. The impedance is 50 Ohms, VSWR is less than 1:1.2, and it weighs 300g with dimensions of 66w x 90d x 26h mm.

For optimal performance, the CF-706N is equipped with an input socket of SO239 type and output leads with 1 x PL259 fitted and 1 x N-type plug fitted. It can handle a maximum input power of 350 Watts (PEP) for both frequency ranges: 1.3 - 57 Mhz and 75 - 550 MHz. When using the CF-706 for one frequency, the other connector can be left open, although using an additional dummy load is recommended for better results.
