Diplexer 

20-512 MHz Series II Diplexer (1Y05400)

The Series II Diplexer is part of our Series II Communications Platform, but can be used separately to isolate a 20-88 MHz (low band) antenna from a 113-512 MHz (high band) antenna. It can also be used to feed two antenna outputs into a single radio input.
The Series II Diplexer adds very little loss (less than 1/4 dB at most frequencies) while providing excellent isolation (as much as 60 dB)
