Type 7-373 Diplexer 30 MHz - 162.1 MHz / 225 MHz - 410MHz 7-373-DS Issue 1 The most important thing we build is trust
The 7-373 diplexer operates over the frequency ranges 30 MHz to 162.1 MHz and 225 MHz to 410 MHz. The diplexer comprises a low pass and a high pass filter connected in parallel at the input terminal. The electrical assembly is housed in a machined, aluminium alloy box, enclosed by an aluminium alloy baseplate. Three mounting holes provide for attachment to the mounting surface.
