Rejector Unit No 1nMK2 ZA23831
 

Is there period pictures of this unit in use? Has anyone more information on this rejector books, manuals, etc.

Mainly used in command vehicles (ACV and possibly LCV) where you had multiple sets and needed to prevent breakthrough from one into the other[1].

Basically it's a tuneable notch filter, so only good for blocking a single interfering signal.[2]

There's some information (not a lot) in Wireless for the Warrior Volume 2.

Chris.
[1] e.g. keeping (or reducing) the output of your ET-4336 out of your WS19 front end. (A difficult job, given the relative power levels involved.)
[2] Modern practice is to use an "acceptor" unit ("SURF" - Selector Unit Radio Frequency) to reduce mutual interference, and low-pass filters to keep harmonics from the HF transmitter(s) out of the VHF receivers.

Thanks Chris, I was hoping for a manual or EMERs
