Attenuators - Interconnects PADS BNC 50 OHM BNC(M) (F) 10 db (1 piece)

If you are buying this for the Fail-Safe Long Range FM Transmitter - FS CZH-05B forget it - the FS antenna is threaded so you would need an attenuator which is threaded on both ends (whatever size the FS thread is, didn't measure it) and good luck finding that......Otherwise it's probably a great attenuator.

You can certainly buy much more expensive units, but I do not see any difference in the quality for what I do.

A little tight fitting but ok.
