Considering one of the little "brick" amps to pump up my handheld.
Stupid noob question:
Do these units pass the signal through un-amplified when switched off?

thanks.

Usually they pass through when off, but you'd have to check the specs on the particular amplifier you're considering.  If you have a dual band handheld, 2m and 440 for example, and try to transmit on 440 while connected to a 2m brick amplifier, you may find nothing comes out the amplifier.

MFJ makes a small (35W I think) amplifier that is dual band (2m/440) that does pass signals when off.

I have several , in the 160 to 400 watt range on my mobiles in the shack, on 2m/440/6m/220 mhz and they all pass through when off. but these are all single banders. I would say that they all pretty much should have to pass through when off
