  1. I don’t see why you couldn’t. Don’t know how big the box would have to be though. Also Make sure it is a DPDT heavy duty rotary switch that can take some high power.


  2. Thanks for sharing, I wonder if I could build several band-specific filters and with switches select which band I am ‘passing’?

    I’m imagining a rotary switch that selects which filter goes in-line, thus avoiding a coax switch or two with the filters and two coax jumpers per filtered band. Ideally a double-banked switch would be ideal – simultaneously connecting the input and output to the coax in/out connections.
