    Hmmm. AFAIK, the FT-857 does not have a duplexer built in.

    You have to install an external one to use a single feedline on an ATAS-120.

    Moot point. Duplexers are about $70, triplexers are about $10 more.

    You are correct, there is a menu setting that tells the radio the ATAS 120 is being used for 1.8-440 so it will tune the antenna properly, unless the VHF/UHF is going to a separate antenna. But you do have to use a diplexer to combine them onto one coax when using the ATAS for all bands.

    I posted a WTB thread on the swamp for a VHF/UHF radio and someone locally replied. He has a Kenwood TM 733A with a Diamond duplexer for sale in original boxes. Wants $200 for the kit.

    I knew it had something to do with multiple feeds, I just didn't know exactly what it was for.

    That really is a very good price for that radio, and I believe it has cross band repeat on it which can be useful.
