I want to hang an antenna in the attic for a mobile I'll get that will be 2m/440 and I'd like to use the same antenna for my scanner. Basically want to run one coax through wall. I've been looking at duplexers and the concept seems like it would work but with them being for specific bands that would be the issue with them. Anyone know of a duplexer with wider bands like one for 2m/440 and the other for all to run to my scanner? Or is there something other than a duplexer that would work?
