A good low loss way to use one feedline for up to 6 bands is a 6 position
SMA relays. Use 2, one at the antenna and one in the shack. Keep in mind
they have a max power rating. But they will easily handle 1296 and higher
some up to 18ghz.
Almost no loss below 432.
There available in 24/28vdc and 12vdc. You just need a 6 position switch to
controll them.
Here is a link to some sma relays>>

You can also use the 6 pos switch to control the ptt on the rigs so you dont
accidently transmit into an unswitched port.
