Hello,

Have a scanner in which I listen from 25 MHz or so up thru the vhf and uhf
scanner frequencies of 1.3 GHz.
Presently, one desktop scanner connected full time to one Scantenna in
attic.

Will be buying a handheld scanner, which I will be using (when not being
used in a mobile mode) in probably one of three other rooms in house.

I would like to connect a new antenna in the attic also, but have coax
brought split out to the three rooms
as ports for the handheld to be plugged into.

Only one of the three ports will ever be used at any time.

a. Do I need a "Coupler" between the three branches from the new antenna's
feed ?

b. If not, will the two Unused ports need to be terminated, or is just
hanging open fine ?

c. Anything else I should probably be asking about this proposed setup ?

Thanks,
Bob
