[amsat-bb] Question about duplexers/diplexers

[Mark Lunday]

I want to use a single coax for three rigs, feeding to three antennas.


Rig 1 = 6 meters
Rig 2 = 2 meters
Rig 3 = 70 cm

Each has its own antenna at the remote tower.

Question #1: I should use a triplexer at the shack where the three antennas
combine to the single coax, and a triplexer at the antenna where the three
antennas are located.  Correct?
Question #2: any recommendations on which is best?  I was looking at the
Comet CFX5140
Question #3: can I run 12V through it to power my mast-mount preamps at the
tower?
