Hi All,

Is it worth using a duplexer with individual antennas for 2m/70cm versus a good dual band antenna?  73, JC

IMHO, no.  A good dual band antenna can do as well as a single band antenna.  In fact, a good triband antenna (mine covers 2m, 222, and 440) can also work brilliantly.

A diplexer often costs more than a dual band antenna, plus you still need to buy two antennas, and run two coax lines.  No clear advantage to doing it unless you have a specific purpose in mind.

depends on what you need.

Sometimes, a dual band antenna just will not work as well as two (or more) 1/4wave antennas. If you live in the mountains, a 1/4 is better than a 5/8 wave. If you are a flatlander, a 5/8wave is better than a 1/4wave.

If you need to run an amp, then you may want to run monoband antennas.

If you do not have the space on the car, then a dualband is a good compromise.
