Hi all,


Ray, N6HE here. My radio club plans on going to activate Santa Catalina
Island (IOTA NA066) again in February 2017. In the past we've had problems
with 2 radios simultaneously on 20/17, 17/15, 20/15, etc. We don't have the
room to be completely "tip-to-tip" with our 2 hexes, nor can we get much
physical separation between the 2 antennas for the 2 rigs. So - problems.


Now I'm thinking that the "Triplexer + Bandpass Filters" idea with only one
hex antenna might be the answer. I hear reports that this approach works
well, but I'm totally chicken to try 2 of my radios transmitting into one
antenna (or more accurately, 1 transmitting and 1 receiving) at the same
time. Jeez - 100W that close to a receiver's input???? Nice theory!


So my question to the group is "Have you had personal experience with this
setup AND does it work as advertised?" I see triplexers from Dunestar and
Low Band Systems (with the associated bandpass filters) - we'd be on 2 of
20-17-15-12-10M at the same time.


Your thoughts?


Thanks in advance,

Ray N6HE
