Any opinions on tri-band (2/220/440) antennas?

[Bill Newkirk]

got a school station to set up - and have only one run of coax to the roof
available for VHF/UHF. was thinking along the lines of something like
a comet cx-333 or a discone.

would like it to be able to take a salt environment pretty well (it's on the
beach).

would like to include these three bands since that's the 3 big ones for people
to use and don't have any 6m gear coming up in the future...

needs to be mechanically well built.

i'm open for suggestions...tnx es 73

In regards to the CX-333: When it was still a new model I knew of one
where the owner was less than pleased with its overall perfomance.
Recently I bought a CX-333 and put it on a remote base for 144/220/440. I
works better than the compromise of two separate antennas that I had
before and takes only one run of hardline. On 222 it works just as well if
not better than the Comet 220 mono band base antenna. On the 144 side the
remote base does a bit better than the 220 repeater at the same site that
is 30 feet further up the tower (not terribly surprising, but the triband
antenna does do well.)

I can't give a more scientific answer, but I have been pleased with my
CX-333. Please make sure that you use a good grade of coax for that single
run in your project.

Have fun!
