Is it OK to get some kind of storage container or something like that and
put my duplexer outside? What would be the risks of doing so? I am in
Florida so lots of rain and heat but no freezing months or anything like
that?
Thanks,

I would think that at the least you would want to build a small building, even
something close to a large dog house, 3'D X 4'W x 4'H. Leaves at least a
little room to breath and work around, heat may be a factor depending on the
cans you use and may send them a bit out of tune from the

Sounds to me like the cans are tuned backwards, meaning, you are trying to pass
low/notch high on the pass high/notch low sides.

That deck box would work. If I laid it down. I actually have a nice
storage cabinet in my shed that if I put the stuff in it onto shelves I
could have room for the duplexer and some other storage above it. Shelves
are probably cheaper than the cabinet.

Could be a couple of things going here but your description of your
tuning procedure has me concerned. Even at 10 watts power, it is
quite possible to damage cavities due to the voltages produced.

Without measuring the rejection at whatever offset (12 MHz, 25 MHz, etc.)
they would be used at, it's hard to say whether or not two pass cavities on
each side would afford enough isolation.
Jeff and Chuck,
Thanks for the replies. Not being familiar with the aluminum stock
method, I'll give that some more thought. I'll see what Home Depot has
to offer. I think I might have a blank rack panel to cut so I'll give
that a shot too.
