Roy:

You will find that a yellow Prestone anti-freeze bottle will last at least 5
years, and likely 10. We get plenty of UV here in S. Texas, and I have
found them to have the highest survivability of any plastic except Lexan.
My 160 meter tuner is in one, as I didn't want to use a small coil or a
large metallic enclosure. I use 2, cut the top off of one and invert it,
and then use the inverted bottom from another as a press fit closure. No
fasteners needed, although I usually put a couple 6-32 screws through the
resulting double flange for good measure. The old red bottles were equally
as good, but now hard to find.


And for Ken, the best way to seal the end of that psuedo air line is some of
the shrink tubing with the filler adhesive inside. Then point the sealed
end DOWN.

In that case, I have yet another caution. A tupperware container will
become brittle from exposure to the sun, and crack. How long this takes
depends on the intensity of the sun. Here in Oregon's Willamette Valley,
it'll last a couple of years or so. I'll bet one wouldn't last six
months in Denver.

I'm right now in the process of accumulating parts to rebuild my antenna
switch box, formerly housed in plastic containers, into an ammo box.

You might be able to seal the cable end adequately with RTV. I'll bet
some of the folks who've used Belden 9913 (similar construction to
RG-62) have some suggestions. It's been discussed from time to time on
this newsgroup, so a google search on 9913 in this group would bring you
more information.

Thanks Roy, I planned on using a small tupperware container at the

antenna
end.
