Jerry,
NEMA 1 enclosures are for indoor use and most commonly come with screw
covers.
NEMA 3R enclosures are for outdoor use and come with hinged and screw
covers.
I just purchased a HoffmannR 30" x 30" x 12" NEMA 3R enclosure with
backplate and hinged cover for mounting at the base of the tower.
I agree with Roger about metal vs plastic. What size and rating are you
looking for?

NEMA boxes come in a number of models. The ones with the hinged and gasketed
door are a bit pricey, but depending on conditions, may be worth it. I
think these are the NEMA 1, while the NEMA 4 are just a box with a screw on
cover at mybe 20% the price of the model one. They are primed, come in a
variety of sizes, with a 10 X 10 X 6 being around $20 *IIRC*. A good coat
of paint and some Silastic RTV (TM) and it's one whale of a rugged box that
can be grounded.
IF you can weld and have a source for steel, it takes time along with a bit
of paint to make your own.
I stay away from plastic as I want my relay boxes grounded. All coax enters
the boxes through bulkhead connectors.

Check the less expensive NEMA boxes and see how they are priced.
Otherwise you can also use an aluminum chassis with a cover. Again, paint is
pretty important.
73 and good luck,
