For what it's worth, I had an Ameritron RCS-8 at the base of my tower
for 21 years with no protective box. I *was* careful to waterproof the
coax connectors, but nothing special, just electrical tape. The tower
was in a medium-dense woods, so not exposed to heavy wind, but it looked
like new when I took everything down.

The gland of a cable gland is a form of packing gland. A cable gland
for coax will have a relatively soft rubber insert through which the
cable (coax or whatever)) is passed and then compressed to attain a
weather tight seal. A threaded portion of the fitting is screwed down
to compress the soft rubber insert.

Thank you for your reply.
I appreciate knowing the source and the term, ‘cable glands.’
The measurements were rough, but since the Ameritron Antenna Switch
will reside in the box and both box and the switch will be attached
to the 45G tower leg, I need some space to accomplish that.

G’day all;
After many years/decades of minimal amateur radio work, I finally
have a tower with rotor and beam, dipole and vertical. I finally
installed a five position remote coax switch. I would like to
weatherproof the assembly by enclosing it in a weather tight
case. The case or enclosure could be found at the local big box
store or electrical contractor’s supply store, which should
measure; Width = 10”, Depth = 9” and Height = 12”.
If you have a great suggestion for suppliers, please let me know.
What you are looking for is often called a "Hoffman box" (Hoffman
is a major manufacturer of such things). Generically what you're
looking for is probably a "raintight enclosure" (NEMA 3R).
They're available in plastic as well.
With or without a panel that mounts in the back (so you can
assemble your stuff on the panel, and then it mounts on pressed or
welded in standoffs inside the box.
Your sort of size is pretty common - it's used for things like
Cable TV and such. You might find something at L-com.com
http://www.l-com.com/nema-enclosures?cmp=LM1
9" might be deep for a 12x10 box
Plus: I am at a loss for the weatherproof pass-throughs for the
RFC 600 & RG 8 coax. Believe there was a distant discussion for
such items.
There are a variety of ways to do this.. there's "cable glands"
which provide a weather tight seal around a cable, but you probably
won't get the coax connector through.
You could use bulkhead feedthroughs, connector on the inside,
connector on the outside. Or jumper cable with a jack on one end
that mounts through the box wall and plug on the other end to
connect to your relay.
Thank you for the suggestions.
