Re: [Moon-net] WX sealed box for Coax Relay
I copied the AMSAT-BB with this as sometimes a hint or kink is passed on to all.
You can use an old seaman's type of drain hole hint. If the hole is about 1/4" or so, get a piece of string and put a large knot on one end, pass it through the hole and add another large knot with about an inch or so protruding. As the wind blows, it knocks the string around and assists the draining. I used it in many a situation with tuners and couplers and even in satcom domes. The string acts as a deterrent to things going in and clears the hole when the wind blows. Hope this helps... 73, Dee, NB2F

Some way must be found to plug the drain holes in such a way that lets the moisture in and out, and keeps the insects out. You really do not want to open the box and find a Wasp nest.

Hi Dee, NB2F
The solution that you propose is the best one I have seen to drain water, umidity and moisture out of a relay or preamplifier box. The wind act as a pump,simple and effective.
