I'm sure I'll be roundly criticized for this, but my entire antenna switching
system for one-tower SO2R - 8 relay boxes in total) is enclosed in a $5 plastic
under-bed storage box. I mounted all the relay boxes to a sheet of aluminum
and used a couple of cut down u-bolts to hang it on a tower cross-member. The
top snaps on neatly, and I bring all the cabling out through the bottom. Made
no effort to seal around the cables, and am watching it carefully, but so far
so good. Beats the heck out of a $100 enclosure, even though I may have to
replace it every year or two because of UV.
