[TowerTalk] Tower-mounted enclosure

[Pete Smith]

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.
