Please help identify what this box is
Welcome to the forum! The answer is a 4-step process. I'll do the first three, you do the last if you want.

Entering your handle &quot;IAMAW 1763&quot; in Google indicates it's a Union in Dartmouth, Nova Scotia. So maybe that's where this box is.

The box has &quot;HTC&quot; labeling. While there is a huge Chinese smartphone manufacturer called &quot;HTC&quot;, I didn't think that was the answer. So I googled HTC and Dartmouth, Nova Scotia.

There are several matches, but I rejected the Halifax Triathlon Club and further down the list found HiTech Communications (HTC) (website here). They do all kinds of communications work (asset tracking, remote internet, cell phone boosters to name a few) and I'll bet it was their device.

If you are still curious, ring'em up.
