They use one shelf I'd cut and finished four or five years ago and about given up on installing, plus a long one I had used in the kitchen of my previous house:
Vertical supports are just pipe flanges and precut pipe sections. You can buy flanges really inexpensively online, but the quality isn't great; some castings weren't square to the tapped hole and some needed to have the mounting-screw holes drilled out. 1/4"-20 carriage bolts hold them to the shelves. If I had used the same size pipe for each level, the flanges could have been back to back
The table was from one of the big chain stores, an inexpensive Mission-style side table.
Equipment in the picture includes a big RME-45 receiver, a Multi-Elmac AF-68 transmitter, and a Millen transmatch, with a homebrew antenna switch, a Ten-Tec transmatch and an RME VHF converter
