I had a wonderful correspondence with him when I was installing my own
big stick vertical. He was kind, approachable, and helpful. We
exchanged notes and some experience data, as he was building his own,
and making up his matching units then. He comes highly recommended by
Jay Terleske of Array Solutions.
Again, you might ask DX-Engineering about its extended coax matching
stub theory. Couldn't hurt, I guess.
Good luck - I will look forward to hearing what you might do !
