Indeed they do Mike. I ordered a set last month, it arrived last week.
But the combiner isn't to Steve's innovative design. I'm using Steve's high
impedance amp design for my build plus the PI4CC combiner and switchbox boards.
Now Steve has put the cat among the pigeons with his new combiner design...

You can order a board set from PI4CC I think...I am not sure what they used for
the combiner circuit. A set of board for the 9 antennas, the combiner and the
switchbox was $65.00 us and they include one extra of each board.
