I spent the last 3 days building out coax runs for a couple of 10kW transmitters. The coax is 1 5/8" and 3 1/8" rigid line made of copper tubing. For most runs I used a chop saw to cut the individual inner and outer conductor, installed teflon spacers to hold the center conductor every 24" and silver plated mating contacts to mate the center conductors.
There are two runs from two 10kW transmitters through some filters, then a transfer switch we had to hang in mid air and level, then off to another transfer switch hanging in mid air off to the antenna, load, etc. All runs had to be hand cut, deburred, degreased, center conductors installed into outer conductors and accurate to within less than .050" and perfectly level. It was like building a 3 dimensional puzzle but it came out really nice.
One of the pictures shows a 1 5/8" to 3 1/8" adapter to show the size. I might have to upgrade my ham station with this stuff. The pictures are all rotated and don't want to cooperate in displaying properly.
