[TowerTalk] DIN to coax connector?

[Jim Brown]

Yes, sort of, but you have to have seen one to recognize it. :) It's a 
two-piece connector, and both connections are soldered to the part that 
attaches to the cable. The second part screws onto the first part after 
it's been soldered. In the photo in the link below

The second part is at the center of the top of the photo, the first part 
is right next to it on the left (with an integral hex nut to facilitate 
tightening the two pieces. There are two solder holes for the shield and 
one for the center conductor. Neither are visible in the photo.

After studying their webpage, I think that their UHF and F connectors 
are pretty conventional. But the N-connector is really something 
special. I've used it with a cable having a #10 solid center and shield 
diameter comparable to most RG8/213 and it fits quite nicely.

This company is basically a machine shop and was owned by a guy named 
Andros who was a ham. I spoke with him on the phone roughly five years 
ago when I found some of his connectors in the stash of an SK whose 
stuff I was helping his XYL turn into cash.  I bought at least a dozen, 
maybe more, for my stash.  A year or two ago, I called again and his son 
was running the place. I didn't ask about his dad. I should have. Names 
on the "contact us" page are different, so perhaps the biz has changed 
hands.
