This is the Pan Pacific UHF 7606 crimp & solder connector. These are great connectors and came highly recommended by a Ham friend. The tip is gold plated and the build is robust with good quality machining.
I buy these from HR Distributors in Portland, ME. They are located on 101 Hanover Street and they can be reached at (207) 773-2552. They will ship where ever you want and their prices are excellent.
This terminal works well with standard RG-213 but I have been told it may not fit on the Times LMR-400 coax wire. Times does make their own terminals and these may fit better than the UHF 7606.
