[TowerTalk] PL259 Connectors Part 2

[Tim Duffy]

Hello Jim:

As you reported - W3LPL and K3LR (and many others) are using this method
with the Amphenol 83-1SP of soldering the shield on the back of the
connector. It works great. 

http://www.k3lr.com/engineering/pl259/


No melted dielectric and very visible great soldered connection of the
shield. No failures here at the K3LR multi multi station in over 30 years -
and the contest station success efforts - show good results.

Hope to see you in Dayton

A properly installed soldered Amphenol 83-1SP makes a pretty strong 
connection to the coax. "Properly installed" includes stripping just 
enough braid so that it shows through the solder holes and so that the 
coax jacket screws into the connector shell, soldering the braid at each 
hole so that it flows well, and doing a good soldering job on the center 
conductor. Many times, I've had to yank pretty hard on the RG11 attached 
to high dipoles to guide them away from tree limbs, etc. So far, I've 
never had one pull apart.

K3LR has developed a method of soldering the braid to the OUTSIDE of the 
connector shell and covering it with heat shrink. That's probably even 
stronger!  I've done that with a few connectors, but wasn't thrilled 
with the result. QST published it a few years ago, and I think it's 
somewhere on the internet.
