[TowerTalk] DIN to coax connector?

[Kelly Taylor]

Far be it for me to argue with someone in the industry, but…

The DIN install videos I’ve seen suggest the centre conductor is soldered into a shallow well inside the connector, almost the way a conductor would be soldered to the well inside a chassis-mount SO-239. Considering the centre conductor of a PL-259 passes through to the end of the connector and is soldered there, with perhaps a greater degree of conductor-solder-connector contact to grip the conductor, and given the crimp-and-solder style PL-259s employ a similar clamping scheme to DINs, I’m just curious about the statement regarding mechanical superiority.

It seems the centre conductor might be the weak link. Can you clarify, Steve?

As for the crimp-crimp style PL-259s, is there a valid reason the instrux typically warn against soldering the centre conductor? 

73, kelly, ve4xt,
