[TowerTalk] DIN to coax connector?

[Bob K6UJ]

Steve,

Whats your opinion on this 7/16 DIN connector for 7/8" line ?
Is this similar to the ones commonly used at cell sites, etc.  ?
I would use this guy on RFS Cellflex LCF78-50. (7/8")

I am trying to find a video on you tube or something showing the
installation of the 7/8" DIN's.
Is this video a good idea of the assembly ?
Know of another video for a newbie ? :-)
