Why? Are all your systems at UHF?

##  7-16 dins are the bomb.  Andrew stopped making UHF connectors for 
7/8 inch heliax years ago.  No way in hell would I invest in an N connector for
the larger coax cables.   We used type N on several cell sites at the telco I worked
at. Coffee mug sized connector..with this tiny puny pin, that is identical to a BNC
pin.... on the end of a piece of 1.250 inch heliax.   The new standard is 7-16 dins,
which at the time, were barely any more $ than a type N connector. 

##  7-16 dins have a massive center pin, yet the chassis connector flange is only
1.25 inch x 1.25 inch, barely any bigger than the 1 x 1 inch flange on a UHF female 
chassis connector. 

##  Type N is good till aprx 12 ghz.   7-16 dins are good to 6-7 ghz.... moot point.

##  On the 7/8 inch  and up cables, whether  heliax or stuff like LMR-1200DB, they only offer 
2 types of connectors,  type N..and  7-16 DIN...pick one.   No brainer, use the Din.  

##  I use  7-16 Dins on RG-393.  Dins will handle  a lot of peak V.  UHF connectors like
PL-259 etc, are used in the shack only, and interconnections, etc.  Once it heads off outside,its 
dins only.  BNC is for 2m hand helds...and  type N is obsolete IMO.  Commercial world doesnt
use type N anymore.
