I use DIN 7/16 on Cellflex cables and RG-217, RG-218 as well as DIN 13/30
with RG218 since the eighties on all cabling outside the shack.
The equipment I was working with in the Airforce until 1975 was type C, DIN
7/16, 4,1/9,5 or Dezifix by R&S.
Type N showed up later in Germany on commercial equipment.
The latest in use on mobile network sites is DIN 4,3/10.

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 BNC is for 2m hand helds...and type N is obsolete IMO.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.
