Jim,

I looked at dins a while back, considered trying them but they were very expensive. Maybe things have changed, can you recommend a supplier, and what kind of price for LMR600 dins ?

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  BNC is for 2m hand helds...and  type N is obsolete IMO.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