For what ever it might be worth, I use 7/16 DIN connectors instead of either UHF or type N connectors.  Once I have connected a jumper to the back of a rig, I then use only 7/16 DINs all the way to my SteppIr.  My DB36 also uses a 7/16 DIN as I use a custom balun from Array Solutions.  I had Jay make my balun with a female 7/16 DIN, just as I had him build my PMII couplers with male and female 7/16 DINs.

A xxxx and his money are easily separated. In many respects, UHF
connectors are superior to Type N -- certainly with respect to power
handling, and the well known Type N issue with "creep" as the cable
stretches.

7/16-in connectors are certainly a fine connector, but they are not
cheap, and the UHF-series is entirely satisfactory for use below 100 MHz
in PRACTICAL systems. (caps added for emphasis).

Hi Alan,
What is a good source of the 7/16 DIN connectors in the US?

Thanks, Tom  KG7CFC

I found DIN 7/16 connectors at $80 per box of 25 on EBay a couple of years back.  Worth checking EBay regularly for these and other connectors.  
I mostly use UHF - Amphenol silver plated types only.  Max frequency in use here is 54MHz so no need to go to Ns etc.
YMMV
