As far as I know you'll need V5 connectors. I know I've got some V5 DIN 
females, but I'll check for N's next time I go to the shop. Andrew never 
made UHF connectors for the VXL5, in fact they no longer make UHF 
connectors for any Heliax. If you used DINs you could make DIN-M to N 
jumpers or DIN-M to UHF jumpers for the terminations.
