Dave,
I use the RFN-1002-1SI male-N connector with both LMR-400 and LMR-400UF. I have over 20 of them in use in my 2m-eme antenna array. They also fit Belden-9913 cable (but I do not recommend using 9913). No need for any center conductor trimming.
Ordinary N-Male connectors are sized for RG-8/RG-213 coax which has a smaller diameter center conductor. Using them will introduce a small impedance "bump" since one must trim LMR cables to fit them.
In 10+ quantities the RFParts connector costs $5.50/ea. Not that bad an increase over the standard N-Male (In fact about the same cost as Amphenol N-Male's).

Either the correct connectors from Times Microwave, or the RF Industries connectors for "9913" will work. Sounds like whoever you got the connectors from gave you the wrong ones, as I've installed hundreds of N connectors on this type of coax without ever having to trim some strands from the center conductor.
Times connectors: TC-400-NM crimp TC-400-NMC clamp type
RF Industries: RFN-1002-1SI clamp type RFN-1006-3I crimp type

As I recall, the last time I had to attach N connectors to LMR-400 Ultraflex coax, I had to cut off at least 2 strands of the cable's center conductor in order to make it fit into the N connector I was given. Can anyone recommend a preferred N connector plug that is designed to fit LMR-400 Ultraflex without having this problem?
