Here's my cut and paste from my reply on the other forum where you asked this.

N connectors do not conduct RF better but they are a much better connector. PL-259's are good up to the VHF region but they are NOT a constant impedance connector. This means that the impedance of them does not stay constant with changes in frequency and by changes I mean over several bands. They can introduce an impedance bump in an otherwise perfect 50 ohm system. The N connectors are indeed a constant impedance connector and well suited for RF up into the gigahertz range where PL-259 fall on their face. Type N connectors are also weather resistant, not weather proof, but resistant and have a rubber O-ring seal inside. They are a bit of a pain to assemble but well worth it if running UHF frequencies. They now have some type N connectors that install basically just like a PL-259 making it much easier but I have not used any of them yet. I still install the old harder to deal with type. BTW all professional or commercial communications equipment except maybe some mobile radios on VHF and above frequencies do have type N connectors on them.
