Smallest denominator

You can run hundred n connectors and you will still need a 259 to connect to radio

Not only are they not waterproof, they are 37 ohm vs 50 ohm for the N connector (why put a 32 ohm connector - really a number of them into a 50 ohm coax run that we have worked so hard to ensure stays 50 ohms).  Much of what I am trying to get at here is for the new Ham (you know the Techs and new Generals - come on Tony Moore pass that Gen test on Sat,!!!) why shouldn't they start out using N connectors??  They have to invest in something and many will tell you the N connector is a better initial investment.  What I am hoping to do here is run a dialog on what is best vs what I/we have always done.  I used to have a sign on my desk in the Navy that answered for Junior Officers and even worse Junior Officers with their Chief Petty Officers in tow that said "Just because we have always done something a certain way, doesn't mean we haven't been doing it wrong all along - BE FLEXIBLE, LEARN!!".  I am just trying to learn - to be flexible - I am still so new that I have junior enlisted vs Commander Department Head level knowledge.
