    One might want to consider local climate. Here in central PA where we are 
known to have weather changes, I used an 'N' type connector since it was 
generally accepted by the military. However, because of the aforementioned 
weather conditions, the 'receiving end of the connector expanded and created an 
intermittent connection. After that episode, I used nothing but SO-239/PL-259's.
My nickel's worth.

This depends on the mode and frequency.  SSB causes considerably less I^2 
x R heating in conductors than RTTY.  For years, when jammed, I ran 14 on 
40m with Type-N connectors, sans-grief.  By accident, I ran 6 to Type-BNC 
on 160m - again, 'no-problema'.  With a DC hi-pot, either Typs N or BNC 
break down at c. 4kV -- which @50-ohms is a whole bunch.
Type C  breaks down at over 5kV, and it has lower-R contacts than the 
above.  It is bayonet-mount for easy on/off.

Type-UHF needs drain holes cut in the coax jacket to let rain water out.  

For >15k out, Type-7/16 DIN is in.
