I completely agree.  I do not use PL-259 at work except for some 
Marine radio equipment.  Motorola mobile has gone to the mini-UHF and 
cellular is mostly TNC.  Base stations and repeaters are all 
N-connectors as are the duplexers.  All my antennas have N connectors 
as do the hardline runs.

What I hear from local hams is "its too hard to assemble N 
connectors" to which I say "hogwash" (a US term meaning 
ridiculous).  N connectors only require soldering the center pin 
which normally is gold plated.   PL-259s require "tons of heat" to 
solder the shield which risks melting the center insulator of the 
coax.  I have more instances of shorted PL-259 connectors.

MY DEMI xvtrs all are equipped with N-female and BNC connectors for 
RF connections.  It seems that mostly ham radios made in Japan come 
with SO-239 (female) connectors...and I would say this is because US 
hams are requesting them on their equipment (or have in the past).

My FT-847 has one N connector for 70cm but the other bands are all 
SO-239.  I added two sma connectors for separate Rx antennas on 2m 
and 70cm.  All my mw gear use either N, TNC, or sma's.......so???
