Found this handy chart via Packet.  Sounds fairly close to the discussion
here.  Anyone care to clean up the specs and descriptions and add the
appropriate details for the recently discussed 7/16 DIN, please?  Properly
completed I'd guess that this chart may find it's way into the notebooks,
and on to the corkboards, of many TowerTalk Ham shacks!  It will in mine.

Connector type       Impedance    Description.
----------------------------------------------------------------------------
--------------------------------
Belling Lee            75         An economy connector used almost
exclusively
                                         for television equipment. Its main
advantage
                                         is the low cost.

BNC                     50         A bayonet fitting connector suitable for
use
                                       (75 ohm version   up to 10 Ghz. It
is widely used on
                                       available ) professional equipment,
although it is not
                                       particularly common on commercially
produced 
                                       amateur equipment.

Miniature BNC      50     A miniature version of the ordinary BNC
                                        connector.

N                         50     A screw fitting connector suitable for use
up
                                    to frq's. of 10Ghz. and sometimes
above. It
                                    is often used in situations where good
RF 
                                    performance is essential, and it is
often
                                    used in high power applications above
300
                                    Mhz.

SMA                    50     A high quality miniature screw fitting
                                    connector for use up to 18 Ghz. It is
found
                                    in many professional microwave
applications
                                    where miniature flexible or semi-rigid
cables
                                    are used.

SMB                    50     A high quality subminiature snap-on type
                                    connector suitable for use up to 18
Ghz. It
                                    is very convenient to use in similar
                                    applications to the SMA or SMC
connectors,
                                    but it is not as robust.

SMC                    50     A sub-miniature connector similar in many
                                    respects to the SMA connector. However,
it is
                                    smaller.

TNC                    50      A scew fitting connector very similar in
                                    size and characteristics to the BNC
                                    connector. 

UHF                    50      A non-constant impedance connector which is
 (PL259/SO239)             widely used on amateur equipment up to 146
                                    Mhz. At frequencies above 200Mhz. it
                                    introduces a hight VSWR.

7/16 DIN
