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
