I tend to agree with Danny on this one.
I haven't broken an SMA connecter yet, but I've known of many instances
where this has happened. Far fewer instances of BNC connecters breaking off
the radio or snapping.
Also, BNC connecters are far more ruggedly constructed and due to their
larger size, are far easier for blind ops to repare than an SMA.
Also, a female BNC, IE the connecter on the radio itself, has far less
friction on it when taking antennas on or off...an SMA style set up requires
you to screw the antenna on or off the radio, and the center pin of the
antenna, or at any rate, the male part of the SMA connecter drills into the
female part of the plug until the connection is tight. This causes metal
fatigue. With a BNC connecter, you just press the two halves together, and
give a quarter turn and it's done.
far far less stress on the electrical connection point.
Perhaps the BNC might endure more strain or stress because it sticks out
further from the chassis of the radio, but this is compensated for by the
fact that the mounting is far more rugged compared to a female SMA
connecter.
commercial radios, and some of the newer commercial/ham radios from china
use a male SMA on the radio, and this reduces allot of the above mentioned
problems inherent with an SMA connecter.
If the antenna snaps off, you can easily replace the antenna instead of
having to send the radioin for repares.
Whereas the tradditional radio female connecter will snap off with the
antenna in most cases and requires costly repares.
All that said, personal experience is what you have and if your satisfied
with your own observations, then that is good.
but just try to remember this the next time someone posts to the list about
another sma snapping off the radio when it is dropped or impacted.
In 6 years of being on this particular hams list, I've never heard of that
happening to a BNC connecter on an HT.
