Thanks, guys - I wasn't aware of a torque standard - guess I've been
spoiled by BNCs.

Hi Pete,
Good SMA connectors are very reliable. They are used extensively in
microwave test equipment as well as military and spaceflight hardware.
The torque spec is typically between 5 to 8 in-lbs. If you don't have
a calibrated torque wrench you can snug them up with a 5/16 open-end
wrench. Finger tight is okay for a quick and dirty measurement, but
for anything where you want stability over time they need to be
tightened with a wrench. This is especially true if the cable in
question gets twisted or moved in such a way that it can transmit
torque into the connector. That will loosen a hand tight connector and
sometimes even a torqued connector.

I'm not sure if this is the right place or not, but thought I'd ask
because this is at least a feedline question.
I have a number of SMA connectors in areas of my station like my RBN
SDR and my N1MM Spectrum Display. It seems like every few weeks I
start running into problems, and have to go through and retighten
them to get rid of intermittent signal losses. Is there anything
that can be done to secure them better?
