true connector(s) losses?

I was wanting to dispel some myths about connector losses
Hi Myles,
They are largely myths. The true fact of the matter is in quality of
construction and selection of materials. However, even there with a
dedicated connection that is wrapped against the environment, a cheap
materials connector will work as well (still, it must have good
construction).
lose going from a DIN to an N via a adapter??
That's a new one on me. There are a lot of DIN standards.
some say the loss is actually neg some say it's going to add up and
the insertion loss could easily go over 1/2 db i dunno
Negatives add up to bigger negatives. The point of negatives is in
application. You can say a connector is specified at -0.1dB or that
it has 0.1dB loss - same thing. To say it has -0.1dB loss is
something of an anachronism, but it is often encountered.
exactly how good/bad is it?
Same dependencies I've already mentioned. You probably couldn't
measure it without sophisticated tools.
and where can u get some good low loss adapters (i know of ampenol) I
bought some unknowns at a flea market and they had great loss to which
in that case i attribute to just poor quality
I would then have to ask: How do you know they had "great loss?" 1dB
loss at the connection point would be as hot as a Christmas tree
lightbulb for 100W passing through it.
