Hello,
Can someone please explain me how the coaxial cables work?
I'm looking for low loss BNC and SMA cables - 50 Ohm. Low loss is a
requirement, and as long as the  price is not $1/ft for 500ft, any
reasonable price is ok. Most of my applications are <200MHz.

I see here http://www.gme.net.au/land/antennas/coax_cables.php
that RG58AU is a low loss BNC
from the data here http://www.ssbusa.com/comaircom.html
RG 213 seems to have even lower loss value


Now, on that last website ECOFLEX has even lower db loss. Ecoflex 10
can work with BNC, does it mean I can use it as conventional BNC cable,
just with low loss?

I read the BNC connectors are for average speed and SMA connectors are
for high-speed. Is it true? And can I place BNC, SMA and SMB connectors
on the cable from the same spool?

Thanks,
Vitaliy
