Furthermore the BNC was designed from the outset as an wide bandwidth,
low reflection RF connector, the RCA was most certainly not. It's one
of those "you can get away with it - just" situations. Why do you
think broadcast kit is all BNC for video ?

Generally connectors in broadcasting *have* to be more robust - as they
have to survive being plugged and unplugged many times. In other words
the same monitor or whatever might be semi permanently installed - or
used in a different place each day. And you need to keep the varieties
in use to a minimum. This simply doesn't - usually - apply to domestic
gear. I'm not much of a lover of BNCs. Having two types - 50 and 75 ohm
- which aren't immediately distinguishable isn't ideal. Nor are they a
particularly easy one to plug and unplug under arduous conditions. Not
that I can suggest a better one. ;-)

I used to use SMA connectors for a lot of lab systems, often having to use
a torque spanner to ensure reliable connections. Maybe we should all be
using SMA and semi-rigid coax for line level connections. 8-]
