My DirecTV HD receiver uses (i.f.) frequencies up to 2150 MHz. Some
stacked TV distribution systems (multiple-dwelling units) go up to 3
GHz. Of course, these don't use BNCs.

Forgive my ignorance, but what applications above 1 Ghz use 75 ohm
impedances? CATV is the only major 75 ohm application I can think
of, and that's 1 Ghz and below.
Thanks and 73

Note another very important part of their statement -- that the 50
or 75 ohm impedance of the connector matters ONLY above 1 GHz, and
only then in demanding applications. At HF, VHF, and below, the
ONLY things that matters are that it fits the cable, it mates with
other connectors, is reasonably easy to install, and is
mechanically reliable.
