The PL-259 was in use primarily for carrying VHF and UHF
signals, not baseband video.
The PL259/SO259 was originally designed in the 1940's to carry
the then high resolution 3.5MHz 405 line baseband video signal.
They remained as the connector of choice, at least in europe, until
the 70's when the more compact BNC took over. Patch pannels
were, and are still, mostly Musa as they are easy to (un)plug
even when packed closely.
As I said, I may be sorry to have chimed in on this nearly
off-topic conversation, but when I see blanket statements
being made that are obviously incorrect I have a hard time
remaining silent.
Ah, ok. 8^)=
