The inference here is that UHF connectors are somehow outmoded. Nothing
could be further from the truth. The FACT is that they are entirely
satisfactory for systems operating below about 500 MHz, and
mechanically, they have some significant advantages over most other coax
connectors when installed on most coaxial cables .
Those other newer connectors DO have advantages above 500 MHz, where
their constant impedance characteristic matters, and where their small
physical size takes up less space.
Why is so much new equipment coming with N connectors, or with other
smaller connectors? Mostly because that equipment operates at those
higher frequencies, where their advantages DO matter.
Methinks that the poster of this comment needs to go back to study the
fundamentals of transmission lines. The ARRL Handbook and ARRL Antenna
Book are a good place to start.
