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.
