"UHF" connectors are very unfortunately named. They shouldn't be used for anything above 30 MHz (HF), but are often used on VHF (~150MHz) radios even though they have poor performance already at those frequencies:

> The stunning result is all the UHF connectors in the test have worse performance than all the other connectors. One immediate conclusion concerning ‘UHF’ connectors is they will function at these higher frequencies, but one must decide if using the PL259 or SO239 is worth it in an age where its deficiencies have been made moot by ALL connector designs since WWII.
N connectors work excellent all the way up to ~1GHz and also have decent power ratings. Above that SMA/SMC is popular for low power applications, and waveguides for high power.
TNC connectors were popular in the 1980's for analog cell phones and 800MHz public safety radios.
