The F Connector is commonly used for “over the air” terrestrial television, cable television, and universally for satellite television and cable modems.  It is inexpensive and yet has a good 75Ω impedance match up to 1 GHz with a usable bandwidth of up to several GHz.  These connectors are typically crimped, however the cable industry standard now is to use compression fittings.  Female connectors have a 3/8-32 thread with most male connectors having a matching threaded connecting ring, though push-on versions are also available.  However, push-on connectors provide poor shielding against airborne signals. The threaded version of the BNC Connector is the TNC (Threaded Neill-Concelman) connector.  They have a 50Ω impedance and operate best in the 0-11 GHz frequency spectrum.  The TNC connector offers better performance than the BNC connector at microwave frequencies and is employed in a wide range of radio and wired applications.  There are 75Ω versions also available, providing a good SWR (Standing Wave Ratio) to about 1 GHz, which can be recognized by a reduced amount of dielectric in the mating ends. UHF (Ultra High Frequency) connectors are generally usable through VHF and HF frequencies and can handle RF power levels over one kilowatt.  Despite the name, it is rarely used for actual UHF frequencies as they do not work well above 300 MHz.  They are widely used in amateur radio, citizens’ band radio, and marine VHF radio.
