F type connector connected into a televisionĪs virtually all cables use the male connector which is particularly low cost and relatively easy to assemble, this provides for a low cost and very effective connector solution. These do not require tight tolerances and this means costs can be controlled. In this way, the male F connector consists of only a body, which is generally crimped onto or screwed over the cable shielding braid, and a captive nut. The connectors are arranged so that the dielectrics of the two halves are in contact, thereby producing an almost constant impedance across the connectors. The male has a captive nut with a thread on the inside and the centre pin - typically this is the centre conductor of the coax itself. The female connector has a receptacle for the centre conductor and a barrel containing the spacing dielectric on the inside and on the outside is the thread. The thread for the F-type connector is a 3⁄8 in-32 unified extra fine (UNEF) thread. The connector has male and female connections, uses a threaded outer to provide reliable contacts and it provides good 75Ω match for signals extending well above 1 GHz. The F type connector is an inexpensive connector that provides the required performance for many domestic TV related applications. With its increased use it has been standardised by the International Electrotechnical Commission under its standard IEC 60169 which standardised radio frequency connectors. With the globalisation of TV equipment, and the wider adopting of satellite TV, the connector has come into more global use, first for satellite TV and then for terrestrial TV cables. It was cheap and performed well within domestic TV situations. The connector became widely adopted for VHF and then UHF television in the USA. The F connector was developed in the USA in the 1950s by Eric E Winston of Jerrold Electronics, a company that was developing equipment for the domestic TV cable market. These connectors were developed around 1922 and naturally their performance is not up to that of UHF TV. The F type connector provides some significant improvements over the Belling Lee connectors (IEC 61169 part 2) that are widely used in Europe. The connector is usually used with RG-6/U cable, although it can also be used with the older RG-59/U cable. In Europe, cables for down-converted satellite signals that fall between 950–2150 MHz from LNBs and DC power and block signalling from satellite receivers exclusively use F connectors. The F connector or F-type connector is a form of coax cable connector that is widely used with domestic television equipment.The F connector is cheap and can perform to frequencies in excess of 2 GHz making it ideal for terrestrial and satellite links between antennas / down-converters or LNBs and the television itself.
