F
The F Series RF connectors from Telegärtner are designed for use up to 3 GHZ and as such are ideally suitable for HDTV applications. The F series connectors have a threaded coupling mechanism; the impedance is controlled at 75 Ohm. Cable terminations are either crimp or solder designs. The F series connectors are primarily used in the transmission of analogue and digital video signals. The F-Series connectors from Telegärtner have been specially optimised to meet the highly stringent Return Loss requirements up to 3 GHz demanded in professional and HDTV applications.
