F connector for coaxial cable 6.6mm (standard Cable)
Connector F Threaded for coaxial cable (T100 or similar) with Televes ring.
Connector F threaded 6.8mm for cable T100 or similar. Televes recommends it for all its wires in diameter between 6.8mm and 7.0mm. They are used for installation elements that use F-connector, such as antennas, shunts and distributors, mast amplifiers, and even the connector used by satellite receivers.
This is the most common F connector, the most used in any TV installation.
The O-ring is a circular rubber that goes inside the connector and makes it tightly attached and insulated. There are also F connectors without O-ring, but these with gasket are more advisable.
