The F-type connectors are used for making connections in systems based on 75 ohm impedance coaxial cables. They are available in screw-on, cone crimped and compression versions. They are mainly used in terrestrial, satellite, and cable TV systems, as well as in CCTV systems. The reliability of the connection, attenuation level, and impedance matching in the signal path depend on the design and quality of the connectors. Top quality MASTER crimped connectors guarantee long-term and failure-free o...

However, it happens that installers, misinterpreting their functionality, try to use them to measure the attenuation of an optical link (the so-called transmission method)....

The Signal GDW-505 A6777 repeater is used to amplify EGSM, GSM, DCS, WCDMA, and LTE signals and bring them indoors. The device is ideal for places where the signal is so weak that making calls or transmitting data via cellular phone is impossible. An example may be a place located far from the transmitter or a building with thick walls, cellars (coffee shops) or modern windows with panes of covered with metallic compounds....
