Coax cable / Antenne plug

The Coaxial cable was born in 1880 and is a type of electrical cable having an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conductive shield.

All coax cables also has an insulating outer sheath or jacket. A coaxial cable is a transmission line used to carry high frequency electrical signals with low loss. It is used for broadband network cabling, cable television signals and connects the radio transmitters / receivers for their antennas.

This is very important that a coaxial cable is made from high-quality materials, as 100% pure copper and that the tubular insulating material provides high isolation, and here is foam-isloator best.

it is important that a coaxial cable is as short as possible as it works signaldæmpene. A coaxial cable for radio transmitters is 50 ohms - the resistance is called impedance and should be appropriate for the radio transceiver - opposite the device (eg. An antenna) must be designed with the same resistance. Possibly. mismatch will provide reflections of the cable and destroy / interfere with signal transmission. Video Signal transmission should the impedance is 75 ohm (RG59)

A transmitter and receiver sees a coaxial cable which many complex passive components - capacity between conductor and shield, coils in series, and an ohmic resistance (loss in copper) .

a loss in a coaxial cable applies to both transmitter and receiver. A powerful coaxial cable for example. LLC400 (10mm thick) provides approximately 22dB loss per 100meters at 2.4GHz (WiFi). A LCC200 (5mm thick) gives a loss of some 100meters per 55dB at 2.4GHz. Remember to compensate Coax cable loss with passive Gain antenna if possible. Avoid any active 2-Wejs signal amplifiers.

Remember: Good quality cable offers the best connection.
