how much SF6-Air Analyser for cables

The most common case for measuring and examining SWR is when installing and tuning transmitting antennas.When a transmitter is connected to an antenna by a feed line, the driving point impedance of the antenna must match the characteristic impedance of the feed line in order for the transmitter to see the impedance it was designed for (the impedance of the feed line, usually 50 or 75 ohms).
