Let s Talk Transmission LinesDon t neglect one of the most important parts of your station!By Edward J. Farmer, AA6 ZMNo one wants to discuss Transmission Lines . Many hams would rather chew aluminum foil. After all, Transmission Lines are just the cables that link your radios to your antennas. You hook them up and get on the air. Who cares? Boring!Well, the subject may not have much sex appeal, but if you want to get maximum performance from your station, give me your attention for a couple of minutes. These Lines have a major influence on the results you ll achieve on the air.
In addition, the transmitter-end impedance of the line is no longer the 50 Ω the radio needs. The impedance presented by the transmission line now depends on the impedance of the antenna relative to the line’s characteristic impedance and the length of the line.
