WebThe tuner may provide the 50 ohm match to your radio, but the mismatch and high SWR still exists between the antenna tuner and the antenna! This translates to high losses in the coaxial cable. On the other hand, using an antenna tuner with ladder line is a good way to go – at least for HF work. WebIt means that if you apply 1 V RMS sine wave of that frequency at the end of the antenna, a 1/50 A RMS current will flow in the antenna at that point. V = IR. Exactly. This can be generalized to the statement that the ratio of RMS voltage to current at any point on the antenna is 50, and the unit is, of course, ohms.
