WebThat’s where the antenna tuner comes to the rescue. By using different amounts of inductance and capacitance, the antenna tuner can convert the antenna system impedance to 50 ohms for the radio. The result is a 1:1 SWR, and your transceiver is happy to dump its power into the circuit.

Yes, but the mismatch isn’t nearly as important for receivers as it is for transmitters. For example, a 6:1 VSWR sounds terrible, but on reception you’d only lose 3 dB signal strength with that bad a VSWR. Note that you’d also lose 3 dB of the backgrou...
In radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide. Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the … See more SWR is used as a measure of impedance matching of a load to the characteristic impedance of a transmission line carrying radio frequency (RF) signals. This especially applies to transmission lines connecting See more Using complex notation for the voltage amplitudes, for a signal at frequency $${\displaystyle \nu ,}$$ the actual (real) voltages Vactual as a function of time t are understood to … See more Many different methods can be used to measure standing wave ratio.
