When I put the meter between the 6011 and the LOW input of the duplexer, it is crazy high swr. With the meter between the ANT output of the duplexer and the antenna, swr isn't bad, but power drops to about 8 watts.

SWR can also have a detrimental impact upon the performance of microwave-based medical applications. In microwave electrosurgery an antenna that is placed directly into tissue may not always have an optimal match with the feedline resulting in an SWR. The presence of SWR can affect monitoring … Vedeți mai multe 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. … Vedeți mai multe The voltage component of a standing wave in a uniform transmission line consists of the forward wave (with complex amplitude $${\displaystyle V_{f}}$$) … Vedeți mai multe The most common case for measuring and examining SWR is when installing and tuning transmitting antennas. When a transmitter is … Vedeți mai multe The term power standing wave ratio (PSWR) is sometimes referred to, and defined as, the square of the voltage standing wave ratio. The term is widely cited as … Vedeți mai multe SWR is used as a measure of impedance matching of a load to the characteristic impedance of a transmission line carrying radio frequency (RF) … Vedeți mai multe 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 … Vedeți mai multe Many different methods can be used to measure standing wave ratio.

Web6 nov. 2024 · Pet (N6PET) found a high SWR on his Comet SBB 15 6M triband mobile antenna. By mounting the antenna on a 2M quarter wave counterpoise made from 2 speaker wires, he was able to drop his SWR below 1:3:1 for the frequency range of 50-54 MHz. Web10 ian. 2015 · So all is not lost simply because the SWR is high. A final point about SWR: it does not indicate resonance of the aerial. It indicates a good match between the feeder and the driven element. It does not mean it will radiate well either – remember that a decent dummy load will have a good SWR and that doesn’t radiate at all well.
