Web31 dec. 2009 · 170. Dec 31, 2009 #1. hello, i have my ms-250 all wired up from the battery. when i hook it up to my 949, my swr readings go up to 1.4 - 1.5. if i move the amp, it shoots up to 2.5 - 3. when the power is tured on, the swrs drop slightly to 1.4. when i take the amp out of line, my swr drops down to 1.2 - 1.3. could the patch cable i use to run ... Web(The SWR on the coax/antenna side of the tuner does not change with a tuner in the shack.) The RCS-6 has shorting switches / higher isolation, no control signal on the coax, and 6 ports. But it does require a seperate cable for control. With several wire antennas in 100' tall trees I like having just one coax cable into the shack with the RCS-4.

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.
