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 ... Web9 sept. 2024 · The SWR from the 6011 going directly to the antenna is very good. Around 1.2 and about 44 watts. 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.

Web27 aug. 2024 · For the multi-band Hustler antennas, this unit can aid in matching the low-impedance feedpoint to a reasonable SWR in the user-selected portions of 80 or 40 meter bands without affecting the operation on the other, higher frequency bands. The DXE-VMN-1 has a special coil tap clip to make the inductance adjustment needed for the correct match.

The lower the SWR is, the higher the Return Loss. For example an SWR of 2:1 is equivalent to 9.5dB RL and an SWR of 1.1:1 is equivalent to 26dB RL. A perfect (but unachievable) 1:1 SWR is equivalent to a Return Loss of infinity. In the real world an SWR better than

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. the others 1972http://www.radiohamtech.com/SWR%20myths%20and%20mysteries.pdf the others 123 movies
