The antenna is not 100% efficient so some of the TX power is reflected back to the radio effectively cancelling some of the power of the transmission. The closer to 1:1 SWR you can match the ant on a given freq. the more of the output power will actually make it out of the antenna.bimmerboodle Wrote:white_2kgt Wrote:I do as well, I had mine tuned years ago for the lower channels.breaker , breaker good buddy....why did you tune SWR for lower channels...like 9?
Well, when I got it tuned the guy said he could set it up so one side could have more power than the other, for instance, 1-20 might put out 6 watts and 21-40 would do the same, or I could set it up so 1-20 would put out 8 watts and 21-40 would do 4. Instead of having 40 channels that put out the same power I had him set it up so the lower channels would put out more than the upper ones. Make sense?
I have a modified radio
