Phil, It is great that you actually know the length of your feedline - most do not.
I am not questioning how well your antenna/feedline combination works. All I am trying to get across is that for any claims about how easy a particular antenna is to tune (with a tuner in the shack), the length of feedline is a critical parameter. Yes, I know that most hams do not measure their feedline - it is long enough to reach from the shack to the antenna. That means the experience you have with that antenna/feedline combination may not be the same as the results obtained by anyone else. Bottom line, measure your feedline, particularly if the antenna is not matched to the feedline characteristic impedance. 73, Don W3FPR On 9/30/2012 12:46 AM, Phil Hystad wrote: > Don, > > Actually, my antenna works quite well and so far is the best performing wire > antenna I have raised > up for 80/40/30.
