Wes, prior to my change of QTH from Massachusetts to New Hampshire I was
one of those guys using a center fed doublet with tuned 600 ohm feeders and 40:1 VSWRs. I don't have any problem with non resonant antennas and/or high VSWR! Just manage the losses at a level you are comfortable with. I also posted that I would not be concerned with a 40 +/- j35 load [VSWR = 2.1:1]. If it causes the original poster problems then I stated 'trim' the antenna. Or, add/subtract feedline to eliminate the reactive component. Or, use a transmission line stub to both eliminate the reactive component and achieve a 1:1 VSWR. There are lots of methods to get to 1:1, but I believe it is not necessary. DD, W1MCE + + + Wes Stewart wrote: But in principle I agree the best place to do the matching is at the antenna. But when I say this, all of the guys using ladder line with 50:1 SWRs get all upset. |
