OCF: Proprer type of balun (transformer)
Richard Clark wrote in
: .... Thus, we would have a tripole antenna with three off-centers. Richard, are you sure you didn't serve an apprenticeship in the marketing department? So could you calculate the advantage as 20log(tripole/dipole), or is it just 10log(tripole/dipole)? Maybe the FCC's bodgy 40*log? The common mode path to dirt helps to tame VSWR excursions, between that and a lossy voltage balun at the feedpoint, you might keep VSWR under 1.5. And a bodged interpretation of Mismatch Loss could let the seller claim, VSWR1.5, no expensive lossy tuner, MismatchLoss0.2dB. Owen |
