According to:http://ham.srsab.se/ww/temp/test_MFJ269.pdf ARRL lab measures the range of the MFJ 269 is 6 to 400 ohms. Not sure what the difference is between this and the MFJ 259. Frank The anti resonant points are well within the MFJ 259 specifications stated above. The results you are measuring are certainly within the range of the MFJ 259. *As an example: a 493 ft dipole, 50 ft above an average ground shows anti-resonance, at 1.9 MHz, and is 15,000 ohms. Frank Frank, that is twice that you have mentioned dipoleas a comparison. May I remind you again that for equilibrium purposes the radiator must be a wavelength or multiple there of, assuming ofcourse we are considering a single radiator To talk of a "dipole" when considering my design is totally unreasonable.
