I have recently acquired an antenna analyzer and have been getting my mobile
antenna ready for the summer (if we have one!). My procedure has been to
attach the analyzer to the base of the antenna or via 1/2 wavelength of coax
and tune the antenna to read j0 on complex impedance. This should then be
correctly resonant. I then look at the real (resistive) part of the
impedanceand use a transformer to match it. For example on 20M the antenna
reads 35 + j0 so I have a transformer toroidal transformer from 50 ohms to
35 ohms. This seems to work well.
Question is whether tuning for j0 is going to give a true resonance of the
antenna? Any other suggestions?
