At the present time - my MFJ Antenna Analyser has it resonating at approx
10.5Mhz, and I am trying to get it to resonate at 1.8Mhz (160M).


What length and type of feedline are you using? If ladder-
line (or similar) your have a tuned-feeder system and the
resonance frequency may not be anywhere near the stand-
alone antenna resonant frequency.

What does the antenna analyzer say is the resonant
frequency closest to 1.8 MHz?

With the two above pieces of information, we can
estimate what needs to be adjusted to obtain a
system resonance of 1.8 MHz.
