Tom I don't have an answer for you.

I came across your message because I tried to use the MFJ Antenna Analyzer
to tune a 20 meter quad, and could not figure out how to get the "grid dip"
function to work.

So I will follow your thread with interest.

I recall reading about this many years ago but can't find it in any of the
books I have now.

How do I couple the meter to the antenna?

The project is a 3-element 2 meter yagi and I'm trying to set the length of
the driven element. I can't find a dip within the band using the rig and an
swr bridge.

Tom, N3IJ

Terry, If you use the MFJ 259B version you can go to Advanced Mode by
depressing 'Gate' and 'Mode' simultaneously. Press the 'Mode' switch to
cycle through the options. Select 'Resonance' Mode. You now can sweep
across your system, starting at the lowest frequency range [1.8 MHz] and
determine resonance at the Zero reactance frequency. Be advised, that
the load may not be 50 ohms though!!
