A few years ago, I took down my old Cushcraft A3 and gave it a good going
over. It had been tapped by lightning (I've got the old element segment
with the burned hole in it) and needed fixing.
I replaced the old trap covers, cleaned the traps of invertebrate chitin and
nests, verified the trap resonant frequencies (two traps were bad --
cleaning the trap connections fixed everything), etc. (No. I did not polish
the elments -- that's for type A personalities)
For verifying trap resonant frequencies, I used a B&W grid dip meter and
getting great dips with the traps.
When I had started dismantling the antenna, I ordered the MFJ dip coil for
my 259 to see how it would do--as an antenna analyzer, it's the best. So, I
hoped it would be good as a dip meter, too.
When it arrived a couple of days later, I tried it out on the traps. Not so
much as a wobble of the meter. With the B&W coil/dip meter in the same
position, I got a big dip! I tried various places in/around the trap and got
nothing with the MFJ coil/analyzer.
It may well work in other areas where a dip meter is needed, but in this
particular case, it didn't work at all.
