You load your antennas with a Tesla coil? Did you read the part
about a Tesla coil going to a lumped inductor when it was shortened?


A minimum Tesla coil is 1/4WL. My 75m bugcatcher coil
mounted on my pickup as a base-loaded coil with no
whip is 1/4WL on 6.6 MHz. Going from 6.6 Mhz to 4 MHz
is only 40% shortening. I think the lumped inductor
crossover point is probably pretty far below 4 MHz.

Why don't you crunch the numbers using your reference and find out for
sure? (If your reference is correct, that is. Some of the papers by
academics on the web don't always give information that
corresponds to reality.) You should be able to analyze your
bugcatcher easily and report what you find. It sure beats
sitting around drinking Ripple and feeling persecuted.
