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.
