A 75m Texas Bugcatcher loading coil certainly
qualifies as a distributed load being about
1/8WL long.

A 75m Texas Bugcatcher loading coil is about 30 feet long?

*Electrically*, yes. Its velocity factor calculates
out to be about 0.02 at 4 MHz and it is physically
0.563 feet long. 0.563'/0.02 = ~28 feet.

At 4 MHz, a 75m Texas Bugcatcher coil replaces ~28 feet
of wire in the antenna. That is ~41 degrees at 4 MHz.
(Note there is about 44 feet of wire in a 75m Texas
Bugcatcher loading coil.)

Equation 32 in the following IEEE paper is what I used
to calculate the velocity factor of the loading coil.
