Say you have an half-wave, end fed antenna that is layed out as an

inverted
L, 26 feet vertical, 40 feet horizontal. Can you convert this 40 metre

EFHWA
into a J pole by running the J part near the ground?

ie

My guess is that the input impedance of this antena is on the order of a few
hundred ohms as compared to the input impedance of a normal J poles
"radiating section" which would be a few thousand. A balun may be the better
way to go.
