Gents,

If I bore the group with my "new-to-LF-so-not done-the-research " questions
then please tell me.

If not then:

Of the earth return loss resistance, how much of the resistance is the
actual earth rod(s)-to-soil contact and how much is the earth path ?

With an  inverted L antenna ,  is not a counterpoise of the same length as
the horizontal section and directly underneath but a few feet off the ground
a good way of avoiding the earth rod to soil contact losses ??

It is said that,  at HF, a few radials four feet off the ground are better
by far than an earth rod for a L/4 vertical "ground plane" . Does LF need
far more than four feet??
