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??
