Here it is:......a ROG or radial on ground (attached only to the tower
ground) gains some length due to the VF laying on earth.....this allows for
shorter radials that appear to be at RF longer. This would help top banders
with limited space.. It may not help in RFI situations but it sure beats
driving a metal stake or nail and the possible effects of a poor connection
and corrosion over time. I use huge spikes but only to secure the #12 or #10
solid electrical wire at the far end wrapping it around the spike but making
the copper exposed end pointing skyward out of the ground after I pound the
spike down.Maybe I am doing it wrong...please let me know.

OK so here is my question about wires on the ground and their velocity
factor as this isn't the first time I've seen reference to 50% or so
velocity factor for such wires. If this is true for radials, than is it
true for a beverage on the ground (BOG)? If so then is a 350' BOG the same
as a 700' beverage three feet off the ground?
