Re: simple question
An RF ground is usually wire that is parallel to the ground in a radial
pattern (wheel spokes) in 1/4 wave or more lengths.
An electrical ground is a deep metal conductor or conductors that would take
a direct lightning strike without vitrifying (glassing) the soil.
My easy made ground for Tesla use is 3, 20 foot lengths of 3/4 inch copper
pipe in the soil. Just buy the plumbing for a garden hose connection and
hydraulic action of the water will drill it in the soil.
