I 've read a lot of articles over the years about ground systems and how

ground vs frequency
N0AX's ARRL book on the topic is excellent. Also, these two links may
help. The first addresses grounding and bonding, the second about
radial/countepoise systems for verticals.

Some important points. The ONLY reasons for an earth connection are 1)
lightning safety, and 2) to make certain RX antennas work (Beverages and
some loops. An earth connection has NOTHING to do with noise reduction,
and it does NOT make TX antennas work better. That's the function of
radials/counterpoise.
