I might add that the Kindle version of N0AX's book is available on
Amazon for only $9.99. The Kindle version is pretty cool because you
can click on hyperlinks and look at them easily. If you don't have a
Kindle, you can use Amazon's free app to read it on a computer.
Actually, for a book like this, with illustrations and hyperlinks, that
is my preferred way to read it.

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.
