(A)Contact-Initial Compression Stress Wave. When the piston (1) strikes the top of the tool (2), it sends a compressive stress wave (3) down to the.

Finally, it is important to remember that radials and counterpoise are two different things. - Radials are not a counterpoise-they are a capacitive coupling between the antenna and the Earth. The counterpoise to the antenna is the Earth itself. - A resonant counterpoise provides the necessary balance to a 1/4-wavelength vertical radiator without the need for a physical ground connection.
