Whip Antenna Calculator

A whip antenna is the most common example of an antenna, a single driven element and ground plane antenna.

Whip antennas are mounted on hard and flexible wires, usually vertically with one end close to the ground plane. A whip antenna may also be called a half-dipole antenna.

These antennas are widely used in mobile applications and handheld radios. They are usually attached to the vehicle and are designed to be flexible so they don't break out of time.

The formula for capacitance is a percentage function of wavelength.

Matching the choice of inductor, the antenna resonates at the desired frequency.

When the antenna is fully adjusted, then it looks like a pure resistor tied to ground. This resistance is called radiation resistance.
