Whip antenna calculator

The whip antenna is a flexible vertical rod antenna with a length of 1/4 or 1/2 wavelength. The antenna of the vehicle is generally 4 meters or 6 meters, and the backpack type is 2.4 meters.
These antennas are widely used in mobile applications and handheld walkie-talkies, and are the most commonly used antennas for short-wave, ultra-short-wave radios for mobile communications.
The calculator can calculate its performance based on the parameters of the antenna.
