Enter the frequency, diameter, and number of turns into the calculator to determine the gain of your helical antenna.
Helical Antenna Gain Calculation Formula
The following formula is used to calculate the gain of a helical antenna.
Gain (dB) = 10 * log10((π * Diameter * Turns * Frequency) / c)
Variables:
- Gain is the directional gain of the antenna (dB)
- Diameter is the diameter of the helical antenna (cm)
- Turns is the number of turns in the helix
- Frequency is the frequency of operation (MHz)
- c is the speed of light (299.792458 MHz*cm)
To calculate the gain, multiply π, diameter, turns, and frequency, then divide by the speed of light and take the logarithm of the result.
