The distance between one point to another adjacent point in a wave is known as the wavelength. It is inversely proportional to the frequency which means the wave with higher frequency will have shorter wavelength. This calculator will help you to calculate the different wavelength of antennas based on the frequency.

Formula:


Wavelength (WL) = Wave Speed / Frequency
Where, Full Wave = 984 Half Wave = 492 Quarter Wave = 246

Antenna WaveLength

FullWave

Let us consider the frequency as 2400 mHz

Solution :
WL = 984 / 2400  = 0.41 feet
WL = 0.41 * 12  = 4.92 Inches
WL = 0.41 * 0.3048  = 0.1249 Meter

HalfWave

Solution :
WL = 492 / 2400   = 0.205 feet
WL = 0.205 * 12   = 2.46 Inches
WL = 0.205 * 0.3048   = 0.0625 Meter

Quarter Wave

Solution :
WL = 492 / 2400  = 0.1025 feet
WL = 0.1025 * 12  = 1.23 Inches
WL = 0.1025 * 0.3048  = 0.0312 Meter

Note

1 Feet = 12 Inch
1 Feet = 0.3048 Meter

This tool will help you dynamically to calculate antenna wave length.
