Enter the operating frequency to calculate the side length of a delta loop antenna. The calculator will provide the length in meters for each side of the equilateral triangle that forms the delta loop.

Delta Loop Antenna Formula

The following formula is used to calculate the side length of a delta loop antenna.

L = frac{300}{f sqrt{3}}

Variables:

  • L is the side length of the delta loop antenna (meters)
  • f is the operating frequency (MHz)

To calculate the side length of a delta loop antenna, divide 300 by the product of the operating frequency and the square root of 3. This calculation assumes that the speed of light is approximately 300 million meters per second.

What is a Delta Loop Antenna?

A delta loop antenna is a type of radio antenna with a loop shaped like an equilateral triangle. It is known for its high efficiency and directional characteristics. The antenna operates on a resonant frequency, and its size is determined by the wavelength of the radio waves it is designed to receive or transmit. The delta loop antenna can be used in various applications, including amateur radio and broadcasting.

How to Calculate Delta Loop Antenna Side Length?

The following steps outline how to calculate the side length of a Delta Loop Antenna.


  1. First, determine the operating frequency (f) in MHz.
  2. Next, use the formula L = 300 / (f * sqrt(3)) to calculate the side length (L) in meters.
  3. Finally, use the calculator above to verify your result by entering the frequency and observing the calculated side length.
