7 paź 2024 · The length of a quarter wave antenna for FM applications is 76 cm. Also known as Whip antennas, they are used in consumer FM radios such as the one shown in the picture below. At 100 MHz, the length is 75 cm.
2.1. Antenna length based on the following formulars: 1/2 λ dipole (feet)= 468 / frequency in Mhz. 1/2 λ dipole (meters) = 142.65 / frequency in Mhz. Full wave loop (feet) = 1005 / frequency in Mhz. Full wave loop (meters) = 306.32 / frequency in Mhz. Cut wire slightly longer for connecting insulators and pruning. 22-Jun-2007 09:30 AM.

30 lip 2024 · Our dipole calculator is a simple tool that allows you to compute the length of a simple antenna — it'll also provide you with the value of the wavelength and the adjustment factor [k].
30 lip 2022 · The formula for the length of a dipole antenna (calculate the length from frequency and wavelength); The dependency of the antenna length on the diameter of the conductor; and How to use our dipole calculator.
This calculator can be used to design a Quarter Wave Ground Plane antenna, with radials. The radiating element is a quarter wave (λ/4) and the radials are 12% longer. There are usually four radials, three being a minimum, but you could use up to six.
