1 4 Wave Mobile Antenna Calculator

This calculator will help you to calculate the different wavelength of antennas based on the frequency.

1 4 wave mobile antenna calculator.

This calculator is designed to give the vertical length height of a particular antenna for the frequency and wavelength chosen. Use our simple calculator to determine approximate dimensions of materials needed to build a vertical antenna. This calculator on the whip antenna mentions formula or equations used for calculations. 7 15 for the 40 meter band.

A horizontal 1 2 wave length dipoles will have a feed point of about 73 ohms while the inverted vee antennas have a feed point of about 52 ohm s. This calculator can be used to design a quarter wave ground plane antenna with radials. I have been making a few 1 4 wave antennas lately mainly for uhf and the ghz bands with good success so i decided to create a calculator to simplify the process and maybe get some people who have not tried one before to give it a go. 1 4 wave antenna calculator.

This calculator is designed to give the vertical length height of a particular whip type antenna or the frequency of it. Both can be used with or without a 1 1 balum although the use of a 1 1 balum will change the feed point of the unbalanced coax to a balanced antenna load there by reducing the chance of radiation from. Whip antenna calculator monopole antenna calculator. It is inversely proportional to the frequency which means the wave with higher frequency will have shorter wavelength.

This whip antenna calculator calculates various parameters of whip antenna or monopole antenna. One might have seen long straight rod on the car it is known as whip antenna. It consists of flexible wire. I guess you could see it as the spike on a x mass tree.

The radiating element is a quarter wave λ 4 and the radials are 12 longer. Choose from quarter wave half wave the powerful 5 8 wave 3 4 wave or full wave and calculate minimum lengths of required radials and then shop for your needs on our other pages and select from our inventory of aluminum fiberglass wire coax connectors and other parts and. Ahh the good old quarter wave ground plane. The antenna calculator for half wave dipoles.

Of nearly all antenna designs the 1 4 wave requires the most space making it difficult to place with other antennas on a mast. This does not take into consideration the type or size of horizontal reflectors of even if there is a need for them. Enter one only one value the desired frequency or the antenna length in any length field. There are usually four radials three being a minimum but you could use up to six.

Frequency calculations are based on radio waves traveling at the speed of light 299 792 458 meters per second.
