Yagi Antenna Gain Calculator

Based on rothammel dl6wu you may want to combine it with a folded.

Yagi antenna gain calculator. Antenna gain calculator example. There are several features of the design of a yagi antenna that affect its gain. The calculators for other antenna types such as parabolic horn dipole and patch are also mentioned. Another ham brought to my attention that i should have indicated if this yagi antenna calculator is built with the yagi beam elements isolated from the boom or not isolated.

Yagi uda antennas consist of a single driven element connected to the transmitter or receiver with a transmission line and additional parasitic elements which are not connected to the transmitter or receiver. Antenna gain calculator equation. Free online engineering calculator to find the dimensions of a yagi uda antenna for a given frequency range and length. Yagi uda antenna calculator you may want to combine it with a folded dipole.

This page covers 3 element yagi antenna calculator. For people who can get them high enough and have a method for rotating them yagi uda antennas are among the best choices for dx work. A yagi uda antenna commonly known as a yagi antenna is a directional antenna consisting of multiple parallel elements in a line usually half wave dipoles made of metal rods. What is yagi antenna.

Number of elements in the yagi. The dl6wu yagi is highly regarded as being easy to build with repeatable results broad bandwidth and a useful pattern. If the parasitics differ much from 0 4 0 05 λ or the gain is larger than 16 dbd you should get distrustful. Yagi uda antenna gain considerations.

To design the antenna you need to go to task design yagi menu. The simple yagi antenna is shown in the figure 1. Long yagis are commonly used from the 144mhz amateur band to the 2 4ghz band. Their directional selectivity and high gain mean quieter received signals and stronger transmitted signals than many other antenna options.

The most obvious factor that affects the yagi antenna gain is the number of elements in the antenna. With this yagi antenna calculator you will be able to build your own yagi antenna or at the very least compare it to other commercially made yagi antennas. Typically a reflector is the first element added in any yagi design as this gives the most. Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47.

It is very useful in rf system link budget calculation and analysis. However if the parasitics differ much from 0 4 0 05 λ or the gain is larger than 16 dbd you should get distrustful. Free online engineering calculator to find the dimensions of a yagi uda antenna for a given frequency range and length. Yagi calculator is a windows program that also runs well on linux ubuntu 8 10 under wine to produce dimensions for a dl6wu style long yagi antenna.

Using this software you can design and build your own yagi antenna this software can not only be used to design but also to find out antenna gain stacking distance and standing wave ratio swr. Yagi uda antenna calculator. The formula and basics of yagi antenna calculator are also explained with example.
