It could be that the antenna is designed in free space, and you had to mount the elements to a boom to make it. The boom adds negative reactance to the elements. This not a problem on hf, a minor problem on 2 meters, very noticeable on 440 mhz and can destroy a 1.2 ghz design. Download Yagi Designer 2.0 (.zip) Parabola Calculator 2.0 is a freeware program that was written to help you design solar collector or wifi projects using parabolic reflectors. This program calculates the focal length and (x, y) coordinates for a parabola of any diameter and depth. ANTENNA DESIGN FOR FREE USING MMANA-GAL SOFTWARE 1. AVAILABLE ANTENNA DESIGN SOFTWARE EZNEC and 4nec2 are based upon the Numerical Electromagnetics Code, or NEC, which is a popular antenna modelling system for wire and surface antennas originally written in FORTRAN in. Yagi Calculator is a free antenna design and analysis software for Windows. 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). To design the antenna, you need to go to Task Design Yagi menu. QY4 ANTENNA DESIGN PROGRAM DOWNLOAD. BY WA7RAI Introduction to the QY4 Yagi Design Program. This article below was written by WA7RAI and will serve to introduce you to a computer program for designing Yagi antennas that you can download.

LinearDipole - set length to 0.5(half-wavelength dipole) and notice that theimpedance is near 73 ohms. Radiation pattern shown is typicalfigure-8pattern. When a half-wave dipole is close to ground, the impedance isloweredto near 50 ohms. Thus a perfect match to 50 ohm cable.
-set lengthto 1.27 wavelength. This is called an Extended Double Zeppantenna and produces the maximum gain possible from a simple center-feddipole. Notice that the radiation resistance (impedance) is about 90ohms. This antenna can be matched to 50 ohms by using a seriesinductor.Half of this antenna is 5/8 wave and is a common length for 2m mobileantennas.The 5/8 wave antenna is typically fed against a ground plane (car roof)andis usually matched with a tapped inductor.
-set lengthof dipole to multiples of 1/4 wave on each side (e.g. 0.5, 1.5,2.5, etc.). Notice how these lengths produce an radiationresistance(impedance) close to 100 ohms. The patterns of these are madeup ofmany lobes (cloverleaf pattern).

NEC ModelLibrary
The following files and links point to NEC/AO/YO models of various Hamantennasthat I have simulated and/or tested over the past 30 years as anantennadesigner. The NEC files may be used with any of the NEC-2 or NEC-4programssuch as 4NEC2, GNEC or cocoaNEC, however some of them with taperedelementsmay only be simulated accurately by NEC-4 or other MININEC-basedsoftware.These models will indicate in the CM lines if they need to use NEC-4 or4NEC2.These models have varying degrees of accuracy. Some may be very closetoactual performance. Others may only be an estimate. They are for you,asthe experimenter, to use and improve. This list will grow asI checkeach file before uploading, so check back often. Have fun!

The VHF antennas shown above include the 'raw' element lengths. Thatis, the element lengths are those used with a wood or plastic(dielectric)boom or supported above or below a metal boom with an large insulator.Toconvert these raw lengths into actual lengths used when passed throughthecenter of metal booms, you need to add a correction factor, based onwhetherthe element is insulated and passes through the center of a metal boom,oris shorted directly to the metal boom with a clamp.
Free Yagi Antenna Design Software
If theelement is insulated when it passes through the metal boom, thecorrectionfactor is approximately 1/4 the diameter of the boom. Forexample,for a 36' (raw length) insulated element passed through the center of a1'metal boom, the correction factor is 0.25', so the actual length shouldbe36.25' when built.
