This article was obtained from VE3GK experiences, constructing and designing full size, single band stacked yagi antenna arrays, special rotating, electric powered, telescoping towers and rotators. All the test results are from first hand experiments. VE3GK kept a record of these experiments and construction details and offer them for your interest. HISTORY I started out
The following are construction details of a 5 element 20 meter monobander antenna originally published by VE3GK. However, this particular yagi was run through a computer program and performed very well. It was also scaled to 70 cm on a test range by the late VE3UD, Bud Punchard and the results compared with the computer
G3SYC designed this antenna in about 1990. The antenna works best between 15 and 20 feet off the ground, and can be worked some nice dx with it. The antenna is easily folded up and stored away when not in use, and has a minimal impact when erected . SPACING Inches ELEMENT LENGTH (Inches)
Even if outdated, is still a good program to calculate and desing yagi antennas elements dimensions, sizing and spacing. I’ve used it to verify some antenna plans I’ve found on the net. It’s particularity is that you at first need to tell the program the size of your antenna and then, you can calculate resonating
The Yagi Designer program was first developed in 1992 on a DEC-Vax 3100 and written in Fortran, and the output was graphed in Mathematica 2.0. It has since been converted into a DLL with lightning fast speed compiled in the C language. It was written by a physicist that has always enjoyed dabbling in radio.
The Grid Yagi (or Grid Quad) is a high performance yagi antenna that can be built with readily obtainable inexpensive materials. Described here is a 6 element 2 meter version with a boom length of about 1 wavelength. The boom is made of 11?2 inch pvc pipe, although any suitable material can be used, such
