Quagi antenna design 7: 1. The antenna, which is usually built with little more than hardware store materials, became popular in many parts of the world. Quagi antenna is designed using 4NEC2 tool. Initial tests showed an SWR around 3:1. By moving DI as close as possible to the driven element, I lowered the SWR to about 1. (Reflector is 1 wavelength + 5%) The driven element is direct fed with 52 ohm coax. 2 Meter 10 Element Quagi Antenna This antenna was designed by N6JSX Kuby for Transmitter hiding. It’s easy and noncritical The 1296 MHz Quad-Yagi (Quagi) uses a quad driven element and a quad reflector. It is just as easy to reproduce as the smaller eight-element quagi, but it of- fers nearly 15 dB gain over a dipole (dBd). Jun 5, 2025 · Dimensions and plan to build a W5UN EME quagi antenna 4 elements 50MHz Quagi Total Boom Lenght is 3 m. The answer is the 15-element array to be described. ABSTRACT: A Quagi antenna is a variation on the venerable Yagi-Uda. A Quagi antenna is merely one of the most interesting amateur antenna designs to come down the pike in recent years. Antenna is designed and analysed its performance by varying elements spacing. One sixteenth inch brass welding rods can be used as directors on a quagi antenna. Fitting the requirements of directionality, high gain, and portability. A third article, describing Quagi antennas for 1296 MHz, appeared in the August, 1981 QST. The original design was republished in amateur radio publications in countries as diverse as the former Soviet Union and India original quagi design is well known, and numerous amateurs have asked if the quagi principle could be applied to a super-long antenna for 432-MHz work. If what you want is a good, easy-to-build antenna for 144, 220, or 432 MHz, the quagi may be your answer. Any non-conductive boom can be used to hold the . Quagi antennas frequently have between eight and fifteen elements. (1 Wavelength at 1296 MHz). A conventional Yagi may well deliver more gain per pound or per square foot of wind load at 20 meters. I did not use a 1:1 balun. Even at 50 MHz, a quagi of this design would be too big for the author’s portable expeditions and contest work. The typical quagi antenna design has one square reflectors and a square director element centered on the same central line as the yagi elements.
