Cubical Quad Element and Antenna. home up. Delta Loop. Noise and Loops. Gain of Loop Element. How or why does a Quad (or any other antenna) develop gain? Gain does not come from antenna area or size. Aperture is a function of gain, gain is not a function of aperture. Gain comes from compressing radiated power into a narrower area without increasing losses more than the compression or focusing. A Cubical Quad loop can produce either vertically polarized or horizontally polarized radiation depending on the way it is set up and on the point in the loop where the feed-point is set. A typical Cubical Quad is usually oriented either as a square loop with two arms parallel to the ground while the other two are vertically oriented Back in 1951 Clarence Moore a Christian Missionary and engineer at a radio station high in the Andean mountains of Ecuador, developed a two loop antenna that he called a Cubical Quad. He developed this antenna to resolve issues caused by large coronal discharges while using a yagi beam antenna in the thin air of higher altitudes Dieser Antennentyp wurde im Jahr 1942 hoch im Anden-Dschungel in der Nähe von Quito in Ecuador für die seit 1938 betriebene Rundfunkstation Radio HCJB, von Clarence C. Moore (W9LZX) einem der Stationsingenieure und Funkamateur, entwickelt

Die Verwendung von Quad-Antennen im Amateurfunk geht auf Clarence Moore, W9LZX, zurück. Speziell als 2 Element Cubical Quad mit Strahler und Reflektor war diese Antennenart als Drehrichtstrahler in den 50'er und 60'er Jahren populär. Alurohre waren teuer und oft schwierig zu bekommen. Die Quads konnten dagegen aus billigem Bambusrohr und Draht gefertigt werden. Eine stabile, wind und. The standard formula goes like this: On a standard Cubical Quad Antenna each side is 1/4 or.25 wavelengths long this gives you about 1.2 db gain over a dipole (yagi driven element). If you make the vertical section of the quad.172 wavelengths long (shorter)

Cubical quad antenna includes: Cubical quad antenna basics Quad beam antenna with reflector & director 2 metre cubical quad design The Cubical Quad or Quad antenna has traditionally not been as widely used as its more popular cousin the Yagi. However the cubical quad beam antenna is able to provide some advantages in a number of circumstances In the design of Cubical Quad antennas there are several competing goals or constraints that control the final results. Three important ones are Forward Gain, Front to Back ratio, and Source Impedance. Other factors are material related - Boom Length, and number of elements. Variation Die Antenne ist sehr breitbandig, kommt aber auch an ihre Grenzen, vor allem, wenn man bei der Nutzungsbandbreite übertreibt.

Cubical quad antenna The cubical quad antenna consists of multiple squares placed one after another. The first square is the reflector, the second one is the driven element and all other squares are directors cubical quad. Moore's original antenna was put to use on the shortwave bands, but UHF and VHF operators were quick to find other applications for this beam antenna. As beams go, the cubical quad is relatively easy to make, gives good performance and is relatively forgiving of small errors in design and construction. And, element for element, it even gives a bit more gain than our old friend.

I made another antenna; a 70cm Quad antenna, and it works like a charm! The bad thing about quads is that they are full wavelength antenna's, which in HF normally means; LONG ANTENNAS! The good thing in this case is that a full wavelength in the 70cm band means; a 70cm (27.6 inches) long antenna! In a quad this means that every side is 17.5cm (6.9 inches) long, almost. 2 element Cubical Quad. The two element quad has a very good reputation. If you are limited in space a 2 elements quad could be what you were looking for. A quad has a smaller turning radius that a yagi it has a lower noise level and a slight higher gain. Probably the best solution for its size. Another advantage is that you still don't need a big rotator a small TV rotor beneath this antenna. Conceptually, the multi- band quad is a simple antenna, with separate driven and reflector loops for each band. In the case of the five-band, 20- through 10-meter quad, the driven and reflector arms each support five concentric wire loops

This two-element Cubical Quad antenna is designed for use on either the 10-meter ham band or the 11-meter Citizen's Band. When all was said and done, my SWR readings were 1.3 to 1.7 on the 10-meter band. At one point during the tuning phase, I had a reading of 1 to 1 at about 29.5 MHz. I tried to stay with an age-old design but also used commercially available parts. This kept the weight. Every element of a Cubical Quad antenna is a full wavelength long.

Six Meters ARRL ANTENNA Vol 5 COMPENDIUM contains an article I wrote providing details about two portable 6 meters antennas I developed, a two-element quad and a three-element yagi with telescoping elements. Both antennas were designed for easy construction and quick assembly and disassembly. The quad provides a measured gain of 4.2 dB over a dipole and the yagi 5.8 dB over a dipole Lightning Antennas was created in 2010 by the former lead manufacturing engineer at Signal Engineering, a Californian manufacturer of Quad Antennas for the Citizen Band for more than 15 years. SE discontinued manufacturing antennas in 2009 and those 15 years of expertise are now being capitalized by Lightning Antennas which is poised to pair a proven successful technology, the Quad.

Two or more quad loops, only one of which needs to be fed by the coax, are used to make a cubical quad antenna. If only this one element is used, then the antenna will have a figure-8 azimuthal radiation pattern (similar to a dipole). The quad loop antenna is preferred by many people over a dipole for two. Model: Cubical Quad Antenna Hy-Quad 244 - Hy-Gain Electronics: Material: Special material, described in the notes. Shape: Miscellaneous shapes - described under notes. Dimensions (WHD) 7740 x 7740 x 2440 mm / 304.7 x 304.7 x 96.1 inch : Notes: Heavy swaged aluminium tubing spreaders; two elements tri-band quad designed to operate on 10, 15 and 20 meters; separate pre-tuned gammas; imput. Cubical quad antennas are known for their high forward gain as far as antenna arrays go. The added gain of these antennas as compared to, say, Yagi parisitic arrays of the same number of elements is due to the fact that the cubical quad elements are a full wavelength (or multiple wavelengths) as compared to the Yagi's half wavelength elements. The full wavelength elements of the cubical quad.
