Sometimes the diamond style construction can provide a attractive option for construction. When this format is used it should be remembered that the width of the antenna is equal to the diagonal of the square, whereas when the horizontal square is used, then the width is equal to only bottom of the square. Basic cubical quad antennaĪlthough the format of the horizontal square for the cubical quad is the more obvious format and the more common, it is also possible to turn the square format through 45°. This is normally only achieved at VHF or better still UHF. In some instances where antennas are small enough and the tubing is sufficiently robust, it is possible to rely onth e strength of the tubing alone for the mechanical strength. Often the cubical quad is constructed by having an ‘X’ frame made from insulating material, even wood, and then using this to support the wire or tube that forms the conducting radiating element.

As such the loop forming the element is a full wavelength with each side being a quarter of a wavelength. It is found that the voltages at the ends of the antennas are in phase with one another.Īs a result it is possible to connect these ends together and remove one of the feeders to create the basic quad element. The next stage in the evolution is to retain the two separate dipoles but bend the ends together.
This arrangement in itself gives gain because of the phasing effect between the two dipoles. The basic quad element can be seen to be derived from two dipole elements stacked one above the other and fed in phase. It has been used for some television antennas, but it has also seen a lot of use within amateur radio applications for use at HF and VHF / UHF.Īlthough the cubical quad antenna is not nearly as widely used as the Yagi, it still has advantages and can be used to good effect in many instances. Since its first introduction in the 1940s, the quad antenna has found uses in a number of areas. However the cubical quad beam antenna is able to provide some advantages in a number of circumstances. The Cubical Quad or Quad antenna has traditionally not been as widely used as its more popular cousin the Yagi. Find out what the cubical quad antenna is, how it works, operation, design, etc.Ĭubical quad antenna basics Quad beam antenna with reflector & director 2 metre cubical quad design This clever feature allows for all uses of this antenna to be realized.Cubical Quad Antenna The cubical quad antenna provides advantages over traditional aerials. Please use one of the below jumpers to connect this antenna to your coax.
Please note that the feed point of this antenna is terminals. Power Rating: 1500 W Single Side Band and 500 W CW Robust Design! The Quasar Quad continues the RadioWavz tradition of American made antennas built to withstand the rigors and demands of the amateur radio community.Įasy Set-Up! Each band has been precisely measured so no need for cutting wires just complete the final assemble and you are ready to get on the air! Internally Stackable! Your space is limited, and the Quasar can be internally stacked allowing for room for activities! Ideal for Attics! Quasars are not as susceptible to nearby interference, allowing for clandestine installation in lofts and attics. Less Loss! More efficient than a pair of stacked Yagi antennas, a low angle of radiation means you can do more with less! Greater DB! Typically greater than 2db over a traditional Yagi antenna! That means you would have to have an antenna almost twice the length to get the same performance as Quasar. Lower Noise! Both Quiet and Efficient, the Quasar Quad Experience has lower noise than a traditional Yagi antenna due to its fundamental tube design.
Why is it time for you to purchase a Quasar Quad Antenna from RadioWavz?
