Figure 18-8 shows the construction details for a six-element 2-meter Yagi beam antenna. This antenna is built using a 2 X 2-in wooden boom and elements made of either brass or copper rod. Threaded brass rod is particularly useful, but not strictly necessary. The job of securing the elements (other than the driven element) is easier when threaded rod is used, because it allows a pair of hex nuts, one on either side of the 2 x 2-in boom, to be used to secure the element. Non threaded elements can be secured with RTV sealing a press-fit. Alternatively, tie wires (see inset to Fig ) can be used to secure the rods. A hole is drilled through the 2 x 2 to admit the rod or tubing. The element is secured by wrapping a tie wire around the rod on either side of the 2 x 2, and then soldering it in place. The tie wire is no. 14 to no. 10 solid wire. Mounting of the antenna is accomplished by using a mast secured to the boom with an appropriate clamp. One alternative is to use an end-flange clamp, such as is sometimes used to support pole lamps, etc. The mast should be attached to the boom at the center of gravity, which is also known as the balance point. If you try to balance the antenna in one hand unsupported, there is one (and only one) point at which it is balanced (and won’t fall). Attach the mast hardware at, or near, this point in order to prevent normal gravitational torques from tearing the mounting apart. The antenna is fed with coaxial cable at the center of the driven element. Ordinarily, either a matching section of coax, or a gamma match, will be needed because the effect of parasitic elements on the driven element feedpoint impedanceis to reduce it.
I enjoy searching for hidden transmitters. I did my first fox hunt more than 15 years ago and built a tape measure yagi antenna for that purpose. That antenna served me well and not only sniffed out hidden transmitters, but also located an individual causing malicious interference to our local repeater. Our club was looking […]

Four element, two meter beam, elements can be tubular aluminum, solid aluminum, or for low terrestrial noise, use fiberglass elements. This beam may be installed vertical, or horizontal.For optimum performance and gain, feed with BUX COMM "VBALUN." Four element, six meter beam, elements can be tubular aluminum, solid aluminum, or for less terrestrial noise, use fiberglass elements. This beam may be installed vertical, or horizontal.
A great video by N4CCB where he shows a portable hexbeam antenna he recently built, describing the components that are required to build one and three homemade hexbeam antenna projects

K0EMT VHF/UHF/HF? X-Beam Antenna VHF/UHF X-Beam Construction Notes (and HF see update below) -- k0emt I sat down and drew out what I did and thought I'd pass on what I did/found out. The design is from The 1993 ARRL handbook that was given to me by wd0hbx. The x-beam was originally intended as an HF mono-band beam. I used the formulas to build it for 6m. It also happens to work out really well for 2m & 70cm use as well.

The radiation pattern (or) directional pattern is one of the most desirable characteristics of antennas in all communication and radar applications. The directional pattern of an antenna plays virtual role in selecting an antenna for a specific application. According to user defined application, the radiation pattern shapes are numerous in number. The work…

Using Active Integrated Antenna (AIA) instead of the conventional sub-system designs of individual components will provide a system designer with more features and enhance performance. This book explains how active integration and co-design between the active components (amplifier, oscillator, mixer, diodes) and the antenna can provide better power transfer, higher gains, increased efficiencies, switched beam patterns and smaller design footprints. As new antenna designs will require closer integration with other radio electronics, AIA are expected to be used in future wireless terminals. The book introduces the fundamental aspects of AIA and discusses in detail the various types of AIA, such as oscillator, amplifier, mixer, transceiver, frequency reconfigurable, on-chip and on package, as well as non-foster AIA covering various frequency bands and wireless standards. It presents co-design procedures for AIA applied to multiple-input-multiple-output (MIMO) front ends as well as examples of narrowband and wideband designs. This is the first book to elaborate on AIA design with detailed step-by-step tutorials and the use of software packages (provided in an accompanying CD). It contains real world cases and illustrations, and is a must-have title for practicing and research engineers.
