I used AlMg3 welding rods for the radials. I used the to calculate all measurements. Using the DL6WU formulae, this results in a 14 element yagi, with a gain of over 13 dBd. For this antenna I bought an square bar (15x15mm), made of aluminium, length 1 meter.Īt one end I mounted a standard available mast mount, leaving about 90cm for the actual antenna. This material is also easy to drill, saw and grind.
Lightweight Construction Because of low weight and easy handling I mostly use aluminium to construct VHF/UHF antennas. In the past I built a couple of 2m beams using DL6WU’s design, so I decided to use this again, now for my 23cm yagi. Many other designs are actually just small modifications of the DL6WU formulae. Guenter Hoch DL6WU has researched this subject for decades, nowadays his design formulae are accepted throughout the world in both commercial and home made antennas. Design criteria There are lots of designs available for yagi antennas. To achieve a more steady uplink, I decided to build an antenna with a bit more gain, at least 6 dB extra compared to the HB9CV. Although this antenna works nicely, its gain just isn’t enough when their 23cm preamp is broken (which, unfortunately, is the case most of the time). My 23cm yagi antenna, in fixed position to the local ATV repeater.In the previous Winter I built a for 23cm for my uplink to the local ATV repeater PI6ATV. It uses the graphs and principles developed by DL6WU and printed. Yagi Calculator is a program to assist with the design of long yagi antennas. Free Online Engineering Calculator to find the Dimensions of a yagi Uda Antenna for a given Frequency Range and Length. The DL6WU Yagi is highly regarded as being easy to build with. Circuit simulator and PCB design software. Yagi Calculator is a program build to produces dim. Provision for entering the dimensions of an existing DL6WU antenna for optimization through an external program or to gather information on its gain, beamwidth etc. 
Different size materials for boom and elements are catered for as are different methods of mounting.Calculation of the element length and element spacings of a yagi for a particular frequency.Here are some key features of “Yagi calculator”: The DL6WU Yagi is highly regarded as being easy to build with repeatable results, broad bandwidth and a useful pattern. Long Yagi are commonly used from the 144MHz amateur band to the 2.4GHz band. Yagi Calculator is a program build to produces dimensions for a DL6WU style long Yagi antenna.
