The calculator creates equal spacing between the elements, which achieves a balance between good bandwidth performance and a decent 50-Ohm match. Yagi Uda Antenna Calculator REQUIREMENTS DESIGN DATA FOR YOUR YAGI Note It is quite possible, that other calculators deliver slightly different results. Long yagis are commonly used from the 144MHz amateur band to the 2. Yagi Uda Antenna Calculator. Share your thoughts The webmaster does not read these comments regularely. This calculator can be used to design a Quarter Wave Ground Plane antenna, with radials. The calculator (above right) provides dimensions in both USImperial and Metric. Here is another DIY Yagi antenna design for 1200MHz and also suitable for 2400MHz VK5DJs YAGI CALCULATOR Yagi design frequency 1200,00 MHz Wavelength 250 mm Parasitic elements fastened to a non-metallic or separated from boom Folded dipole fully insulated from boom Directorreflector diam 4 mm Radiator diam 3,5 mm REFLECTOR 121 mm long. 7 m boom length for the lower 144 MHz SSBMGM band, in PDF Format. The commercially made Yagi could detect the signal, but it was too weak to get a picture. Yagi Calculator is a Windows program that also runs well on Linux, Ubuntu 8. Additional benefits of patch antennas is that they are easily fabricated making them cost effective. ) that remains. To get a really good, clear picture as the satellite neared the horizon you needed a circularly polarized (CP) Yagi. This antenna wavelength calculator can be used to determine the physical length of an antennas electromagnetic wave in free space. During 1925-1929, he published his research in about a dozen articles in the Journal of the Institute of Electrical Engineers in Japan. Input power limited by feed line only. Just a three elements are required; Reflector, Drive Element (dipole or loop) and a Director gives about 5 dB gain. The formula and essential studies related to Yagi Antenna calculation are also explained here with examples. The two elements yagi-uda is the smallest one among the yagi-uda familly. A quarter-wave choke of coax is grounded at the socket. l L 2. I'm getting ready to build my own 4 element yagi antenna , using the calculator on this website. Some are based on look-up tables, some completely hide their algorithms. For each antenna gain and impedance is calculated with and without ohmic losses, upper and lower lines for each entry in the table.
