Some authors quote Return Loss as a negative number, and this convention is still widely found in professional radio communication and telecommunications literature. This “gun antenna,” otherwise known as the Disk-Yagi, got publicity to DIY-ers thanks to a video blogger under the nickname KREOSAN. Long yagis are commonly used from the 144MHz amateur band to the 2. 8 to 21. The configuration of this Yagi antenna is known as a “Plumber’s Delight” (everything is connected together and grounded), a Gamma Match will be the simplest to construct. 6 Watt Baofeng UV-9G to 35 Watts!

In order to transform this piece of coaxial line into antenna you need to remove a bread shield in the middle of the coax, and solder braid shield to a central conductor at its both ends (cf. This is a handy calculator for trying to create a Folded Dipole feed section for a multi-element VHF/UHF array, like a Yagi. Michael ZS1RJQ. The Yagi-Uda. Listed under the Antennas/Antenna Calculators category that is about Antenna design calculators. The calculator on the right illustrates the Three-Element Yagi. 71Ω. Feet Inches. 66 on the calculator the antenna will be too short. Jul 17, 2020 · I've recently started comming across a popular antenna design in the DIY community, which looks similar to the traditional Yagi-Uda antenna (large reflector at the back, driven element in the middle and several directors at the front), but instead of straight elements perpendicular to the direction of the antenna, there are coaxial discs. SWR curve of the HYS Yagi antenna that we used. 6 dBd) and Long Boom Lengths (2. All the single band ones are CLEARANCE COST, Over the past 5 years, I have gotten many emails regarding the Yagi . Learn about the construction materials, gamma matching and beam width of this antenna type. Using the DL6WU formulae, this results in a 14 element yagi, with a gain of over 13 dBd. Change this to whatever frequency you like. Feb 6, 2018 · Yagi Calculator is a Windows program that also runs well on Linux, Ubuntu 8.
