Measured outstanding low SWR from 144 MHz to 146 MHz. Less than 1.1 on whole band. 20m 2-element light-weight Yagi. This antenna was designed for the CQ WW CW 2009 at EA8URL. The Bavarian Contest Club took part in the M/M class with a team of German operators. The antenna plans included a second 20m antenna to work both USA and Europe in the day time. Because EA8URL has only one 20m yagi we had to bring another 20m yagi with us.Jan 11, 2015 · OWL G/T models boast the highest gain per foot of boom and, consequently, class-leading G/T figures. OWL G/T antennas marry a high gain, low-impedance Yagi design with a folded dipole wide-bandwidth feeder cell which yields a direct 50-Ohm impedance. Making these beams perfect for stacking was a key design objective. For a further reducing of the weight the directors can be made of 2,4 or 3,2mm rods, 4mm is possible, of cause. If you want to built the Yagi with 6mm-elements and conventional boom, I have listed the dimensions in the table, too. This calculator is designed to give the critical information of a particular beam antenna, in this case a three element Yagi, for the frequency chosen. Enter the desired frequency then click on Calculate and the optimum values for that combination will be displayed in feet, inches and fractions of inches, and in meters.Spacing of each elements from the reflector as follows (WL = 2.0547 in meters) Reflector to Driven element = 0.125 X WL = .256838m (or 10.1117″) Reflector to Director 1 = 0.250 X WL = .513675m (or 20.223″) ... 24 thoughts on "Homebrew 5 Element VHF Yagi" KG4AKV says: February 23, 2012 at 10:04.

Check out my Gamma Match page on how to build one .by Brian Beezley, K6STI, Issue 39, October 1993 Here's a design for a 5-element beam on a 23-foot boom with an unusual combination of performance characteristics. This Yagi comes within 0.2dB of the maximum gain possible on the boom length while keeping all back lobes 20dB down. This performance combination is very rare.Approximately 13 feet of element stock will be required. Build the Reflector first, make it 40″ long. Find the middle of the length, drill and tap a hole for a 6-32 screw. The Driven Element will be ~5% shorter than the Reflector or 38″ long.
