Fox Hunt Yagi Antenna

prusaprinters

<p>This Fox hunting antenna is constructed using 3d printed element holders (PETG, 20% fill) and easy to acquire material from a hardware store. It is a remix of thingiverse 912567 but optimized for a small, hand held UHF HT rig carried for fox hunt radiolocation. The antenna has a 23 dB front to back ratio and is tuned to the 3rd harmonic of the 2 meter band. This makes an ideal small sized directional antenna that doesn't require attenuation of any kind. A youtube video is available that contains a demo, detailed instructions for construction and performance theory obtained by antenna modeling software:</p><p><a href="https://youtu.be/u0cuMqDpBHc">https://youtu.be/u0cuMqDpBHc</a></p><p>The following code can be loaded into the <a href="http://gal-ana.de/basicmm/en/">MMANA-GAL_basic</a> <strong>antenna definition edit</strong> icon if you wish to play with the antenna design (looks like sheet of text above F in Far Field Plots, or <strong>Edit</strong> menu, Antenna Definition Edit):</p><p><br><code>*</code><br><code>442.29</code><br><code>***Wires***</code><br><code>3</code><br><code>0.0, 0.161, 0.0, 0.0, -0.161, 0.0, 0.00205, -1</code><br><code>-0.176, 0.171, 0.0, -0.176, -0.171, 0.0, 0.00205, -1</code><br><code>0.098, 0.14525, 0.0, 0.098, -0.14525, 0.0, 0.00205, -1</code><br><code>***Source***</code><br><code>1, 0</code><br><code>w1c, 0.0, 1.0</code><br><code>***Load***</code><br><code>0, 1</code><br><code>***Segmentation***</code><br><code>800, 80, 2.0, 2</code><br><code>***G/H/M/R/AzEl/X***</code><br><code>2, 1.5, 1, 50.0, 120, 60, 0.0</code></p><p><br>73, Sandy KB3EOF</p>
