prusaprinters

<p>Template for a 5.8 ghz helical antennas (up to 8 loops).<br/> This template allready takes into account that the copper wire will bend back a bit.</p> <p>The measurements of the template are based on this calculater:<br/> <a href="http://jcoppens.com/ant/helix/calc.en.php">http://jcoppens.com/ant/helix/calc.en.php</a></p> <p>If you don't know what a helical antenna looks like or how to build one please search on youtube or google for more information</p> <p>Usage:<br/> Take a straight 1 mm copper wire bend the first 5 mm to a right angle an stick it into the top hole. Than wrap the wire tight around the template. Allway bend a loop more than you actually nead. Now take your side cutter, cutt of the angle and turn the helix down the template.</p> <p>According to the calculater the reflector hast to be at least 32 mm in diameter.</p> Category: Electronics
