Simple Ham Radio Antennas--How to build a Delta Loop Antenna. Post #675.

If you're having trouble viewing this video, please insert this address into your browser search box: Exceptionally well-done video from Hiram Vasquez on how to build a Delta Loop Antenna for 20 meters. Hiram uses a simple Q-Match to make the antenna resonant at approximately 50 ohms--perfect for any 50-ohm coaxial cable you may have around the shack.  Most of the materials can be bought at the nearest hardware store or home improvement center.  The object in back of Hiram is the rope he uses to raise and lower the 20 meter Delta Loop.  The antenna is simple, elegant, and easy to build.  If you want coverage between 20 and 10 meters, replace the 50-ohm coax feedline with 300 ohm television twin lead or 450 ohm ladder line in conjunction with a 4:1 balun and a short length of 50 ohm coaxial cable, which plugs into your antenna transmatch (i.e. "tuner").  This Delta Loop is bi-directional and exhibits some gain.  For the latest Amateur Radio news and eventes, please check out the blog sidebars.
