Simple Ham Radio Antennas: Ham Radio 10 Meter Loop Antenna, Part 1 of 4. Post #372.


One of my favorite amateur radio activities is making my own wire antennas out of available materials. Among the antennas in my modest antenna "farm" are full-wave loops for 80, 40, and 20 meters, usually made out of #12 AWG household wire and fed with RG-8X coaxial cable. My 80 meter loop is configured as a delta loop with the apex of the loop set on a Norfolk Pine branch approximately 50-feet/15.24 meters above ground. I can feed this loop with either coaxial cable for single band use or with 450 ohm ladder line, a 4:1 balun, and a transmatch for multiband use. The one loop I didn't have was one for 10 meters. I came across this excellent four-part series by Dave Tadlock (KG0ZZ) on making a loop antenna for 10 meters. I decided to incorporate Dave's ideas in making my 10 meter loop, including the important planning phase, as described in part 1. Although it may appear tedious to proceed this way, I found having a clear idea of what you want the antenna to do is a big help in avoiding mistakes. If you follow Dave's guidance, "Murphy's Law" will not be a concern. Parts 2, 3, and 4 will arrive shortly. Have fun...I did.
