Antenna Topics: A simple 40 through 10 meter delta loop. Post #192
A simple 40 through 10 meter delta loop. One of the quietest and most versatile antennas I've used over the past few years has been a 40 through 10 meter delta loop fed with 450-ohm ladder line. Used with a 4:1 balun, an antenna matchbox (i.e. "tuner), and a few feet (meters) of 50-ohm coaxial cable, this easy to build antenna will give you hours of both local and DX contacts. I built my original 40 meter delta loop with tuned feeders back in 1977, shortly after I passed my novice amateur license exam. Since space was at a premium (small backyard), money in limited supply (I was just starting my broadcast radio career after time in the Air Force), and I was recently married, extra funds for a tower and a super sophisticated rig were unavailable. Like many of my fellow amateurs, I depended on wire antennas, used rigs, and basic designs to work the world. My first rig was the venerable HW-101, a rig I must have rebuilt several times. Anyway, I found simple antennas,
