Ham Radio - 80 160 meter magnetic loop transmitting antenna

If you want to work stations on 80 and 160 meters, but have little space to erect an antenna, try this fairly simple magnetic loop antenna from Kevin Loughin (KB9RLW). Just follow Kevin's simple instructions: "This is my 6 foot diameter magloop for 80 and 160 meters. I create a two turn outer loop to get down to 160 and it works very well. I checked in to a local 160 meter net and 4 out of 5 stations could hear me. Pretty neat for a 6ft antenna! There have been a few questions about the capacitor I used. Measured on my old Heathkit RLC bridge, it looks to be around 20-700pf with about 1mm plate spacing. I've pushed it to 40 watts without an arc. I also built a mini loop out of junkbox parts for fun. It's 1 foot square and works really well. https://

Here's an intriguing way to get on 160 and 80 meters with a stealthy magnetic loop antenna.  In this video, Kevin Loughin builds, erects, and uses a 6-foot/1.829 meter diameter magnetic loop for 80 and 160 meters.  As Kevin relates, " I create a two-turn loop to get down to 160 and it works quite well. I checked into a local 160 meter net and 4 out of 5 stated they could hear me." The loop is made from copper tubing and uses a 20 pf to 700 pf capacitor with about a 1 mm spacing to tune the antenna.  Kevin says "I've pushed it to 40 watts without an arc."
