Hi, friend. very good. conditions at 6 m. I would like to build a loop aerial to work digital mode. like FT8 or SSB since a summit, it would be something great. I’d like you to share a plan or diagram of a light loop antenna that’s easy to assemble.
Have a look at the video from Akira (Mot) JP1QEC for an interesting 6 m delta loop with a transmission line matching section. Antenna and matching section made from speaker cable. https://www.youtube.com/watch?v=FOLJgFq9MZA
Here is a simple, cheap and effective loop antenna design with horizontal polarisation. I have made versions of this for 2m, 4m and 6m, which I have used successfully in various portable situations. They are super light and take about an hour to make.
