As the loop is so small the SWR changes very considerably with changes of nearby objects (such as the opporators hand!) and positioning (e.g. moving the loop while nulling noise). As a result of this and its small size its probably not worth transmitting through this loop but it does work well for receiving. I found a ca. 300pf tuning capacitor made the mini loop resonate between 160m and 80m. I set the antenna on top of an empty large plastic storage container and moved it around for nulls.
A camera tripod (see photo below) allows for easy adjustment of the loop. Sometimes you have to both rotate and slope the loop to find a good null in the noise. It's a great little antenna and the null provides a wonderful drop in noise to bring in the DX!
I love listening on 80m in the winnter especialy at christmas times and usually spend a few days at my parents QTH listen at night or early morning while everyone else is asleep! I have tried many antennas at this QTH. This little loop got me listening on the SSB DX for xmas 2006. One particular evening I had a lot of fun listening to the North African EA9IE work the world (well a lot of North America)! The log-book entries show what I could hear on this little loop (inside the house from my second story room, location in Sussex, UK).
