In preparation for some testing I want to do with a Superloop antenna once I can figure out a reasonable way to rotate it, I did some pattern testing yesterday on my 6-foot tuned loop. I used my SDR and a simple hiking compass to take signal strength readings on 4 local and local-ish stations in 10 degree increments, plus extra measurements near the two nulls in the pattern. I was pretty happy with the results, but there were a few oddities (the two nulls for each station were considerably different, the directional patterns were significantly skewed for my hyper-locals, and a few other things). A full writeup is too long for the list and wouldn't be complete without the plots, but I've put up a detailed blog post, including the pattern plots: https://azswdxing.wordpress.com/2015/04/27/gear-pattern-test-of-am-bcb-tuned-loop-antenna/
I haven't seen a lot of full pattern testing data on-line, but it's obviously much more difficult to do for larger antennas. Comments welcomed and encouraged.
