Topband: Small loop Performance

[steve.root at culligan4water.com]

A lot of us are of course interested in the results of these experiments because the loop is small enough to fit into a typical suburban or urban lot. In evaluating the performance of these antennas it is interesting to hear about one's ability to null out a local Am broadcast station. However that doesn't tell the whole story. How well does it hear pitifully weak DX stations? I've worked with a couple of loops based on N6RK's designs, and while they have deep nulls and work as expectred they also don't seem to produce any usable RF from DX stations. I can hear stateside signals with it but rarely anything weaker. A practical receiving antenna, at least for those of us living in the depths of the Black Hole, has to capture enough RF to produce some audio in the headphones.
