Topband: K6STI low noise receive loop

And, in my case, Don, I simply need to put up an antenna that's: a) more efficient than my vertical and b) fits within the confines of my property....having any noise cancelling or nulling is a plus but not as important as a and b (b being the huge limiter)

On 160 meters the elevation pattern shows max gain at 44 deg and 43 deg on 80 meters.  RDF is not spectacular, but depending on where the noise is coming from (as well as the signal of interest) it might do well.  Looks like it does best when noise is arriving at a very low angle, or at a very high angle.
