K4IQJ

--- Dedicated to low-band receiving antenna design using arrays of K9AY loops ---... In my location with poor ground conditions, the K9AY loop seems to offer the best performance. This site discusses the design and implementation of 2- and 3- and 4- element endfire arrays of K9AY loops. Design of these arrays focuses on optimization of the Receiving Directivity Factor or RDF attributed to W8JI (See the Low-Band DXing book by ON4UN).
