Hi-Z 8A Eight Element Array System

     These are ultra high performance mono band arrays (160 or 80 meters). The Hi-Z 8 is a unique array with all elements active in a circle which provides stellar RDF (directivity) performance. This design provides the best performance in the least amount of space. The RDF and Front to Back ratio of the Hi-Z 8 array is the best available to date commercially. This design easily outperforms long Beverage and various loop antennas in many ways. This array utilizes the Hi-Z amplifiers at each element.

    The Hi-Z 8A is still the same basic system that dominates the top band receiving arrays. Functionally the same as the Hi-Z 8, the 8A has the pre-amp external (post) phase controller, making the insertion of filtering where and when required easy and quick to implement.

Hi-Z 8-160                                                 Hi-Z 8-80

     The Hi-Z 8-160 is based on a 200 foot diameter circle. The Hi-Z 8-80 meter array is based on a 100 foot diameter circle. While this design appears to have some rather large side lobes, they really are not very significant to noise or off axis interference pickup. These lobes are very low elevation angle responses and as such do not respond to local signals or noise.
