Square 4 Element Receiving Array System

All New, only One Model Covers 60 or 80 Feet Per Side Element Spacing


     This New Version controller was designed to connect 4 shortened vertical antennas using Hi-Z amplifiers into a directional receiving antenna. This all new SMD parts layout and unique circuit configuration using Tri-Phase combining for advanced accuracy phasing and amplitude stability. This unit uses only two delay lines and provides a form of time delay phasing that provides more than one band coverage with the Hi-Z elements. This unit was optimized for the 160 meter amateur band but can be used from the middle of the broadcast band to over 30MHz. A typical 80 foot square layout of 20 foot tall elements and Hi-Z amplifiers can provide as much as 12.1 dB of Relative Directivity Factor and 30 dB of front to back ratio on 160 meters. Of course the best performance depends on the accuracy of the antenna layout, the accuracy of the connecting and phasing cables, and any interfering nearby structures. It also requires two wires to switch between the 4 available directions and two for +13.8 V and power ground.
