They are typically in stock for every major HF contesting Amateur band and 30 meters; 60 meter array units are available by special order. Four-Square arrays are single band specific, due to antenna spacing and phasing feedline lengths, and for proper phasing and patterns. For manual operation, these relay units require the COMTEK ACB-4A Four-Square Control Console. It is now made to run on 12 to 14 Vdc, allowing easy operation of the four square array with battery emergency or International power sources. A DX Engineering factory-tuned cable feed system for the vertical array (available for your center frequency and sold separately) will provide the best performance.
