The Model 504 family of rosette dipole log-periodic antennas is designed to provide high gain, high front- to-back ratio, steerable performance in a compact area. The 504 finds wide application for ground-air and shore-ship circuits, where the other end of the path is mobile, and good long-distance coverage and gain are needed.
Each curtain of the 504 acts independently—in effect, simultaneously forming four independent beams, 120° wide. Further independence and flexibility are provided by using transmitting or receiving multi couplers, allowing several operators to use any one beam simultaneously.
