The EB-425 EGGBEATER antenna offers performance characteristics for specialized fixed and mobile operations within the 310-510 MHz frequency range. The EGGBEATER produces a smooth, horizontally polarized omnidirectional pattern at the horizon. Above the horizon, the hemispheric pattern transforms to RIGHT HAND CIRCULAR polarization, making it a natural for aviation, ELINT, MILSATCOM or other specialized use. No rotation or steering is required, producing instantaneous communications in all directions. The EGGBEATER's rugged, weatherproof construction suits mobile and marine applications as well as fixed, land based installations in hostile environments. Operations with little room or budget for larger antennas will experience a new standard of performance with the EB-425.
