Broadband | Base Station Antenna

100-400 MHz FXDP100X4 (1Y04650)

Construction Details: The antenna consists of an aluminum coaxial dipole covered by glass epoxy.

Within each semi-dipole there is a coaxial line shorted at the end. The coaxial line of the upper semi-dipoles produce an appropriate impedance to provide broadband operation of the entire antenna. The coaxial line of the lower semi-dipoles generate high impedance which attenuates to negligible values the currents that inevitably flow within the support pole.

These supports further provide a balancing that ensures that the characteristics of impedance of the two coaxial lines remain effectively constant even in the presence of shack, vibration, etc.

Installation: An optional mounting bracket is available with a mounting flange of 4.5 in. (114.3 mm) equipped with protection for the connector against the elements.
