101-68-10-X-03 Series, 450-512 MHz, UHF Broadband RF Antenna
These robust, high-powered antennas are designed to complement our wide bandwidth multicoupling systems covering the frequency range of 450-512 MHz. Through a true corporate feed design, equal in-phase power is distributed to each radiating element. This method insures excellent vertical pattern control and shaping, low loss, and beam-tilt that does not vary over the operating bandwidth of the antenna.

This patented design was achieved through the use of a 5-chamber extrusion which acts as the central core of the antenna and provides a low impedance direct ground for lightning protection. The rugged fiberglass radome and its interface to the mounting tube have survived extensive wind-tunnel testing at wind velocities exceeding category 5 hurricane forces. Antenna data files are available in TIA-IS-804 format for inclusion in popular commercial propagation analysis programs.
