Broadband Dipole Antenna
Model truly broadband dipole antenna which provides excellent performance over short- medium-range circuits. height configuration antenna were chosen provide high take-off angle radiation frequencies optimum short-range communication take-off angle radiation higher frequencies necessary longer-range communications. take-off angles used short- medium-range communications, azimuth pattern essentially omnidirectional. This provides great flexibility makes applicable most communications requirements. Broadbanding achieved without resistors tuning units full antenna efficiency, with valuable power radiated rather than lost tuning devices. towers vertical. This very important consideration both installation maintenance. Towers safely guyed prior curtain installation. Once erected, curtain lowered time independent tower guying. Compared with long skewed towers, short vertical towers much quicker install, safer climb, easier maintain. uses same high-quality, exhaustively tested components materials featured antennas. radiators, feedlines, catenaries Alumoweld, wire composed high-strength steel core highly conductive, corrosion-resistant welded aluminum coating.

Fixed station antennas traditionally have used catenary drop assemblies fiberglass excellent dielectric tensile strength properties. Field experience, however, shown that minute, difficult-to-detect flaws material, burning, small nicks incurred during installation result catastrophic structural failure deterioration when stored long periods high temperature high humidity. antennas eliminate risks stemming from poor structural qualities fiberglass using Alumoweld catenaries, segmented fail-safe insulators.
