|A new, fully illustrated catalogue has informative, explanatory technical and application information for use as a reference handbook by system developers and operators.
Six pages of photographs demonstrate a wide variety of applications. Security and surveillance applications illustrated include tri-band harmonic radar antenna for security sweep equipment and omni and switch sector antennas for video and telemetry from helicopters. For wireless local loop applications the actual radiation pttern for a typical base station antenna illustrates the benefits of null-fill below the horizon, electrical down tilt, minimal front-to-back ratio and side lobe suppression. Other sections cover mobile and data communications, antennas for satellite links and special projects. Eight pages of technical information help operators select the type of antenna they need showing the relationship between gain and beamwidth, gain and size, frequency and size. Antennas included are low profile, flalt panel, sector, dipole, omni, helix and broadband.
