Dielectric introduces 1.4GHz circularly polarized antenna for mobile media

Dielectric Communications now offers a new L-Band, 1.4GHz high-power, circularly polarized broadband antenna to support the international mobile media market. It leverages the company’s pylon antenna technology by featuring both azimuth and elevation pattern versatility in a single “common box” enclosure.

Dielectric’s common box approach improves network-planning capabilities by allowing broadcasters to adjust the transmission pattern without changing the mechanical specifications of the antenna design. Network planners can perform a comprehensive analysis of all possible site locations that can accommodate a single specific set of mechanical specifications. The antenna’s pattern versatility then gives network planners the ability to blanket a region with the most effective coverage.

The low-wind-load construction of the new antenna allows for either side- or top-mounting and provides an excellent axial ratio, a 1kW to 4kW input power rating, gains from 15dBi to 19dBi, a VSWR of less than 1.1:1, and 10kW to 24kW ERP/polarization.
