Radome

Basic function of a radome is to provide protection for a radar antenna from outside environment while simultaneously minimizing impact on electromagnetic properties. The radome can improve overall system performance, reduce down-time, extend radar antenna‘s service life while decreasing maintenance costs. Addition of a properly designed radome provides a huge benefit to antenna system facing severe weather conditions. 

ELDIS radome’s individual segments (panels) have a sandwich structure with a foam core and high-strength laminate layers. The top layers are fully weather resistant (sunlight, hail, etc.), the individual panels and the entire array are mechanically rigid enough to withstand strong winds and withstand significant snow and ice load. Sandwich panels and their joints are radio-transparent, not to negatively affect the radar‘s operation. The panels are bolted together to form a spherical shape. The panels at the base have a molded flange for attachment to a fixed part of the tower or other base. To unify the radome installation procedure, an anchor ring is used to fasten the radome to various types of tower or other base structures.

Key features

Function of the RADOME
  • protects antenna from damage caused by severe weather conditions (rain, snow, wind, hails, etc.)
  • improves the aerodynamics of antenna system and reduces its wind drag, which can improve the performance and efficiency of the radar system
  • provides protected environment for any electronics located near the antenna
Functional characteristics

The technical parameters of an antenna radome will depend on the specific application and the requirements of the antenna system.
