Solutions For Outdoor Installation

The MVG protective radomes are designed to fit Dual Ridge Horns, allowing outdoor installation with minimum impact on electrical performance. The materials and coating employed provide hydrophobic properties and good UV stability, low relative permittivity and low dielectric loss, therefore offering an effective protection in outdoor conditions and good RF transparency. The radome enclosures are also equipped with pressure equalizing vents to reduce condensation caused by rapid changes in tempe-rature, while preventing water and dust ingress.
