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 temperature, while preventing water and dust ingress.
