HIREC: Super Hydrophobic Coating for Antenna, Radome and Other Public Infrastructure
Changes in Radio Reception of Satellite Antennas in Rainfall
Radio receptions of 12G Hz-band broadcast satellite antennas at 5 mm/h rainfall were measured in the field. The aperture diameter of the antenna was 450 mm.
Antenna Coated with HIREC
No deterioration in Carrier To Noise Ratio C/N was shown during and after rainfall.
Antenna without HIREC
Radio reception deteriorated during and after the rainfall.
|The super water repellent paint, HIREC, is an effective countermeasure for rain attenuation in antennas.|
