Tech Info / HIREC® Is An Effective Countermeasure Of Rain Attenuation For Satellite Antennas
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. |
