Tech Info / HIREC® May Drastically Reduce Life Cycle CO2Emission of Antennas
HIREC®: Super Hydrophobic Coating for Antenna, Radome and Other Public Infrastructure
HIREC® - Environmental Impact Study
Concerns about environmental impacts of infrastructure systems are growing today. The life cycle CO2 emissions were studied for an antenna coated with HIREC® and that with a snow melting heater system. The assessment results show HIREC® may reduce by almost 90% of life cycle CO2 emission of antennas comparing to that of conventional antennas with a snow melting heater system.
Assessment of Environmental Impact Reduction
Antennas set in the snowy area are equipped with a snow melting heater system in order to melt the snow and to prevent deterioration of broadcast reception. Antenna coated with HIREC® prevents the accumulation of the snow and the formation of the water film.
