Radio wave attenuation is caused by snow accreting on the antenna surface and the water film that forms when the snow melts. Therefore, even if the snow is melted with a snow melting heater, if a water film remains, radio wave attenuation will occur.
When painted with HIREC100, snow does not accumulate due to its Super hydrophobic properties and no water film forms, ensuring stable reception.
Table 1 Comparison of radio wave attenuation by antenna countermeasure
measures | Untreated | snow melting heater | HIREC100 | HIREC100 + snow melting heater |
---|---|---|---|---|
radio wave attenuation | Yes | Yes | almost none | almost none |
