Our customer builds and operates a wide range of monitoring equipment such as radio antennas that are required to operate reliably even in adverse weather conditions. To do so, the antennas are heated and include a fan to prevent the accumulation of snow on the surface of the antenna. During heavy snowfall however, it was repeatedly observed that the fan was not able to remove the snow which caused the signal quality to deteriorate.
Our task was to optimize the snow removal efficiency without changing the instrument too much. The solution should also be applicable to already installed systems.
