Cleaning of the antenna The antenna can get contaminated, depending on the application. The emission and reception of
microwaves can thus eventually be hindered. The degree of contamination leading to an error
depends on the medium and the reflectivity, mainly determined by the dielectric constant
ε
r. If the
medium tends to cause contamination and deposits, cleaning on a regular basis is recommended.
Care has to be taken not to damage the antenna in the process of a mechanical or hose-down
cleaning. The material compatibility has to be considered if cleaning agents are used! The maximum
permitted temperature at the flange should not be exceeded
Electromagnetic compatibility
