Cleaning 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
εr. 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
