With the Plastic horn antenna, the reference plane is the contact
surface on the side of the focusing lens. With the version with adapter
flange, the reference plane is the lower side of the flange.
Information:
If the medium reaches the antenna, buildup can form on it and cause
faulty measurements later on.
The emitted radar pulses of VEGAPULS 61 are electromagnetic
waves. The polarisation plane is the direction of the electrical wave
component. Its position is marked on the instrument. Polarisation plane
