W ith the Plastic horn antenna, the reference plane is the contact
surface on the side of the focusing lens. With the version with adapter
fl
ange, the reference plane is the lower side of the flange.
Information:
I
f the medium reaches the antenna, buildup can form on it and cause
faulty measurements later on.
T
he emitted radar pulses of VEGAPULS 61 are electromagnetic
