Figure 2.2: False handling of the antenna
Because of the functional principle it must be taken care that the antenna is not inductively short-circuited
by the mounting construction. Especially the direct mounting on a frame or a plate of metal provoke such a
short-circuit and can lead to a destruction of the antenna. When mounting on a concrete wall it is to notice
that this wall may contain reinforcing iron in an unfavourable geometry. In this case only a power dissipa-
tion occurs because of the distance of the iron-structure, but not a complete short-circuit. In this configura-
tion the reading range is lower than specified and the current consumption is higher than normal.
When operating an antenna in laboratory it must be paid attention that the antenna in operation must not
be laid on another antenna. In such a case also an inductively short-circuit takes place which may lead to a
destruction of the antenna.
Two adjacent antennas should have a distance of at least 50 cm to each other.
