5.4.1 General
The antenna is the component in your system that maintains the radio link
between the network and the modem. Since the antenna transmits and
receives electromagnetic energy, its efficient function will depend on:
the type of antenna (for example, circular or directional);
the placement of the antenna;
communication disturbances in the vicinity in which the antenna
operates.
