Antennas
Proper mounting and placement of antenna(s) is vitally important in wireless systems.
If overlooked, antennas might cause unnecessary problems. In all cases, a clear and
unobstructed line-of-sight path between the transmitting antenna and the receiver(s) is
required.
The antenna might be concealed behind fabric, thin plastic, acoustic tile, and thin
plywood without significantly affecting performance. However, close proximity to
metallic objects such as furniture, lighting fixtures, scaffolding, electrical cables,
metal structural members, aluminum window frames, and equipment cabinets must
be avoided. Whip and dipole antennas require at least a 5-inch (0.1-m) minimum
spacing from metal surfaces. Other types of antennas may require greater spacing.
The manufacturer's recommendations should be followed when using yagis and
other types of specialized antennas.
