Question
1). Which of the following are areas of key concern when installing antennas? Choose all that apply. a). Placement b). Mounting c). Environment that it is used in d). Orientation and alignment e). Safety f). Maintenance considerations 2). Antenna polarization refers to the alignment or orientation of the waves. Polarization is more important indoors than outdoors. a). True b). False 3). List the following information concerning a sector antenna. a). How does it differ from other types of semidirectional antennas? b). What is the range vertical beamwidth? c). What is the range of horizontal beamwidth d). What is the typical gain in dBi
Explanation / Answer
1- a, b, c, d and e.
Placement is impirtant as it decides where to want to place the antenna. Sometimes it is necessary to install the antenna at the centre of the coverage area and sometimes not.
After the place is decided, the mounting is also important. Its access point can be hidden or not. Many more factors regarding the mounting are considered.
Environment should should also be taken in account. Indoor and outdoor types of antennas are present. They should be installed according to the environment they are to be used in.
Orientation and allignment is also necessary.
Safety is also very important while installing antenna.
Maintenance should be easy. Hence antenna is installed accordingly.
2- False
As the antenna polarization more important outside . The polarization should be same on both sides.
3-
a-
sectoror anetenna uses angles to cover some area. It covers the area for specific angles.
Directional antennas dont use angles. They just uses direction.
Hence sector antenna is more specific.
b-The vertical beamwidth of a sector antenna typically range from 10 to 15 degree.
c- The horizontal beamwidth of a sector antenna typically range from 65 to 90 degree.
d- typical gain is 14 to 20 dbi.
