2.4 Precautions
Note: Detached antennas, whether installed indoors or out, should be installed
ONLY by experienced antenna installation professionals who are familiar with
local building and safety codes and, wherever applicable, are licensed by the
appropriate government regulatory authorities.
Failure to do so may void the BreezeNET Product Warranty and may expose
the end user to legal and financial liabilities. BreezeCOM and its resellers or
distributors are not liable for injury, damage or violation of government
regulations associated with the installation of detached antennas.
2.4.1 Transmit Antenna
Regulations regarding maximum antenna gains vary from country to country. It is
the responsibility of the end user to operate within the limits of these regulations
and to ensure that the professional installer is aware of these regulations, as well.
The FCC in the United States and ETSI in Europe limit effective transit power to
36dBm (USA) and 20dBm (Europe). The maximum total assembly gain of
antennas and cables in this case equals 19dBi (USA) and 3dBi (Europe).
2.4.2 Lightning Protection
Lightning protection is designed to protect people, property and equipment by
providing a path to ground for the lightning’s energy. The lightning arrestor diverts
the strike energy to ground through a deliberate and controlled path instead of
allowing it to choose a random path. Lightning protection for a building is more
forgiving than protection of electronic devices. A building can withstand up to
100,000 volts, but electronic equipment may be damaged by just a few volts.
Lightning protection entails connecting an antenna discharge unit (also called an
arrestor) to each cable as close as possible to the point where it enters the building.
It also entails proper grounding of the arrestors and of the antenna mast (if the
antenna is connected to one).
