maximum total assembly gain of antennas and cables in this case equals
19dBi (USA) and 3dBi (Europe).
Violation of government regulations exposes the end user to legal and
financial liabilities. BreezeCOM and its resellers and distributors shall not
be liable for expense or damage incurred as a result of installations which
exceed local transmit gain limitations.
5.5.3. Spurious Radio Frequency Emissions
The regulations referred to in the previous section also specify maximum
“out-of-band” radio frequency emissions. Install a filter as close as possible
to the BreezeNET PRO.11 “D” model unit connector.
5.5.4. 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).
The lightning arrestor should be installed and grounded at the point where
the cable enters the building. The arrestor is connected to the unit at one end
and to the antenna at the other end.
The professional installer you choose must be knowledgeable about
lightning protection. The installer must install the lightning protector in a
way that maximizes lightning protection. BreezeCOM offers the following
high-quality lightning arrestor assembly:
