Mounting
An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the
antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF
signals from the air.
Choosing the right antennas and positioning them properly increases the range and coverage area of a
wireless LAN.
A wall (side) mount allows for mounting an antenna (mast) on the side of a building or on the side of an
elevated penthouse. This will provide a convenient mounting location when the roof overhang is not
excessive and/or the location is high enough to provide a clear line of sight.
In most situations mounting an antenna directly to the wall will not allow you to properly align the antenna
with the corresponding antenna at the opposite end of your wireless link. As poor alignment will typically
result in poor performance, we advise you to always mount the Outdoor Wireless Bridge to a mast.
Antenna Mast/Antenna Requirements
To accommodate the ZyAIR, the mast must satisfy the following requirements:
The construction of the mast must be of a sturdy, weatherproof and non-corrosive material, for
example, galvanized or stainless steel construction pipe.
Typical diameter of the mast should be between 35 mm (1.4") and 41 mm (1.625"). Subject to the
type of mast that you intend to install, other diameters are possible.
The height of the antenna mast must be sufficient to allow the antenna to be installed at least 1.5 m
(5') above the peak of roof. If the roof is metal, then the height of the antenna should be a
minimum of 3m (10') above the roof.
The mast or wall-bracket must be free from any substance that may prevent a good electrical
connection with the antenna, for example, paint.
