Tsunami MP.11a Antenna Installation Guide
 
Antenna Mounting 
There are two ways to erect an antenna mast:  Tripod Mount and Wall (Side) Mount.
 
Tripod Mount 
The tripod mount is primarily used on peaked and flat roofs. The antenna mast must be secured to the 
roof using 3 or 4 guy wires equally spaced around the mast. When the height of the antenna mast is 
more than 3 meters (10 ft), you are advised to use at least three guy wires for each 3 meters (10 ft) 
section of the mast. 
Wall (Side) Mount 
A wall (side) mount allows for mounting an antenna (mast) on the side of a building or on the side of an 
elevator penthouse. This will provide a convenient mounting location when the roof overhang is not 
excessive 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 let you align the antenna properly with 
the corresponding antenna at the opposite end of your wireless link. As poor alignment typically results in 
poor performance, Proxim recommends always mounting the antennas to a mast.   An exception to this 
rule is the wide-angle window antenna that can be mounted on a window or wall facing the nearest Base 
Station with line of sight.

Requirements
 
To accommodate the antennas, the antenna mast must satisfy the following requirements: 
▪ 
The construction of the mast must consist of sturdy, weatherproof, and non-corrosive material such as, 
for example, galvanized or stainless steel construction pipe. 
▪ 
Typical diameter of the mast should be between 35 mm (1.4 in) and 41 mm (1.6 in). Depending upon the 
type of antenna you intend to install, other diameters also may be possible. 
▪ 
The height of the antenna mast must be sufficient to allow the antenna to be installed at least 1.5 m (5 ft) 
above the peak of the roof.  If the roof is of metal, the height of the antenna should be at least 3 m (10 ft) 
above the roof. 
▪ 
The mast or wall bracket must be free from any substance that may prevent a good electrical connection 
with the antenna such as, for example, paint.
