Tsunami MP.11 Antenna Installation
Mounting the Antenna
As the mounting procedures for the various antennas differ from one another, consult the documentation
you received from the manufacturer for mounting procedures.
Proxim Wireless Corporation offers multiple antennas to set up a wireless link (as well as a unit with an integrated antenna).
When mounting multiple antennas on a single mast, use the following methods to minimize the influence of cross- talk interference between the antennas:
•Place your antennas as far apart as possible
•Alternate the mounting of directional antennas for vertical and horizontal polarization
There are two frequently used methods to erect an antenna mast:
Tripod Mount
The tripod mount is used primarily on peaked and flat roofs. The antenna mast must be secured to the roof using three or four guy wires equally spaced around the mast. When the height of the antenna mast is more than 3 meters (10 ft), you should use at least three guy wires for each
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 provides a convenient mounting location when the roof overhang is not excessive or when the location is high enough to provide a clear
In most situations mounting an antenna directly to the wall does 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.
Antenna Mast Requirements
To accommodate the antennas, the antenna mast must satisfy the following requirements:
•The construction of the mast must consist of sturdy, weatherproof, and
•Typical diameter of the mast should be between 35 mm (1.4 in) and 41 mm (1.6 in) (up to 4 in for
•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 (for example, paint).
