Installation Manual

Tsunami MP.11a Antenna Installation Guide
▪ The location is as close as possible to the point where the antenna cable will enter the building (see
“Placement of the Surge Arrestor” below).
▪ The ideal location has a temperature of 0-55 degrees Celsius and a maximum relative humidity (non-
condensing) of 95%.
CAUTION! The Tsunami MP.11a hardware, the surge arrestor, and the antenna mast must be
connected to the same grounding system.
Cable System
CAUTION! The Tsunami MP.11a products are designed for indoor installation. At all times the
location of the Tsunami MP.11a radio unit and power supply must be indoors, to protect
the unit from extreme weather conditions, excessive heat and humidity, and to keep the
unit free from vibration and dust. The antenna and surge arrestor can be placed
outdoors.
Prior to mounting the Tsunami MP.11a, you are advised to calculate carefully:
▪ The distance between the intended location of your Tsunami MP.11a hardware and the location of the
antenna mast
▪ The height of the antenna on the mast.
If the low-loss antenna cable is not long enough to cover this distance you can select another:
▪ Cable length from the Proxim Systems low-loss cable offering
▪ Location that satisfies the requirements listed previously to mount your Tsunami MP.11a hardware
As the length of the antenna cable may affect the actual range of your outdoor antenna installation, the last
option is preferred.
WARNING! You must not change the length of the low-loss antenna cable to a length shorter than
allowed by the radio’s certifications (see “Appendix C. Certified Outdoor Solutions “on
page 47. Shortening the cable will void the Proxim Corporation warranty and may
conflict with radio certifications or approvals.
How to install the Tsunami MP.11a hardware is described in Tsunami MP.11a Installation and Management,
which comes on the Tsunami MP.11a product CD.
Placement of the Surge Arrestor
The surge arrestor is an indispensable part of your outdoor antenna installation. It protects your sensitive
electronic equipment from transients or electro-static discharges at the antenna.
For optimal protection, the surge arrestor must be installed at a location that satisfies the following
requirements:
▪ A location as close to the location where the antenna cable will enter the building (see “Placement of the
Tsunami MP.11a Hardware” on page 9).
▪ The location allows for easy disconnection of the surge arrestor from the cable connected to the unit.
▪ The location provides a connection to the same grounding system as the Tsunami MP.11a hardware and
the outdoor antenna mast (as described in “Grounding System” on page 16).
