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 (noncondensing) 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.
Tsunami MP.11a Antenna Installation Guide Antenna Cable Route The antenna cable must be connected from the antenna through the surge arrestor to the pigtail connector of the MP.11a unit.
Tsunami MP.11a Antenna Installation Guide OVERVIEW OF THE OUTDOOR INSTALLATION The outdoor installation of the link (point-to-point or point-to-multipoint) requires the following: ▪ ▪ ▪ ▪ ▪ An antenna A low-loss antenna cable (available in three lengths) Antenna mast or wall bracket for the antenna An adequate grounding system that meets the requirements described in “Grounding System.
Tsunami MP.11a Antenna Installation Guide The following figure shows some typical examples of obstacles that you must avoid for the directional antenna to operate effectively: ▪ ▪ ▪ Neighboring buildings Trees or other obstructions Power lines To allow optimal performance you must ensure that the type and placement of the antennas leave sufficient clearance of the Fresnel Zone at the maximum width of the bulge, which is typically at the mid-point between the antennas. Figure 4.
Tsunami MP.11a Antenna Installation Guide Environments with large reflective surfaces include: ▪ ▪ ▪ ▪ Mirror-glass buildings Crowded parking lots Water or moist earth and moist vegetation Above ground power and telephone lines Note: The use of reflective surfaces can be used to improve a link, especially if the direct line-of-sight is impaired or absent. Weather conditions such as rain or snow usually do not have much impact on the performance of your Tsunami MP.
Tsunami MP.11a Antenna Installation Guide 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 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.
Tsunami MP.11a Antenna Installation Guide Chapter 2. Determining Range and Clearance When you read about wireless outdoor products, you often encounter the terms output power of the radio and gain of the antenna equipment as measures for the strength of the transmitted signal. ▪ Output power of radio equipment often depends on maximum limits as defined by local radio regulations; consequently, output power is, by definition, not the way to enhance wireless performance.
Tsunami MP.11a Antenna Installation Guide Maximum Range The maximum range of your Tsunami MP.11a system is based upon: ▪ ▪ ▪ The Type of Outdoor Antenna Equipment The Data Speed of the Wireless Link The clearance of the signal path (see “Clearance Factor” on page 18). The values in this section are based on calculations that assume optimal radio conditions. They do not represent a guarantee that the same maximum distance can be achieved at your location.
Tsunami MP.11a Antenna Installation Guide Clearance Factor For optimal performance of your outdoor wireless link, the signal path between the Base Station Unit and Subscriber Unit must provide sufficient clearance. Note: A outdoor wireless link that lacks sufficient clearance will suffer from poor performance, which is typically perceived as slow network response times. Although your Tsunami MP.
Tsunami MP.11a Antenna Installation Guide Clearance should be interpreted as follows: ▪ In open areas without obstacles in the signal path, clearance is measured as height above the surface of the earth. For example, if the antenna is mounted on the roof, this height includes the height of the building plus the height of the mast above the rooftop. ▪ In areas with obstacles in the signal path between the two antennas, clearance should be measured as height above the highest obstacle in the signal path.
Tsunami MP.11a Antenna Installation Guide CALCULATIONS Availability of the microwave path is a prediction of the percent of time that the link operates without producing an excessive bit error rate (BER) due to multipath fading.
Tsunami MP.11a Antenna Installation Guide Procedure: 1. Start with the transmit power and the number of the channel to be used. From the output power tables (on page 23) find the dBm associated with this output power and channel. 2. Subtract the total loss of all transmission elements between the antenna and the radio on one side of the link (dB). (See “Minimum Antenna Cable Loss in 5 GHz Bands” on page 24.) 3. Add the dBi of the antenna you will be using.
Tsunami MP.11a Antenna Installation Guide Notes: ▪ The RSL must be higher than the Receiver Sensitivity plus the minimum SNR for a good link. See Table 3 on page 23, to have a working link with no excessive errors. The amount of Fade Margin indicates the reliability of the link; the more Fade Margin, the more reliable the link. ▪ The path loss must be smaller than the link budget minus the minimum required fade margin.

Tsunami MP.11a Antenna Installation Guide Chapter 3. Installing the Antenna PLANNING ANTENNA INSTALLATION Plan the day for your outdoor antenna installation carefully. Do not install the antenna in wet or windy conditions, during a thunderstorm, or when the area in which the equipment is to be installed is covered with ice or snow. The grounding system for the antenna mast, Tsunami MP.11a hardware, and surge arrestor should be installed before the cable from the antenna is connected to the surge arrestor.
Tsunami MP.11a Antenna Installation Guide Antennas shall be mounted in such a manner to minimize the potential for human contact during normal operation. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not be less than 20 cm (8 inches) during normal operation. The low-loss antenna cable that will connect the antenna with the surge arrestor must be at least 1 m (3 ft) away from any high voltage or high current cable.
Tsunami MP.11a Antenna Installation Guide MOUNTING THE ANTENNA Proxim Corporation offers multiple antennas to set up a wireless link. As the mounting procedures for the various antennas differ from one another, consult the documentation you received from the antenna manufacturer for mounting procedures. 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 you can.
Tsunami MP.11a Antenna Installation Guide Sealing the Cable Connectors Most problems associated with wireless outdoor installations are related to degrading performance due to corrosion of the antenna cable and cable connectors. To avoid this type of problem, you must always seal the cable connectors that are located outdoors using the weatherproofing tape provided.
Tsunami MP.11a Antenna Installation Guide Antenna Alignment For optimal performance of your wireless link, make sure the antennas are properly aligned (facing one another “eye-to-eye”). To align the antennas: ▪ ▪ Use a pair of binoculars or a map of the area and a compass to point the antennas to one another. ▪ ▪ The Link Test option lets you display the radio signal strength in relation to the noise in the signal path.
Tsunami MP.11a Antenna Installation Guide Appendix A. Outdoor Antenna Equipment As described previously, Proxim Corporation offers different types of outdoor antennas and cable lengths for your network design. The directional antennas provide maximum range, but due to their narrow beamwidth, these antennas require precise antenna alignment to achieve optimal performance. The higher the antenna gain, the more precise the alignment should be.
