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. Differences in
performance figures may result from:
▪ Incorrect alignment of antennas (see “Antenna Alignment” on page 30).
▪ Polarization mismatch of the antennas.
▪ Sources of interference or unexpected reflections in the signal path that affect the communications
quality (see “Antenna Placement” on page 12).
▪ Severe weather conditions such as heavy rain or snow fall, or strong winds.
▪ Seasonal influences such as leaves on trees, or icing on the antennas.
Cable Factor
Determine the Cable Factor from the following table to calculate the probable range for your installation.
Table 1. Cable Factor
