Tsunami MP.11 Antenna Installation
Procedure
1.Start with the transmit power and the number of the channel to be used. From the output power tables on page 30 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).
3.Add the dBi of the antenna you will be using. The total is the EIRP (equivalent isotropically radiated power).
4.Determine your link budget from the Distance and Path Loss table, For example, if the distance between the two radios is approximately 5 km, the link budget would be 121. (Note that this is the value for 4.8 km, which is closest to the actual value.)
5.Add the gain of the antenna on the second side of the link.
6.Subtract the total loss of all transmission elements between the antenna and the radio on the second side of the link. The result is the Received Signal Level (RSL).
7.From the Receiver Sensitivity tables in the Tsunami MP.11 Installation and Management manual Technical Specifications, find the dBm value for the data rate used for the link.
8.Subtract this value from the Received Signal Level; this is the Fade Margin.
