Choosing the Right Antenna Distance Chart Link Gain *Unobstructed
Link Gain is a composite of the gains of each of the antennas (the Master’s antenna and the The chart to the right has been adjusted to (dB) Distance
Remote’s antenna) as well as any cable loss. For example, if you want to communicate over a allow for 10dB of “margin” in your system. 35 15 mi (24.2 km)
2 mile (3.2km) unobstructed distance, you should include at least 7dB of Link Gain. This margin accounts for expected changes in 30 12 mi (19.4 km)
Master antenna gain: 8 dBi (Omni-directional xxx-xxxx) the environment during operation. 25 10 mi (16.1 km)
Remote antenna gain: 8 dBi ( ----- ) 15 5 mi (8.0 km)
Cable at the Master: -2 dBi (4 feet or ) 7 2 mi (3.2 km)
Cable at the Slave: -5 dBi (10 feet) 4 1 mi (1.6 km)
Total Link Gain: 9 dBi * Radio power set to Max.
More gain will give you more distance. It doesn’t make any difference whether the gain is on
the Master or the Remote radio. The gains of the two antennas is additive.

Make the choice for each antenna pair (if you have a point-multipoint system).
