NOTES:
1. Received signal measurements take this loss into account, but the
transmitter output power setting cannot. Set the transmitter output
power higher by this amount.
2. With Mars, MTI, or Maxrad antenna.
3. Antenna gain minus cable loss.
Integrated patch antenna and reflector gains are provided in Table 59.

The calculation of transmitter output power is as follows:
Transmitter output power is settable as dBm on the Radio tab of the module. Example cases of
transmitter output power settings are shown in Table 60.
