SET RF POWER LEVELS
RF Power levels will differ depending on the antenna in use and site specifications such as latitude,
antenna orientation, power loss due to length of cable and connectors, and terrain features which
may inhibit a clear view of the satellite (for example: dense foliage). Power levels should be in
accordance with data collection platform radio set (DCPRS) and the Effective Isotropic Radiated
Power (EIRP) for NOAA
or EUMETSAT
.
You must ensure that the DCPRS antenna transmit gain, when combined with the data collection
platform’s output power, does not exceed the maximum EIRP.

Table 3: Maximum effective isotropic radiated power
Refer to your antenna’s specifications and operating manual to determine its gain and determine
the required power output. Note that the transmitter maximum power output (38 dBm).
Once you have determined your required power level range, check the current power level settings
and determine if they need to be changed.
