Transmitting to the satellite is done on 2m with a more traditional antenna. 2 meter Antenna frequency = 6 GHz Output Gain (dBi) = 47. The higher frequency bands typically give access to wider bandwidths, but are also more susceptible to signal degradation due to ‘rain fade’ (the absorption of radio signals by atmospheric rain, snow or ice). The FCC Rules say that any mode (FM, AM, SSB, CW, etc. All BGAN terminals use the L-Band frequency, which is the same frequency used by satellite phones. A satellite operating in "mode U/V" means the satellite uplink is in the 70 cm band and the downlink is in the 2 meter band.
