Radio input connector on the amplifier (refer to figure 2-5). To power on the TCR-MBA-75 NBT the ON/Off switch on the Bias Tee must be in the On position and then the user must also press the ON/OFF button on the TCR- MBA-75 NBT for approximately 2 seconds. -
Page 15: Out Of Band Operation
Figure 2-5. Remote Operation Setup 2.3.3.4 Out of Band Operation Operating outside of the UHF SATCOM frequency bands with the SATCOM mode selected will cause an alarm to occur. Returning to the receive mode will clear the transmit frequency fault alarm. Operating on SATCOM frequencies while in the LOS mode with an antenna connected to the LOS port will not cause an alarm and it will operate properly, however, the amplifier will not comply with the timing requirements for DAMA operation. -
Page 16: Installation General Information
INSTALLATION General Information This section contains information necessary for preparing the TCR-MBA-75 NBT for use. Preparation for Use After unpacking the system and inspecting for physical damage, select an appropriate location for the Amplifier. Although the Amplifier is weather-resistant, placing it in a location where it is protected from direct salt spray, rain, and sunlight will increase its service life. -
