TX Antenna Configurations
Table 2-19, show configurations for a fully populated SC 4812T–MC
frame with 4X4 ETM. For a SC 4812T–MC frame populated with a 3X3
ETM the lower right quadrant will not be populated.
Table 2-19, also displays the I/O plate for 3 to 6 Transmit Antenna
Connectors (depending on configuration) and
2 to 3 Transmit Antenna
Filler plates (depending on configuration).
