Consider a sector configured with 2 LTE cells operate at 700MHz and 2100MHz,A radio planner tries to align coverage of both cells (consider both are radiating with the same DL Transmission power/same antenna), which of the below tilting values that radio planner may consider to align both cells
L900 = 0o and L2100 = 0o
L900 = 6o and L2100 = 4o
L900 = 4o and L2100 = 6o
