Will this RM551E-GL work when only one only anteena port is connected

hi, i have RM551E-GL, the router has 4 5G anteena connection ports. I have bought a 4x4 MIMO directional anteena. My plan is to install this anteena in the roof and use LR-400 cable to connect all 4 outputs into one and bring it down to and connect to single port of the router. Will this setup work? any other solution?

Dear @safwanAhmadKhan2025
Actually different antenna ports have corresponding feature, please refer to the picture as below.
It is not recommended to use only one port.
