The property is not allowed to go up to the roof.

It is assumed that the public base station must obtain the opinions of the local radio authorities, and after on-site investigation, formulate the planning scheme for installing antennas.

Then you need to get the consent of more than two thirds of all the residents in your building! This is necessary, because the roof is a public area, and you can only install it if most people ask you to.

The above two procedures are complete, contact the property department. Because the roof has waterproof and lightning protection devices, attention should be paid not to destroy the waterproof layer when installing the antenna to avoid lightning strike. 4-meter-high wires should also be windproof.
