Tower location
There are a number of things you should keep in mind when choosing the physical location of the tower/mast. Of course, you must ensure that there is the necessary free space on the ground where the tower is placed. Check the specifications of the tower/mast you plan to buy to understand the size of the floor area.
The ideal location for the tower/mast is a flat, level field. However, any reasonable horizontal space can be used, and there is enough space for the foundation. The site should be free of obstacles such as trees and buildings. Not only the location of the tower needs to be cleaned up, but the surrounding area also needs to be cleaned up, because some free space is needed when assembling the tower.
Don't forget that the tree has roots. Digging holes in the huge root system is not a dream.
Medium and high towers/masts usually require a lot of excavation, because concrete foundations must be placed. An underground utility inspection is always required to ensure that there is no infrastructure in the area you plan for the tower/mast.
Also, if the tower is tall, if you need to apply for a permit and/or register the tower with any authority, be sure to consult the country's regulatory agency. If the site is close to the airport, special regulations need to be followed.
