A man_made=mast is usually a small tower of only a few meters height. It is often built from concrete or steel and only for a single application like a mobile phone base station. A tower is accessible and provides platforms, whereas a mast only offers ladder steps to climb it. You can also find masts next to motorways or railways. High masts may be fastened to ground with guy wires.
Guys can be fixed with insulators to the mast and devided by insulators, if the mast is insulated to ground.
Often masts are built to hold antennas. You could tag a mobile phone base station like this: Proposed_features/Telecommunications_tower
How to map
In structural engineering, mast is a vertical structure, supported by external guys and anchors.
This is the only existing definite feature that could be used to differentiate masts and towers.
