The agreement "mast" and "tower" are generally acclimated interchangeably. However, in structural engineering terms, a belfry is a independent or cantilevered structure, while a mast is captivated up by stays or guys. Advertisement engineers in the UK use the aforementioned terminology. In US advertisement engineering, a belfry is an antenna anatomy absorbed to the ground, admitting a mast is a vertical antenna abutment army on some added anatomy (which itself may be a tower, a building, or a vehicle). Masts (to use the civilian engineering terminology) tend to be cheaper to body but crave an continued breadth surrounding them to board the guy wires. Building are added frequently acclimated in cities area acreage is in abbreviate supply.
There are a few ambiguous designs that are partly free-standing and partly guyed, alleged additionally guyed towers. For example:
The Gerbrandy belfry consists of a independent belfry with a guyed mast on top.
The few actual Blaw-Knox building do the opposite: they accept a guyed lower area baffled by a freestanding part.
Zendstation Smilde, a alpine belfry with a guyed mast on top (guys go to ground)
Torre de Collserola, a guyed belfry with a guyed mast on top (tower allocation is not free-standing)
