1. The tower sections can be guyed, but can also be used in Bracketed and self-supporting applications

2. A cage aerial is mounted on a 215 m-high guyed, earthed steel-lattice mast.

3. In the year 2000 a 120 metre high, guyed, grounded mast of lattice steel carrying a cage aerial for medium wave was built.

4. An expression for estimating the effective length factors for solid round steel leg members of all-welded guyed lattice towers with cross-bracing is developed.
