Monopoles are actually cheaper based on life-cycle-cost
Advantages of monopole in comparison to conventional tower are: Less right-of-way (RoW), better appearance, less components resulting in faster installation, better reliability under extreme conditions, design flexibility, vandalism proof, reliable performance and longer service life.
Right of Way for Monopoles
There is an emergent need to provide high voltage electric power transmission that minimises impact on the environment, agriculture and communities. Overhead transmission lines have been the normal, located on designated rights-of-way.
