Transmission line monopoles are rapidly gaining popularity over towers as securing new Right-of-Way permits for overhead DC/AC transmission lines is becoming difficult, and in some jurisdictions, impossible due to space constraints.
Monopoles are a viable alternative as they require only one-sixteenth of the space sought by lattice towers for erection while being capable of attaining heights higher than 50m. Additionally, Monopoles have other distinct advantages over towers such as faster installation and shorter delivery times.
