The tower is a steel monopole that comes in two types: one with a hub height of 65m and one of 78m. The 65-meter type is divided into three sections, while the 78-meter type is divided into four.

The equipment is designed to satisfy a wind velocity class of IIA+, the strength to withstand strong typhoons, and economic efficiency in regions of low wind velocity. Moreover, an intra-tower service lift can be provided optionally.
This makes maintenance more efficient.
