Removable guyed masts are used not only for telecommunications purposes, but also for collecting wind data in order to evaluate the profitability of a planned wind farm. Such removable and permanent towers can reach heights of up to 492 ft and are mounted at the planned windmill height in uninhabited areas.

The Spanish company Lasser Eólica specializes in evaluating wind data. Their services also include the design, documentation, and construction of guyed masts worldwide. The main goal of the tower structure is to achieve maximum wind permeability. Therefore, the towers consist of tubular steel trusses with a triangular ground plan. For each plane, three sets of prestressed cables are used to stabilize the tower at different heights.

To avoid measurement errors during data collection, measuring devices such as the anemometer and weather vane must be positioned by level arms at a certain distance and a certain height from the tower surface, according to ISO 61400-12-1.
