    Telescopic RDS Towers

    1. Products

    Rapid Deployment telescopic tower

    allowing easy and fast erection in narrow sites, without any need of foundation and civil works. Their use is strategic for the rapid expansion of cellular networks, putting into service point to point radio links. The base frame is composed of steel galvanized beams and precast concrete slabs. It is designed to place a shelter of up to 3 m and it is equipped with open type grillage flooring and surrounded by grating fencing. The installation can be completed in one working day, since no foundation and civil works are requested.


    2. Standard

    Rapid Deployment Tower could be fabricated as per GB, EN or ASTM standard with high quality.
