With the development of telecommunication technology, EBJ take chances and play a role in the field of telecommunications construction services in infrastructure and Fiber Optic project. Since 2003 EBJ has installed thousand miles of Fiber Optic for all operator in this country. Since 2002 EBJ was participate to build Telecommunication Tower in all region in Java, Sumatra, Borneo, Sulawesi and also Moluccas. Until present we had build 400 towers in Indonesia. Tower BTS (Base Transceiver System) as a means of communication and informatics, in contrast to the tower SUTET (Extra HighVoltage Air Line) PLN in terms of construction, as well as the risk borne by the people under him. BTS tower communications and informatics have a high degree of safety to humans and the creatures living under it, because it has a very small radiation so it is safe for people under and around it.

Macro Tower

4 Legged Self Supporting Tower

This Four-legged tower is very rarely found collapsed, because it has the power of piles and construction are considered. Tower is able to accommodate antenna and radio a lot. Maximum tower height of this type which is recommended is 72 meters. This tower type is widely used by business firms are bonafide communications and informatics. (Indosat, Telkomsel, Xl, etc).

3 Legged Self Supporting Tower

This Three-legged tower has the ability to carry moderate to heavy accessory loads. Built with tubular legs without the use of supporting cables, this tubular design features improved strength-per-pound ratio. Maximum tower height of this type which is recommended is 72 meters. Engineered to meet your height requirements, this tower is appropriate for nearly all communication applications.

Pole Tower

Pole tower is a kind of tower that consists of one stem or one pole anchored to the ground. This tower is usually lower than the tower transmitter type of self supporting tower and designed to derives the lighter load from the kind of transmitter tower self supporting, so this tower will not be able to derives heavy load as the antenna which have dimension and heavy large.

Guy Mast Tower

Guy Mast tower is a tall thin vertical structure that depends on guy lines for stability. This tower has the compressive strength to support its own weight, but does not have the shear strenght to stand unsupported and requires guy lines. Guy lines are diagonal tensioned cables attached to the ground, usually spaced at equal angles about the structure’s base, to resist lateral forces such as wind loads and keep it upright.

Micro Tower

Micro Cell Pole Tower aflkasfnaskfnasl

Since less land space is required for micro cell pole sites, they are generally less capital intensive and require less time to construct compared to macro cell sites, although due to the more extensive insfrastructure provided to tenants at micro cell pole sites, lease fees for micro cell pole are generally higher than lease fees for macro cell sites. EBJ has Micro Cell Pole Tower in all region in Java and Sulawesi.
