Studying different types of antenna towers used in telecommunication network
Antenna towers play an important role in a wireless telecommunication network. They provide the much needed line of sight to antennas and telecom equipment and allow them to establish links with other telecom towers in the area. There are several types of telecom towers used in a telecommunication network.
Different types of Antenna Towers
Some of the telecom towers used in telecommunication network are self support towers, guyed towers, and flange monopoles. Self support towers are further classified into different types depending on their design and number of legs. The different types of self support telecom towers include-
- 4 Legs Square Angular Tower
- 3 Leg Schifflerized Angular Communication Tower
- 3 Legs Tubular Tower
- 3 Legs Angular tower/Tubular tower
- 4 Legs Square Tower
A brief look at the different types of self supporting antenna towers
Self support towers are free standing structures. They are either 3 legged or 4 legged and have angular or tubular components incorporated in their framework design. Each self support tower is designed for a different height which can be in the range of 20m to 120m. The self support tower design is also optimized to handle medium to heavy loads. The load bearing capacity of each tower is different and plays an important role in its applications in a telecommunication network. The self support towers are available in sections and can be easily transported in a standard 20′ ISO container.
Uses of Self Support Towers:
- GSM/CDMA Equipment
- Microwave Network Junctions
- Marine Radars
- Video Surveillance Equipment
- Air Traffic Control Radars
- Wind Turbines
- Forest Fire Monitoring
- Hub Sites
Guyed Antenna Tower
A guyed tower is a slender telecom tower supported by guy wires. It is the most economical telecom tower as less steel is required for its construction. The installation cost of this type of tower is also low as it does not require a huge foundation. One end of the guy wire is attached to the tower while the other end is fixed to the ground. Generally, a guyed tower has 3 guy wires attached; each guy wire is 120° apart. The guy wires keep the antenna tower erect and firm in its place.
Uses for Guyed Towers
- GSM/CDMA Equipment
- Wind Turbines
- TV
- FM Radio
- Meteorological Equipment
- Video Surveillance Equipment
Flange Monopole
Flange monopole towers have tapered hollow steel sections bolted together with circular flanges. These types of towers are suitable for heights up to 60m. The tower design is specifically optimized to handle medium to heavy loads. The flange monopole tower is available in sections that can be transported in an OT 40′ ISO container.
Antenna towers can be fitted with different types of telecom equipment and accessories that include antenna mounts, obstruction lights, safety devices, antenna mounts, lightning protection kits, and several other accessories. All the accessories and equipment can be fitted on the antenna tower at any height and at any orientation to suit the client’s requirement. The design of the antenna tower can be customized as per cellular site requirements by interchanging the modules.
