Tower, We often see big towers in our street but we often think why they look different place to place. Why their structure vary if they do the same task? What is the different type of towers used for what purpose? Let we answer your above questions here.
What is a Tower?
The tower is a tall narrow building like structure, stand in free space to work for a certain task. These are big in size with higher in length and less in breadth. We towers are too big in size because of signal attenuation problems from buildings and also to avoid overlapping of different towers frequencies.
Why towers have a different structure?
Due to their different uses and the reason for mounting different devices on it, the companies build it different from each other. Some are used for transferring electricity, So the structure is like it can handle lots of wires, Some are used for radio transmission for that tower structure is like it can easily mount big transmitter and receivers on it. But one thing is common in all these towers i.e.they are too big from our houses or buildings.
What are the different type of towers?
- Monopole Tower: It looks like a pole and can be used in a variety of communication applications. Its conventional use is Telephony. It has a height between 100 to 200ft. In Monopole tower devices are mounted on the exterior of the tower. These type of towers are preferred in urban areas because of its clean appearance. Monopole also has different categories like Rapid deploy monopole, flagpole, Standard monopole, Mole pipe. It depends on the need of the area which tower is suitable in terms of height and frequency.
- Lattice Tower: This tower is also known as tree tower because it looks like a tree. It is also known as self-support tower. They can be used as electricity transmission towers especially for voltages above 100 kilovolts. Previously they were used for Radio signal transmission. These towers have a height between 200 – 400 ft. The tallest wooden lattice tower was at Mühlacker, Germany. It has a height of 620 ft. Eiffel tower is also an example of lattice Tower.
- Guyed Towers: These towers are in all the ranges of a lightweight to heavyweight. Its structure is like a straight rod supported by Guy wires. These are very efficient and has very good strength. It is the cheapest tower to construct if we want a 300 ft tower. Guyed Towers are typically used in cellular, wireless internet, broadcast, homeland security, television, and other wireless applications. Some Guyed towers can reach at the height of 2000 ft.
- Concealed Tower: Concealed tower are manufactured to satisfy zoning regulations. They named as conceal towers because it hides its identity and can be formed in a way different from the tower structure. These are made to give a range in a small area or surroundings. We can use it at home where we are not getting coverage from a big antenna too. They are expensive than other types of antennas because of their self-use. Municipalities who require the use of for a streamlined zoning review process can save the high costs involved with fighting the carriers in the courts. They require additional material to create a “concealed appearance,” yet at the same time, they provide less capacity to the users as compared to the big tower.
- Broadcast Towers: These are the towers which are made to provide services for FM radio, AM radio, and Television (TV) antennas. These antennas are heavy weighing which is around 1000 pounds to 15 tonnes. The weight depends on the services it provides, and how much area we want to cover. These are mainly used for covering and giving range to huge area i.e in mountains or hill station. This tower can provide range up to 300 acres. Most broadcast towers are guyed towers with three or more guy wires attached to grounded anchors. Rural areas are covered mostly with Broadcast Towers.
