Four Types of Communication Towers

Image
  With the growing popularity of mobile phones over the last 15 years, you can now find communication towers almost everywhere. However, it is important to note that not all mobile phone towers are the same. There are four different types of  communication towers  that can be used to transmit cellular signals. Different types of mobile phone towers can be installed for specific purposes.   Guyed Tower A guyed tower is a light- to heavy-weight communication tower constructed with straight rods aligned in a triangular form, but supported with wires at all angles.   Guyed towers are especially tall, reaching heights as high as 2,000 feet, and are typically used to hold antennas high off the ground allowing for greater signal strength and cell reception.   In addition to cellular use, they can also serve for radio and television purposes. They are ideal for rural customers who require maximum height at an economical cost.   Monopole Towers A single tubular...
