Height: Placing communication dishes and antennae at a higher elevation allows them to transmit signals over a greater distance. This is because the higher the antenna, the less likely it is to be obstructed by buildings, trees, or other obstacles.
Line-of-sight: For optimal communication, it's important to have a clear line-of-sight between the transmitting and receiving antennas. Placing the antennae on high structures helps to ensure that there are no obstructions in the path of the signal.
Coverage area: By placing communication dishes and antennae at a higher altitude, they can cover a wider geographical area. This is especially important for providing communication services to rural or remote areas that may be far from the nearest population center.
Signal strength: The higher the antenna, the stronger the signal strength. This is because the signal dissipates over distance, so having the antenna closer to the intended receivers helps to ensure that they receive a strong and reliable signal.
Reduced interference: Placing communication dishes and antennae on high towers or buildings helps to reduce interference from other sources, such as other radio signals or electrical noise. This is because the higher the antenna, the less likely it is to pick up interference from nearby sources.
In addition to these technical reasons, placing communication dishes and antennae on high towers or buildings can also be beneficial for security purposes, as it makes them less accessible to unauthorized individuals.
