There are many options when it comes to aerial installation. First of all, you will need to decide the type of aerial that you specifically require for your particular application. Some aerials can capture signals over a greater area, while others are designed for more local signals. Understanding the differences can assist in choosing the correct aerial installation for your needs.
One standard aerial commonly used is the Yagi aerial. This is a standard TV aerial which is mounted on a pole which is made up of a rod and a reflector. The cable which connects to the element which is near the reflector is known as the “driver”. These types of aerials are best used to receive signals from a transmitter in the direction that the rod is pointed at. The main drawback to this type of aerial installation is that it will receive some, but not all transmission frequencies.
Areas with poor quality digital reception employ an aerial called the Digital High Gain aerial. A couple of reflectors at the rear are required for this aerial installation. They also might require up to 100 elements. This particular aerial is a good option for areas where there is poor reception, although it can be quite costly.
Loft Mounted aerials are the best type of aerial for analogue signals but are not really recommended for receiving Freeview signals. Sometimes the roof tiles or plumbing affect the signal quality. The loss of signal is generally regained by using a satellite grade cable to connect your box to the aerial.
It is crucial to choose the correct aerial when you have aerial installation done for you. Most aerial installers already know a lot about this and will advise you which is best. Although certain aerials work well in some areas, others will not. This is something you need to think about with respect to your aerial installation.
