When it comes to watching TV, a reliable signal is crucial for a smooth viewing experience. The quality of this signal depends largely on your TV aerial. However, choosing between an indoor and an outdoor TV aerial can be confusing.
Both indoor and outdoor antennas have their advantages and disadvantages, and the right choice depends on several factors, including location, budget, and installation feasibility. In this guide, we’ll explore the key differences between indoor and outdoor TV aerials, helping you make an informed decision.
2. Understanding Outdoor Antennas
What is a TV Aerial?
A TV aerial (or antenna) is a device that captures broadcast signals from television stations and converts them into signals that your TV can display. Without a proper aerial, your TV may struggle to receive clear signals, leading to pixelated images or frequent disruptions. Understanding the type of antenna you need, from larger outdoor antennas to indoor models will aid in getting the optimum number of channels being broadcast in your region.
How Do TV Aerials Work?
TV aerials work by picking up radio waves transmitted by TV stations. These signals travel through the air and are captured by the aerial’s elements, which then send the signals to the TV via a coaxial cable. The quality of reception depends on factors like distance from the broadcast tower, obstructions, and aerial type. You generally need an antenna to watch free over-the-air television such as Freeview.
