Aerials – Installation Tips

Spread the love

Installing TV antennas is no easy task: there are many different things you should account for, from the type of antenna you use to the mount and location where you will position your antenna. Each of these decisions can affect the overall quality you will get out your antenna, so it is important to be careful. Here are some helpful tips to consider:

Indoor vs Outdoor

Antennas come in largely two varieties: the type that can be installed within a building, and the type that is installed outdoors. Of the two, indoors antennas tend to be cheaper and work well as long as you live close enough to the transmission towers in your area. This is why you should always make sure to research beforehand whether there is a tower in the vicinity of your household – you can easily save up on TV antenna installation costs as indoors antennas are both cheaper and easier to install. Conversely, you can always order an indoors antenna first and test it out – it might work fine, and if so, you can keep it. If you cannot pick up a decent signal this way, you can always return the antenna and order an outdoors antenna instead.

Elevation

The most common advice you hear when it comes digital antenna installation Sydney is to place the antenna at the highest possible location in your home. The reason for this is because the highest elevation often tends to have the least amount of obstruction. When it comes to digital broadcast signals nowadays, you should know that they are transmitted in two different ranges: UHF and VHF. The former, UHF, is at a higher frequency and are very susceptible to obstruction due to walls, trees and the like. VHF, the latter, is of a lower frequency and much less prone to obstruction (but thick walls can still weaken it nonetheless). You want to have a higher elevation to capture the UHF signals mainly, but also to ensure the best possible quality for the VHF signals as well.

Keep in mind that the highest elevation – and even outdoors – might sometimes not do much for you. This is often the case with geographical obstacles, such as hills and valleys. People who live close to hills or other higher-terrain, and who find out that their transmission tower is located in a way that the antenna has to capture signals through the hill or the elevated terrain will often have to give up on OTA content for their television, as the obstruction tends to be too great for the antenna to work properly.

Preamplifiers

Lastly, another good point to consider during the installation of an antenna is the total length of your cable. If you did not know, cable length can significantly affect the overall quality of an antenna connection. In other words, the longer is the cable connecting the television to the antenna, the poorer the overall reception quality will be. That being said, certain households cannot find a way to shorten the cable enough to circumvent this issue. In these situations, you can buy a preamplifier, which can strengthen the signals captured by the antenna and improve the reception quality.
