When installing a TV aerial, a lot goes into the task. It would help if you choose the suitable antenna, the right cables, and even the right tools. Worst case scenario is an aerial that needs to be correctly aligned and won’t work. Fortunately, this is only sometimes a complex process. An aerial specialist is the best to advise.
Initially for installation, you’ll need to decide on a mast height that will work best for your situation. High masts provide more signal strength and are less susceptible to building interference.

It’s a good idea if the antenna is high and not too far away from the TV. Sometimes, you may need to replace the antenna with a higher gain model. Also, you should not install the antenna next to any tree branches or electrical wires; magnetic metals can interfere with the signal.
A DVB-T spectrum analyser will give you an idea of the signal’s strength. Using a quality coaxial cable will avoid losing a signal from the television. Choosing an aerial that has a decent polarisation will also help. While an omnidirectional aerial will perform the same function, directional models have a reflector at the back of the mast.
For the best results, you should be able to see at least fifty dB. The maximum signal strength should be 80 dB. There are ways to improve the strength of the signal, but that is only sometimes possible.
If you’re considering purchasing a new TV to tune in to local digital channels, an interior flat antenna can also boost your signal. You should ensure the coax cable is short enough during the installation process, and this is especially important if you are installing multiple televisions.
You can also purchase a TV signal strength meter. A meter will give you a rough idea of where your antenna should ideally be placed and the signal strength. Using a meter will also show you whether your aerial is appropriately aligned. A signal meter will also allow you to see if you need to add a cable or a new antenna.
