If you have a background on fixing up things and other manual labour, then you can challenge yourself and try to conduct the TV aerial installation by yourself.
If you are, however, one of those people who are clueless in antenna installation, just hire someone to set up or fix the antenna instead of putting your life at risk.
Yes, a task like that of installing or fixing a television aerial may seem to be trivial to some, but a simple job like that also poses some dangers. Every year, there are reported accidents due to TV aerial installation or maintenance incidents. That is why getting an experienced person to complete the job may be more beneficial for you.
Would TV aerial installation take a long time? Generally, no it will not be because it only takes one to two hours of working time to finish the set up. The duration of the work to be done depends on the size of the building, the accessibility, the height of the building, the safety equipment available and other safety precautions that must be applied.
If the antenna must be installed on higher areas, professionals may charge an additional fee. That is understandable. Fitting an antenna on top of a three-storey building is a quite a job.
If you are not careful, one wrong slip can cost you your life. This is where aerial installers come in. Experienced engineers or technicians are the right people for the job. They may even have to work in pairs just to manage an installation job on top of high-rise buildings.
Try to measure your knowledge in TV aerial installation. If you do not have the skill to assemble the antenna or the capability to work on height if required, it is better to call up professionals who could make it easier and the best for you.
