When looking out for tv aerial installation for your home, you have to consider the company or installers’ experience in the job.
You should hire a TV aerial installer who is quick to service, inexpensive and one that will do a very clean job and wiring.
Also consider other facts as some property owners may not like the appearances of a TV aerial system mounted on their house or condos. Also - some property owner's association disapproves of such appearances. In such case, your best option is probably an attic TV antenna followed by an indoor TV antenna.
Technically and generally, the Telecommunications Act permits you to install an outdoor TV aerial within reason. As far as you are not obstructing on safety or historic conservation and your TV aerial mast is not above twelve feet of your home’s roofline and you are on your property, you are rightfully permitted to install an outdoor TV aerial for free TV antenna reception.
When installing a TV aerial, consider also that the higher the antenna is off of the ground, the better for reception. This is so since it provides you lesser chances of receiving degraded TV signals which bounces off of walls. The higher the aerial, the more direct the signal reaches you.
