Satellite TV has become more common as the size of the dish has become smaller. While it has many advantages, some potential customers may find it not worth the cost. The TV signal comes from satellites in orbit and can give a multitude of channels over conventional TV options, but not everyone can receive it. Before purchasing satellite TV, consider both its advantages and disadvantages.
Subscription service for satellite TV costs between £19 and £58 a month as of 2011, depending on the packages you choose. This cost remains the same for other service providers with one important difference: Satellite line-up packages have a better selection, giving more for the buck. Installation only takes a few hours, but most customers must pay for a professional to install it. Better program packages may offset this cost in the long run, however.
Satellite TV offers far superior picture and sound quality to those offered by cable because it lacks signal dropoff. The signal occurs via a direct high-powered transmission from the satellite to your TV. Many satellites signals come in high-definition digital transmission as a standard. If a clear line of sight does not exist from the dish to the satellite, however, the signal strength will drop and you could lose channels.
You must have the lined up perfectly with the satellite without any obstructions such as trees or buildings in the way. It will also require you to mount it on an extremely strong and solid base to ensure wind does not move the dish. Though the mounting process takes a bit of work to achieve, you'll find it worthwhile in the end when you can have continued uninterrupted reception.
The largest disadvantage to satellite reception lies in dish placement. It must face south, which is not possible for many apartment dwellers, as well as many areas in each city. Many landlords will not allow tenants to install satellite dishes on the premises, making satellite service impossible, and you may need to consider dish placement when moving into a new home.
