Enlarge the signal in your digital satellite receiver

  If you use an antenna then by now you've probably noticed differences between analog and digital television - a wider screen, channel numbers with decimal points, use of a DTV converter box, and so on. There is another difference, an invisible difference, which is the cause of lost or inconsistent reception and a new Federal Communications Commission (FCC) translator program. It's the digital TV signal.

  Given identical broadcast conditions, a digital TV signal won't travel as far as an analog TV signal because terrestrial constraints affect it more than analog. Things that affect reception include roofs, walls, hills, trees, the wind, etc. A digital signal is so sensitive that a person walking in front of it can knock it offline. In comparison, an analog signal is like a roach. It'll take more than someone walking in front of the antenna to drop the signal.

  Moral of the story is that in order to receive a good over-the-air picture you need a good signal entering the TV tuner, whether it's located within the TV or digital converter box. The problem is that signal loss is a concern with digital TV.

  In some circumstances, you can do everything right and still not get a signal. Or, you may experience too much signal loss while the digital TV signal travels from the antenna to the tuner. Whatever the case, amplifying or boosting the signal is a potential fix to your reception issue.

  The key criteria for amplification are that you have an existing signal being received by the antenna. If the antenna has a signal then enlargement could be a cure for intermittent signal loss.

  In this example the nozzle is the amplifier and water is the digital TV signal. The amplifier uses electricity to harness the TV signal and send it on its way with an electrical boost. This allows the DTV signal to travel farther with more power, which should provide a consistent picture.

  Amplification isn't a guaranteed fix for every poor TV reception scenario but it is an option. It also isn't a fix for getting a TV signal when one isn't there - meaning an amplifier doesn't extend the range of the antenna. It merely gives the signal a push along its way from the antenna to the digital tuner (TV, DTV converter, etc.).

Troubleshoot Reception Issues before Amplifying a Digital TV Signal

  The problem with them is that they reduce the strength of the digital signal - meaning it isn't as strong leaving the component as it was entering it. Amplification could boost the signal above the minimum level your components need to produce a good picture.

  If you use an outdoor antenna then look at the type of coaxial cable connected between the antenna and line going into the house. Your coaxial cable could be the cause of a poor signal coming into the house.

  You'll need a DTV converter box in order to get the job done. In contrast, with analog TV you could record broadcast TV without a DTV converter box because the VCR had a built-in analog TV tuner.

  Digital satellite receiver are very popular these days and there are various types of satellite TV receiver with various features in the market and sometimes it can be really hard for you to pick up the right one for yourself. Basically there are two kinds of satellite TV receivers which are the Single frequency satellite receiver and the Dual frequency satellite receiver. The former one can support recording the show you are watching now and the latter one can recording the other show while you are watching another one.
