Digital Tv Antennas
A Guide to Digital TV Antennas
For many years, most households have been subscribing to cable and satellite coverage. This gave them a host of channels to choose from for their viewing pleasure. Today, however, the trend is getting towards going back to the old ways of getting TV channels and that is through a digital TV antenna. People have stopped paying for cable and satellite subscriptions and are now back to relying on digital TV antennas for their source of content.
How does a TV antenna work?
Digital TV antennas are wires that pick up signals from television networks. If you want to watch shows that are broadcasted by your local TV stations, then you are required to have a TV antenna. The signals from the broadcast stations are received by the antenna and convert it to audio and video signals that are displayed on your TV, whatever program you are watching.
The broadcasts that you will get on your TV are from the local stations near your home plus the broadcasts made by major networks like SBS, ABC, Channel 7, Channel 9, Channel 10. Your location will determine the number of local TV stations you can receive on your TV. You can pick up the major networks since they transmit in every major city across the country and you can also pick up stations that are near to your location.
With an HD antenna, you can get a better image and sound quality than cable and satellite TV. The reason for this is that cable and satellite transmit compressed signals so that they can provide more data to viewers. However with local stations, the signal that is being received is uncompressed. This explains why you get higher quality sound and video.
Over-the-air television is free. Most cable subscriptions do not carry some of your local channels. But with a TV antenna, you can get additional regional programming for free. You can get local news, kids programming, cooking shows, sports channels, classic TV shows, and movies. It is also free for major broadcasters since these are paid for by advertisers.
What types of antennas are there?
Before choosing an antenna, however, you need to locate where the broadcast towers are so you can have a better signal. Your antenna set-up at home will be unique to your location. Remember also that digital TV signal is a line of sight signal. So, hills, trees, and buildings can weaken the signals since they are deflected and bent by these objects. If you put your antenna high enough you will get better reception. Signals can get weakened with obstruction. If you want your antenna to perform at the highest level, you need to make sure that it has a clear, unobstructed view of the broadcast towers. This is why you need to point your antenna towards the broadcast tower locations.
Outdoor antennas are best but you can also install indoor antennas or attic antennas but you can lose half of its strength and range indoors. It is also best to have a simple, direct connection instead of having a lot of junctions to your antenna since more junctions will give you a higher signal loss.
When installing your antenna, move it to different locations to find where the signal is. There are some parts of your room where you get a better signal than other parts.
