Analog to Digital Advantages
Switching from analog to digital lets broadcasters offer higher picture definition, because a digital signal can be compressed far more than an analog signal. Compression allows stations to fit more information in the signal. That means you’re getting a clearer image with digital television than you would from an analog signal. In fact, even though digital signals get weaker with distance, just as analog signals do, digital signals won’t degrade in quality. As long as you have a signal, you’ll get a clear picture.
There’s another advantage of having additional bandwidth available. Using digital broadcasting, local stations are able to offer more programming to their viewers than they could with an analog signal. How? Multicasting, or broadcasting several shows within a single frequency.
Broadcast TV stations in Australia are currently switching from analog to digital transmissions.
This Fact Sheet provides information on TV antennas and tips for obtaining good quality reception for digital broadcasts.
What Kind of Antenna Do I Need to Receive Digital TV Signals?
To receive digital TV signals from all stations, it is important that your antenna is able to receive both VHF channels and UHF channels. Some antennas only provide good reception of VHF or UHF channels, but not both. For example, indoor “rabbit ears” usually need to be replaced in order to pick up signals on UHF channels. Local Bloke Antenna Services only stocks quality antennas capable of receiving a digital signal.
The reception capabilities of TV antennas also vary considerably, so be sure to talk to a quality installer such as Local Bloke Antenna Services.
Antennas for Reception in Different Signal Conditions
A standard antenna will work for the required signal strength in most instances, but may not work in all cases. Indoor reception of TV signals may be affected by factors such as nearby buildings, trees, terrain, or home construction.
All Local Bloke Antenna Services technicians carry a digital field strength meter so they can asses your individual signal needs. In some cases you may need a larger antenna, mount, or booster to receive a quality signal which Local Bloke Antenna Services can install for you. Note that the type of antenna needed at a specific location may vary depending on geographic location, the height at which the antenna is used, the presence of nearby structures and other local factors.
Digital TV reception can often be improved just by changing the location of your current antenna, even as little as a few inches. Using a digital Field Strength Meter a Local Bloke Antenna Services Technician can find the perfect location for your antenna. Antennas typically need to be oriented or “aimed” to get the best signal from the desired station.
Generally, an outdoor antenna will get better reception than an indoor antenna. If you are near a station’s broadcast tower, reception of that station, as well as other stations, can be impeded by strong signal “overload.” which means a Local Bloke Antenna Services technician may need to adjust your signal reception.
