Television Antenna Installations, Types and Recommendations
The switch to Digital TV broadcasting has eliminated annoying picture distortion, snow and ghosting, all of which made it so difficult to achieve a good analogue signal throughout Brisbane and its outer suburbs. By contrast Digital TV signals (both standard and high definition), will deliver crisp, clean, ghost-free pictures.
Even if you have an old free-to-air antenna installed, there are several good reasons to consider replacing your old antenna with a new Digital Antenna.
Digital TV is now available to almost all Australians. While the widest selection of Digital TV channels are found within metropolitan areas, coverage extends to most regional households which can access at least one local digital station while 89% can receive five or more stations. You can find which stations provide digital content within your local area by visiting the My Switch Website.
Free-to-air Digital reception provides the best picture quality. Cable and satellite providers offer a wider range of channels, but to do this they use data compression or other techniques that compromise picture quality, resulting in a "soft" image, distracting video artifacts (pixelation), or both. Free-to-air antenna reception is the best way to enjoy HDTV programs at the full resolution as intended.
Free-to-air signals are free. – apart from the cost to purchase a digital television and install of your new digital antenna, receiving Free-to-air HDTV is free.
Access all of your favourite local channels – cable and satellite providers do not always carry the local channels in your area, or may not offer them in high definition. Also, contract agreements between local cable operators and local broadcasters can mean that high definition is only available as a paid add-on.
Why pay an additional fee for something that is transmitted free in the first place?

An onsite survey is the only way to truly ascertain the direction, signal strength and quality of Digital TV available to your home. This is part of our Free Quote offer for residential customers. Commercial properties may incur a small service fee which will be included in the final cost when you accept our quote.
AETV Systems utilises the latest quality Australian and European digital television antennas. All antenna installations are covered by a 12-month warranty on manufacturing quality and workmanship.
Logical Periodic a broadband multi-element unidirectional narrow-beam antenna that has impedance and radiation characteristics that are regularly repetitive as a logarithmic function of the excitation frequency. Note: The length and spacing of the elements of a log-periodic antenna increase logarithmically from one end to the other.
"UHF (Ultra High Frequency) range of the radio spectrum is the band extending from 300 MHz to 3 GHz. UHF Phased Array antennas are suitable for receiving Channels 21 to 69. UHF Yagi antennas are available in Band IV Channels 21 to 51 Band V Channels 52 to 69 or a combination of both"
"Combination antennas are constructed to receive both VHF and UHF signals. Constructed with the shorter UHF elements at the front of the boom followed by the longer VHF elements at the back. Digital combination antennas normally receive bands III VHF channels 6-12 and UHF Bands IV & V 28-50."
"The VHF (very high frequency) range of the radio spectrum is the band extending from 30 MHz to 300 MHz. The wavelengths corresponding to these limit frequencies are 10 meters and 1 meter. High gain Band III antenna on the left is suitable for receiving Channels 6 to 12 with wide Band I-III antenna suitable for Channels 2 to 12 analogue/digital. In the VHF band electromagnetic fields are affected by the earth's ionosphere and troposphere. Ionospheric propagation occurs regularly in the lower part of the VHF spectrum mostly at frequencies below 70 MHz. In this mode the communication range can sometimes extend over the entire surface of the earth."
Yagi a highly directional and selective shortwave antenna consisting of a horizontal conductor of one or two dipoles connected with the receiver or transmitter and of a set of nearly equal insulated dipoles parallel to and on a level with the horizontal conductor.
