In Australia, digital TV signals are aired on both VHF and UHF frequencies (the signals are electromagnetic waves and the frequency is the number of waves transmitted in one second). UHF signal has a higher frequency than VHF and is vertically polarized in Brisbane, while VHF TV signal travels in the horizontal plane.
The majority of digital TV stations currently broadcast in the UHF band, both because VHF was already filled largely with analog TV when the digital facilities were built and because of severe issues with impulse noise on digital low-VHF channels.
What are VHF and UHF TV Frequencies? In the US and Canada, the VHF television band occupies frequencies between 54 and 216 MHz and the UHF band between 470 and 608 MHz. In general, VHF channels are numbered 2 to 13 and UHF channels 14 to 36.
A VHF (Very High Frequency) antenna is required in places where VHF television is accessible. However, most television signals are broadcast on UHF (Ultra High Frequency). Even when UHF is utilised, there are many bands.
Digital terrestrial television signals in Australia are broadcast in VHF Band III (VHF channels 6–12) and UHF Band IV and V (UHF channels 28–51). Your antenna needs to be designed to receive the particular television frequencies in your area.
Antennas for Receiving DTV
To receive DTV signals from all stations in the area, your antenna needs to be able to receive both VHF channels (channels 2-13) and UHF channels (channels 14-36). Some antennas only provide good reception of VHF or UHF channels, but not both.
Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 36 and occupies frequencies between 470 and 700 MHz.
For TV aerial reception and terrestrial TV services the Ultra high frequency (UHF) band is used.
While VHF is used for FM radio and television broadcasting, it is also utilized to broadcast military and local mobile radio, traffic control, radar, radio modem and marine and air navigation systems transmissions. VHF television channels are typically 2 through 13.
You will be pleased to know that all you need is an internet connection. While you do not need an antenna, you have to watch your content over the web. Online platforms such as Freeview can help you get digital TV services over the web. Freeview brings together several channels which you can access via any browser.
Analogue technology was phased out completely so that now only digital televisions receive audio and video signals. All the Australian free-to-air television networks are now available on digital televisions and smart TVs, but if you still have an analogue TV, you can access them with a digital set-top box.
Do Smart TVs Need An Antenna in Australia? A Smart TV does not need an antenna in Australia. A Smart TV will work without an antenna, it just won't be able to receive Freeview channels. You can setup a smart TV without needing to install an antenna.
Because wideband (T or W) aerials cover the entire range of signals used to transmit digital TV.
TV channel frequencies are assigned in 54 to 806 MHz RF frequency band. These total spectrum is divided into 68 TV channels. Each channel occupies 6MHz bandwidth. To calculate picture carrier value, add 1.25MHz to the lower frequency range.
90% of Metro Melbourne is covered by the broadcast tower at Mount Dandenong which transmits Digital TV through VHF.
If you have UHF coverage, it's best to use a UHF aerial because you can pick up broadcasts in high definition via a UHF aerial (but not through a satellite dish).
In a general sense, UHF's shorter radio waves make it best-suited for wireless and indoor use, where there are more penetrable obstacles. On the other hand, VHF is excellent for outdoor use; construction workers, aviators, and boat captains rely on VHF radios on their crafts.
TV channel 3 (VHF) broadcasts at a frequency of 63.0 MHz, channel 23 is a (UHF) frequency of 527...
UHF channels for general use
Channel 10 for 4WD clubs or convoys: This is the default general use channel, except if your club chooses to use a different channel.
VHF has smaller frequencies which means interference with other radios is common. UHF, on the other hand, is an all-around better signal for long distance communication. UHF is better when using radios for indoor use like buildings or around cities.
"Antennas made for analog TV signals work just as well for both digital and high definition signals.
What Do Digital Antennas Look Like? Digital antennas come in a wide variety of different shapes. One of the most popular options on the market is a simple flat square that you can mount above your TV or put on the TV stand. They're extremely thin and tend to blend in with the surroundings.
TV broadcasting in North America is spread across three frequency bands: VHF-Low (channels 2 through 6), VHF-High (channels 7 through 13), and UHF (channels 14 through 51). Because of the different frequencies in use, antennas are designed to cover one, two, or three bands. Not every antenna covers them all.
