6 There are a number of types of aerials currently used for TV. These are pointed towards the transmitters to get the strongest signal.

7 VHF (Very High Frequency) with a few large elements. The double element (dipole) receives the signal. The longer element behind reflects the signal. One or more shorter elements in front direct the signal onto the dipole. The more front elements, the stronger the signal that is received. These are in two sizes, for different sets of analogue channels (Channels 1 – 3, Channels 4 – 9). The larger size is shown here. VHF aerials will no longer be used after the change-over.

8 UHF (Ultra High Frequency) aerials are required for Channels 21 – 69. These are needed at present for some analogue channels: Central (Ch. 40), Maori (Ch. 44), Prime (Ch. 56), Trackside (Ch. 60). A UHF aerial is required for Terrestrial Freeview (Channels 46, 48, 50, 51). Note the number of front elements in these examples (more mean better reception).

9 A dish is required for Satellite Freeview. The dish is a reflector which receives the signal and reflects and focuses it to the receiver in front of it. The dish is pointed towards a stationary satellite to get the strongest signal.

10 Terrestrial Freeview provides better picture quality (HD = High Definition), which is available on some programs on some channels. If you currently have a UHF aerial and receive a reasonable picture for Prime and Maori channels, then use Terrestrial Freeview. Otherwise use Satellite Freeview. This will be necessary if you are not in an area where Terrestrial Freeview can be received (e.g. too far from the transmitter, behind hills). If you already have Sky Television, you can have both Sky and Satellite Freeview from the dish, or you can have Sky with the dish and Freeview Terrestrial with a UHF aerial. After having Terrestrial Freeview installed you may find that the picture often “breaks up”. In this case you may need a line amplifier, or a better UHF aerial, or you may have to use Satellite Freeview. It is best to have an aerial installer check your location and install a suitable aerial or satellite dish before you purchase Freeview.

11 Information about reception in your location can be found at

These receiver, with internal hard drives for recording, are called “My Freeview”.

17 Connecting Freeview to a TV This will depend on the input connections on your TV set. Rear of Freeview Terrestrial receiver is shown.

19 Many TVs now include Freeview (the example shown is one of these). These have Terrestrial Freeview, and can’t be used with a satellite dish. Inputs on this set: 3 HDMI, 1 VGA (from computer), 2 sets of Component Video, 2 sets of AV (Audio L/R, Composite Video), S-Video, Aerial Outputs: 1 set of AV (to connect to VCR recorder), Headphones. A DVD player (below the TV) and aerial are connected.

34 The input is selected using “Source” on the remote. A menu appears on the TV screen DTV = Digital TV ATV = Analogue TV AV1,2 = input from VCR or DVD player Component 1,2 = input from DVD player, Freeview, or other decoder (e.g. SKY) D-SUB = input from computer HDMI 1,2,3 = input from DVD player, Freeview, or other decoder (e.g. SKY)

35 The channels which are available are automatically located and listed when you first switch your set on — it’s quick and simple. The channels (from 21 to 69) are scanned, and as Freeview channels are located they are listed.

36 Note that when switched off the unit is still on stand-by, and is using electricity (possibly 1 Watt or more) Get into the habit of switching the TV and Freeview off at the wall when not being used. On/off, selection of channels, menus, and many other functions are available on a remote.

49 Electronic Program Guide When the EPG button is pressed, “Loading” appears in the screen. The current and following programs for that channel appear. The picture is reduced in the top right. Below the picture there is a brief description of the program. Clicking on the ▲ or ▼ buttons on the remote shows earlier or later programs that are not shown on the screen. Clicking on the ► or ◄ buttons shows other channels. Clicking on the or buttons shows the programs Next Week or Next Day.

50 Recording with My Freeview Recorder When a program is selected in the Electronic Program Guide, clicking on the button records the program. A button on the remote opens the “Record List” which lists programs to be recorded. Another button opens the “Play List”, from which the programs can be played.

51 Aspect Ratio Analogue Standard TVs (and most computer monitors) have an Aspect Ratio (Width:Height) of 4:3. The sides of full widescreen pictures are cut off when broadcast on analogue channels. Freeview TV is Widescreen, with an Aspect Ratio of 16:9 (note that 16:9 is 4²:3²). This is the Aspect Ratio of newer TVs, and some computer monitors, especially laptops. When Freeview TV is on a screen with 4:3 ratio, the full picture is seen (but is smaller), and there are grey bars at the top and bottom.

52 74cm = 29” 59cm 44cm 67.5cm = 26” 59c m 44c m 74cm = 29” 59cm 44cm If you have a 29” (measured corner to corner) TV with 4:3 Aspect Ratio, the picture size is 59cm by 44cm. A widescreen Freeview channel picture with the same width (59cm) is only 33cm high. This picture on a 29” TV with 4:3 Aspect Ratio is the size on a 26” TV. 59cm 33cm 67.5cm = 26”

53 Some older programs shown on Freeview TV may have been recorded in 4:3 ratio. There will be grey bars at each side on a Widescreen. On a 4:3 screen there will be grey bars on all sides. You can enlarge the picture using “Zoom” on the remote.
