FIXING THE ANTENNA

As with any radio receiver, the quality of the output signal will be directly determined by the strength of the input signal that it receives.

Obviously the location of the tuner in relation to the transmitter will have a direct infl uence on the quality of the available signal, however it is important to pro-

vide the best possible antenna to the tuner to provide the best signal conditions possible.

We have provided with this DAB tuner a simple wire dipole antenna which is designed for internal use. Please see the following diagram for correct installation

procedure:

ANTENNA ADVICE

It is possible to display the signal strength as a bar graph on the LCD display by pressing the

rotary control knob once, this will show the following window:

The signal strength is determined by the number of bars which are illuminated towards the right , the stronger the signal, the more bars that will be filled. The 5th segment is shown with a

square outline, this determines the minimum reference point for adequate signal strength, and any signal below this point will be affected by poor or interrupted audio quality.

It is possible to adjust the signal strength by changing the position of the antenna, and by using the visual bar graph display it is possible to position the antenna for maximum signal strength.

Further enhancements can be made to the reception quality by purchasing a better quality aerial, available from most hi-fi retailers.

For best reception, we would recommend an external or loft mounted DAB antenna. There are two main types available, a) Dipole, b) 4-element aerial.

Diploe - for use in marginal signal areas, this type of antenna is omnidirectional and should increase the strength of all DAB stations being received.

4-element aerial - also for use in marginal or poor signal areas. This type is directional and has a high gain. Like a TV or FM aerial, this type of antenna needs to point at a transmitter. Installa-

tion requires someone to move the aerial whilst you monitor the signal strength. If you can receive signals from multiple transmitters you should point your aerial at the one which gives you the

best signal for the services which you want to listen to.

It is possible to use a TV or FM aerial with your DAB tuner as this is normally mounted externally. This may give a stronger signal than a simple internal aerial, however it would not be tuned

specifically for DAB reception. You would need to change the plug on your TV/FM aerial to an 'F' type, and it may also be necessary to use a signal booster to enhance the signal.
