Connecting to the TV aerial
You can connect the Mediamaster to the following type of aerials:
1. Standard outdoor aerial
Where possible, use an outdoor roof aerial intended for receiv-
ing UHF channels between 21 and 69.
Please note the following:
• In some block of flats, the roof-mounted aerial system includes
a filter and channel selector. If so, the aerial will probably not
work with the Mediamaster. Please consult the landlord.
• Many older roof-mounted aerials may only receive a limited
number of channels. As a result, digital channels transmitted
on higher frequencies are difficult or even impossible to re-
ceive. The problem can be solved by replacing the roof aerial.
• Some outdoor aerials are directed towards an analogue trans-
mitter. The aerial must be directed towards a digital TV trans-
mitter.
• It is not always advisable to position the aerial as high as pos-
sible. If problems arise, experiment with different aerial
heights.
INSTALLATION OF THE MEDIAMASTER
About the digital transmission
Digital Radio and TV signals can be blocked by buildings, moun-
tains and the terrain. Depending on if the receiver is located in a
depression in the ground, behind a mountain or in a concrete
building, the quality of reception may vary considerably.
A digital signal can be “boosted” if reflections of it (from e. g. a
building) are added to the original signal.
Reflections can be used for reception by directing the aerial to-
wards a mountain or a high building, providing that they do not
block the transmitter.
As with most other transmissions, bad weather does affect the
reception quality negatively.
2. Indoor and window-mounted aerials
This type of aerial may be enough if the reception conditions are
very good. If an indoor aerial is used, please note the following:
• Use an aerial for UHF channels 21 - 69, such as a directional
aerial.
• Place the aerial by the window and directed towards the TV
transmitter, if possible.
• An aerial with an amplifier is recommended as it may provide
a stronger signal.
• The strength of the TV signal varies according to reflections
from e. g. buildings. The signal penetrates thick stone or con-
crete walls poorly. However, a wooden building is not a big bar-
rier to digital TV signals.
