GLOSSARY
Receiver: Equipment that allows you to receive digital TV, like Free To View channels.
Analogue Channels: Nature of the signals used for terrestrial television since the
middle of the 20th Century. Since digital has come along, analogue will disappear
(starting 2008).
Network: Number given to a frequency band. In UHF, networks are numbered from 21
to 69.
Transmitter: Pylon that transmits digital or analogue signals, and towards which your
antenna must be pointed.
EPG: Electronic Program Guide.
FTA: Free To Air = free channels.
Digital: Nature of the signals used in modern transmissions. Digital allow you to view
more channels than analogue. Digital channels have existed for a few years on satellite
and cable. They will replace the terrestrial analogue channels. One channel (e.g. BBC1)
can be transmitted both in analogue and digital.
Polarization: Orientation of the transmitter wave. Most UHF transmissions are
horizontal. The elements of your aerial must therefore be horizontal.
Terrestrial: Refers to transmissions in the air, as opposed to cable or satellite.
