FAQs.(Frequently.Asked.Questions)
Why.have.I.lost.some./.all.of.my.
channels?
• It happens sometimes, if you have a weak signal. Usually it just means you’ll need
to rescan your digital box or TV. Don’t worry, it easy to do. And once you’ve done it,
you should get all the Freeview channels available to you. If problems persist you
may need to get your aerial checked. Talk to your retailer or contact your local aerial
installer.
Why.do.I.get.‘blocking’.on.my.digital.
picture?
• In most cases, blocking is caused by a reception problem – either the signal is too
weak or there is some kind of interference. Talk to your retailer or contact your local
aerial installer.
• Blocking can also be caused by a digital signal that is too strong. If you are still
experiencing blocking and the signal is strong, consult your local aerial installer for
advice.
Can.I.watch.Freeview.using.a.
portable.set-top.aerial?
• Some, but only a few, homes may be able to use a set top aerial. However, for a
much better reception, we strongly recommend that you use a rooftop aerial.
• If you do not have access to a rooftop aerial – for example, if you rent a flat and
the aerial is the responsibility of your landlord, or if you’re using a second TV in
the bedroom and don’t want the hassle and expense of using extension cables,
a set – top aerial may be your only option.
What.type.of.aerial.do.I.need?
• If you are installing a new aerial, we recommend a wideband rooftop aerial rather
than a loft aerial. Loft aerials generally receive a weaker digital signal and are more
likely to get interference from other electrical devices in the home. We suggest you
have an aerial survey done before getting an aerial upgrade.
• Talk to your retailer or contact your local aerial installer.
