Your roof top aerial may the TVs in your house with a strong signal, but every extra cable you attach can reduce the reception quality on your devices.
It’s not just TVs that eat into this signal. Almost anything connected to your aerial can cause the signal to drop slightly
What usually happens is that you get to a point where some channels don’t get enough signal to display properly. When this happens you get blocking, picture and sound break up, and missing channels.
There are a few things you can check which may help:
- Retune your new TV without any cable, video/DVD recorders or Freeview boxes attached
- Try switching the TVs in each room
You may find that with a little reorganisation you can get all channels on all your TVs.
- Unplug all the other TVs and retune your new TV
If you are lucky you may find that your TVs work fine afterwards.
Failing this you could consider:
- Your aerial
Depending on the age and type of aerial, this may need changing or servicing. A qualified aerial fitter should be able to advise you further.
- A signal booster
Installing a signal booster in the loft can help strengthen the signal and clear up your reception problems.
