Interference on overseas satellite TV equipment
Overseas free-to-air satellite TV equipment can react to other signals from licensed services operating nearby. This will cause interference on your overseas free-to-air satellite TV reception. This is a common problem.
These signals may be from mobile phone towers, mobile broadband internet or other signals on adjacent frequency bands.
Signals from mobile towers can interfere with TV reception in C-band (3.7 to 4.2 GHz), known as ‘big dish systems’.
This is due to signal overload of the low-noise block downconverter. The dish receives the strong signal that is close in frequency to the weak satellite signal.
We cannot help you with overseas free-to-air satellite TV interference.
Overseas free-to-air satellite TV signals are not protected from interference in Australia, and we are not able to help you with these issues.
Get help from a professional satellite dish technician. They can investigate the cause of the interference and if there is a way to improve your reception.
It may not be possible to fix the problems. You may always have interference on overseas TV. Consider this before you buy and install a satellite dish or call out a technician to look at the issue.
Investigate overseas satellite TV interference
As a professional satellite dish technician, it is important that you tell your customer that it may not be possible to fix the problem.
You can try to improve their satellite TV reception with these steps:
- Move the dish antenna to a more sheltered location.
- Use a low-noise block downconverter with built-in filters.
- Install a separate enhanced C-band filter to avoid signal overload.
