An aerial and satellite engineer is a specialist who installs, aligns, repairs and maintains TV reception equipment including rooftop aerials, satellite dishes, loft aerials and communal aerial systems. The trade is not formally regulated but the CAI (Confederation of Aerial Industries) provides a recognised quality standard - CAI registered installers commit to a code of practice, hold appropriate insurance and are assessed on their technical competence. For communal MATV or SMATV systems serving blocks of flats, installer experience with signal distribution, multi-switch design and head-end equipment is essential.

Qualifications to look for
CAI registration is the primary quality indicator for aerial and satellite engineers. CAI members commit to a code of practice, hold adequate insurance and are assessed on technical competence. Verify at cai.org.uk.
The City and Guilds 3667 qualification covers aerial installation, signal measurement and fault diagnosis. Held by qualified aerial engineers alongside CAI membership.
How to find a reputable aerial and satellite engineer
Frequently asked questions
How do I know if I need a new aerial or just a repair?
A signal survey by a CAI registered installer will identify whether the issue is with the aerial, cable, connections or tuner. Repair is often possible but aerials over 15-20 years old or those with visible corrosion or damage are usually best replaced.
Do I need permission to put a satellite dish on my house?
Satellite dishes up to 100cm diameter are permitted development on most houses and do not require planning permission. Restrictions apply to listed buildings, conservation areas and some flats - check with your local planning authority.
What is an MATV system?
Master Antenna Television - a communal aerial system serving multiple dwellings from a single aerial installation, typically used in blocks of flats to avoid multiple dishes and aerials on the building facade.
