The Confederation of Aerial Industries (CAI) has been set up by representatives of UK television aerial manufacturers to govern a voluntary benchmark scheme which aims to standardise the performance of commercial digital TV aerials.

NPL performs the benchmark testing on the (60 m by 30 m) ground plane.

The benchmark procedure consists of 5 tests:

• forward gain
• polar pattern
• cross polar
• return loss
• feeder pickup

By request we offer a site hire facility, which allows manufacturers to develop their aerials prior to the formal benchmark test. This service is charged at a daily rate.
