High Gain TV Aerial – Fracarro Blu 420 Plus
This high gain TV aerial is CAI benchmarked to standard 2. The CAI (Confederation Of Aerial Industries) are the recognised body for the aerial and satellite industry. The group is comprised of TV Aerial and satellite installers, manufacturers, broadcasters and other members. Their aim is to raise standards and improve the industry. CAI benchmarking is done on TV Aerials and Coaxial Cable. This is done so that manufacturers can certify that their equipment meets certain standards. The CAI will randomly asses and test equipment from these manufacturers once they have achieved a benchmark standard. Equipment benchmarking is done on a voluntary basis so don’t be put off if the TV aerial you are interested in isn’t benchmarked. It might just mean that the manufacturer hasn’t submitted the TV Aerial for benchmarking.
There are 4 CAI benchmark standards for TV Aerials at the moment, each used for different classes of TV Aerial:
CAI Benchmark Standard 1 -This standard means that the TV Aerial will provide adequate Freeview signals in areas that are on the edge of digital signal coverage.
CAI Benchmark Standard 2 -This is an intermediate standard bridging 1 and 3, meaning that the TV Aerial will be suitable for use throughout the TV signal coverage area.
CAI Benchmark Standard 3 -This standard provides a minimum for signal in primary coverage areas.
CAI Benchmark Standard 4 -This standard covers TV Aerials that are of a specific design to meet a specific need, such as an aerial needed with a very narrow beamwidth but high wideband performance.
All Fracarro TV Aerials and equipment now come with a 4 year warranty.
