Most households are now increasingly aware of the ongoing transition from terrestrial analogue to DTT (Digital Terrestrial Television) currently being implemented across the country. Indeed the Government have announced their intention to cease all analogue transmissions within the next 5 years leaving DTT as the only format of receivable terrestrial television available.
With this in mind D.A.B DIGITAL have introduced a company policy of installing DTT compatible equipment to all of our customers, irrespective of whether they require digital signals at the present time or not . Therefore all of the equipment installed by D.A.B DIGITAL must reach the criteria set down by the broadcasting authorities in order to receive clean DTT signals. This includes the following
- The aerial itself must have a balun built within the connection box. This is a device that should stop any unwanted electrical interference disrupting the signal quality.
- The cable must be double-screened. This is an extra barrier of copper foil built around the underneath of the cables' external casing to stop any unwanted signals breaching through.
- If an outlet socket is installed it must also be double-screened. This means that it must have a protective metal casing screening the connections from any unwanted signal ingress.
- The antenna must be sited in a position that is clear of interference source, particularly mains wiring, and it is always preferable to install the array outdoors as loft mounting will usually lead to excessive interference pick-up and disappointment.
- Signal measurements must be taken at each site and the results must equate to the parameters set by the broadcasting authorities. If the results obtained are outside of the required criteria then the installation will simply fail to work properly
D.A.B Digital Install only the best products which include Digital Ready Aerials (Benchmarked by the CAI)), Galvanised Steel Brackets, Heavy Duty Alloy or Galvanized Steel Masts, Fully Screened Cable and Wall Plates and Fully Screened Amplifiers
