A multitude of commercial premises including hotels, offices and housing developments now look to utilise some form of structured cable system to supply an array of different programmes and services to any number of dwellings or end users. Digi-tel uk ltd specialise in all different aspects of digital installations and can tailor your system to meet your exact needs as well as your budget.
» M.A.T.V Systems (Master Antenna television)
M.A.T.V systems vary in size and complexity, the basic structure of the system comprises of two main elements:
1. A robust high gain aerial fitted to receive “off air” services (ANALOG 1-5 & FREEVIEW SERVICES)
2. A head end unit comprising of levellers, filters, launch amplifier, tap units and splitter units.
Brief over view of MATV installation:
A single high gain benchmarked aerial is fitted in a suitable location on heavy duty fixings and basketry. The aerial is aligned using the latest spectrum analyzer test equipment and is securely fixed to receive the required level on all analogue and digital frequencies. A mast head amplifier may be fitted to the aerial mast to improve the signals at the source before being carried to the main head end location. Here the signal will pass through a channel filter to discard any unwanted signals or interference. The signals are then levelled before being launched through a high gain high output launch amplifier into an array of tap units and splitters. The splitters then send the desired amount of signal to the end user down high grade low loss coax cable to a fully screened (to avoid interference) outlet socket.
» S.M.A.T.V (Satellite master antenna television)
This enhanced version of the previously described MATV system allows the end user to combine additional selected satellite programmes with the basic terrestrial(aerial) services. This kind of system is common and widely used in hotels. This kind of system can vary enormously depending on the required specification.
Digi-tel offer a free design and quotation service and are always willing to share their knowledge and experience to design a system to your exact requirements.
» I.R.S (integrated reception system)
This kind of system is fitted in nearly every new build for apartment blocks and living areas.
Installing IRS means that purchasers are free to decide to either connect their existing TV equipment to the system to pick up the existing analogue signals (until they are switched off), or to take up digital satellite or digital terrestrial television, now or in the future. This solution means that the builder installing IRS does not have to favour any one particular supplier of TV programming. The choice is left to the customer.
IRS collects the broadcast signals from terrestrial (analogue & digital) and satellite transmitters, as well as FM radio and the new Digital Audio Broadcasts (DAB). All of these signals are then distributed via a single cable to a 3 socket wall outlet plate for standard sky or by 2 cables to a 4 socket wall plate for sky plus in the main rooms of the home, the cables are screened from electrical interference and the system can deliver all available TV channels to the resident, including bothanalogue and digital terrestrial, and digital satellite. IRS systems are equally suited to multiple dwelling units or single homes.
» 9 Wire Communal Systems
Including analog 1-5, Freeview, Sky, Sky+, and a European or second satellite of customers choice.
Digi-Tel can design, supply and install a more complex nine wire system offering the end user even more choice than the traditional IRS system.
This enables any number of dwellings to be fed from one antenna. The system still offers the same great facilities of Sky+ functions as well as the capacity to have a second satellite receiver on any chosen satellite.
Digi-Tel offer free consultations and site surveys and will always take the time and effort to find the most suitable system to for fill your needs and budget.

» TV Over CAT 5
This kind of system is becoming ever more popular in large scale buildings and development due to the long distance the cables can be run, upto 300 meters without signal loss or compromise of picture quality.
Structured Cabling schemes based on Cat 5, cat 5e and cat 6 cabling (generically known as UTP cable) are commonly installed to distribute voice and data services in the work place. Digi-tel systems enable TV and video to be distributed over structured cabling as well, providing all the functionality of coaxial cable based Cable TVand SMATV distribution systems without the need to install coaxial cable. TV and video distribution over structured cabling should not be confused with more sophisticated IPTV technology which distributes TV and video over data networks as streams of data which co exist with other data on the network.
To distribute TV over Cat5, the TV signals are received and demodulated to baseband video + audio signals. For example, in the case of Freeview channels, the signal received by a TV antenna is processed by a Freeview Set Top Box (STB) to produce video + audio signals at its output. Several sets of video + audio signals derived in this way are input to a video over Cat5 switch which enables users connected to the output of the switch over Cat5 cabling links to select the input they wish to view.
All work carried out by digi-tel conforms to the CAI (Confederation of aerial industries) codes of practise and is fully guaranteed for a period of 12 months. All equipment utilised in the construction of our systems is CAI bench marked and approved. All system components are earthed to comply with current legislation on electrical safety. Certificates are issued on completion of all systems and demo sheets are supplied if required. further type maintenance type agreements are available after the 12 month period.
