Aerial / Antenna – Designed to receive electromagnetic waves (radio waves), this is the pointed piece of metal that sits on top of your TV, on the roof or in your loft.
Amplifier – If you are struggling to receive a TV signal, often it can be down to a poor aerial. In some rural areas, sometimes an amplifier is recommended – it does exactly what you think by amplifying the whole signal. However, while many think it's the easiest way to fix the problem in many cases an amplifier or a signal booster won't work.
Analogue – Analogue has been the norm for TV and Radio broadcasting since it first originated. Using a continuous signal of varying intensities, your TV or Radio converts that carrier signal into image or sound.
Aspect Ratio – Aspect Ratio is essentially the proportions of your TV screen. Traditionally TV screens were rather square, using what's known as a 4:3 aspect ratio, however nowadays widescreen TV has started to use the much more natural 16:9 aspect ratio which is essentially more of an envelope shape, which is more natural for the eyes and more realistic.
Wide Band – A Wide Band aerial is designed to pick up more frequencies than a traditional UHF aerial and it can increase reception for those in poor signal areas. It's one of the best ways to boost signal strength.
CAI – Certified Aerial Installers – AerialTec are CAIPlus members which means we're certified, qualified and experienced when it comes to installing any type of aerial. Our team are CRB checked and all carry public liability insurance giving you the peace of mind you need to let us perform fantastic work on your behalf.
CAT5 – Category 5 is the standard type of cabling used for Ethernet networking. It's also used in patch panels and office cabling as it can carry both voice and data with ease.
Coax – Coaxial Cable is the cable that normally runs between your aerial and TV. This cable should be relatively thick and inside there are multiple layers. Coax has been used since the early 1900s and RG-6 is the most common type used for TV. On older setups, unexpected signal loss can be attributed to coaxial cable which has been exposed to the elements for too long.
Composite Video – Composite video is essentially the part of the video signal without 'audio'. It's combined of three main signals known as YUV which represent different colour spaces namely RGB (Red Green and Blue). Most Televisions have composite video ports for backwards compatibility, but the technology has largely been replaced by SCART.
SCART – A SCART lead is a 21-pin oblong connector that's became common place in the industry. It's been widely regarded as the precursor to HDMI, and today, most televisions have at least one, if not two SCART ports. You can use SCART to connect set top boxes, DVD players, Hi-Fi systems and even more.
DAB – Digital Audio Broadcasting is the next evolution of FM radio and instead of using an analogue signal to broadcast radio, it digitizes the signal reducing white noise and creating a cleaner, crisper experience. DAB can also be broadcasted with radio text telling you information about songs and radio stations.
Dead Pixel – If you buy a new LCD TV and there's a dot, or a group of small dots that are always the same color, normally red, green, blue or white, and it won't change color no matter what you do, chances are it's a dead pixel. While for the most part it's only a cosmetic glitch, if your TV has many of them it's usually grounds to request a replacement under warranty.
Digital Terrestrial TV – Digital Terrestrial TV is the evolution of Analogue TV. Still using the radio airwaves to broadcast the signal, Digital Terrestrial TV digitizes it allowing hundreds of channels instead of just a handful.
DVR – A Digital Video Recorder is essentially the evolution of your VCR. Instead of recording to video tapes, a DVR can record direct to an internal hard disk which can often store hundreds of hours of programmes. Many DVR recorders also have DVD drivers allowing you to record direct to CD and or DVD.
DSP – Digital Signal Processing
DTS – Digital Theatre System is a sound system that many home cinemas support and DTS is essentially a rival to the popular Dolby sound systems.
Dolby – Dolby pro logic, Dolby AC-3 and Dolby Digital are examples of high quality sound encodings that allow you to enjoy fully features surround sound at home. Dolby True HD is their latest incarnation and it can support up to seven 96 kHz sound channels ensuring an unforgettable audio experience.
LNB – The LNB is the component that sits on the arm of your satellite dish.

Sky+ - Sky+ was the first mainstream PVR service launched in the UK and it allowed Sky subscribers to upgrade their set top box to a box with a built-in hard disk drive. The revolutionary thing about Sky was that it allowed people to pause TV shows and come back later. Today subscribers can schedule recordings remotely, and Sky+ has been a massive hit in the UK.
Sky+ HD Sky+ HD was the first major HD service launched in the United Kingdom and it offers the widest range of HD channels currently available. With Freesat and Freeview both lagging behind considerably, a Sky+HD subscription is practically essential if you're an HD aficionado.
