• 4G – 4th Generation. For mobile phones using LTE standards
• ACTS – This stands for Advanced Communication Technologies & Services. An EU commission for research & development financing system which includes digital TV & Radio plus next gen internet
• Actuator – A motorised product that steers a multiple satellite dish to permit it to position itself at various satellites.
• AM – Amplitude Modulation
• Amplifier – A circuit that boosts the strength or voltage of a transmission
• Amplitude – The strength or size of a signal
• Analogue – A method of transmitting data. An Analogue waveform carries actual likeness with the volume it represents
• Anamorphic – Employed to distinguish a 16 x 9 image which fills up the entire frame, from a 16 x 9 letterbox with empty lines at the very top & bottom of your frame. The United States fails to identify anamorphic within the perspective of TV – their comparable phrase is 16 x 9 Full Frame
• Antenna - A Product which may acquire and or send radio frequency impulses whose formatting is dependent upon the kind of impulses used
• ASA – Authorised Sky Agent – An independent Satellite engineer & supplier who is authorised by BSkyB

• Attenuation – The reduction in strength of signals involving receptors and transmitters
• Attenuator – An inactive gadget that reduces transmission strength
• Azimuth – The side to side route conveyed as the angular range between the route of a fixed position, and the path of the subject.
  
• Balun - Is a balance-to-unbalance transformer (sometimes a fundamental element of an aerial) accustomed to match an unbalanced coaxial cable to some balanced device just like an aerial dipole or receiver input.
• Bandwidth – The entire selection of wavelengths occupied within a signal. It's usually measured by half-energy points.
• Baseband – A range of wavelengths that contains information after demodulation.
• Beamwidth - An aerial acceptance position measured between half- energy points.
• Benchmark – A certificate from an accredited authority.
• BER – Bit Error Ratio.
• Blue Tooth – Radio wave system used to communicate between devices over a short area.
• Boresight - The key centre axis of the aerial or satellite dish antenna.
• Bouquet – A group of programmes in a multiplex.
• Braid - The intertwined outer conductive layer of coaxial cable comprised of several bare conductors uniting to create a solid or nearly solid layer or shield. Braid is ranked by number of coverage by pixels per inch. Pixels per inch indicate the amount of crossings from the braid in a single inch of cable.
