LNB or Low Noise Block simply refers to the feature present at the end of a satellite dish which is attached to the coaxial cables feeding the satellite receiver. There are varying types of LNB which all works in their own special way, however a general function they all provide is to serve as the satellite broadcast signal amplifier and oscillate the signal to a lower frequency band which can be contained by the coaxial cable without too much loss of the cable and the greater the frequency the better the cable resistance and the quicker you’ll lose signal as a result of the cable strength. It should, however, be noted that most LNBs (and not all), oscillate the signal down to the satellite intermediate frequency band ranging from 950Mhz to 2150Mhz.

With the availability of a wide range of LNB types, makes and models, picking the right one for your satellite is crucial as the wrong one may imply your satellite will not work. The most common LNB types are single LNBs and Quad LNBs. The major difference between all types is the amount of output possessed by each LNB. This is what allows extra satellite receivers to be added for additional TV points as well as the inclusion of satellite PVRs which features recordable, play, pause and rewind TV services. For example, a single LNB possesses just one LNB connection for a coaxial cable to be attached. This allows you to connect a standard satellite receiver such as Freesat box or Sky. There are also dual or twin LNB, quad LNB and octo LNB which allows for two (or one satellite PVR), four (two PVRs or one PVR and two standard satellite receivers) and eight separate satellite receivers (four PVRs or combination of both) respectively. There are many other LNB types you can choose from with varying features, so it all depends on your requirements.

No, you will need a satellite dish to receive a satellite signal for services like Sky or Freesat, as these are specific channels and programmes only broadcast via this medium. These can be installed in a similar way to a standard TV aerial by a recognised engineer.

The process you need to go through to install a TV aerial depends on the type of aerial you have. If you have an indoor aerial, it’s simple. Just plug the aerial into your TV and stand it up next to it. If the signal isn’t right, then try moving your aerial closer to a window or higher up. Make sure you rescan for channels every time you move it so you know if you’ve made an improvement. It’s also fairly easy to install a loft TV aerial – just take it up into your loft and position it in a convenient place. Again, experiment with angles and positions to ensure you get the best signal. Installing an outdoor TV aerial is a little trickier. Ideally, try to fix your aerial to a wall or chimney at a gable end – this will be much easier to access than a chimney in the middle of the roof. Follow the instructions that come with your aerial for mounting it – it’s usually best to lash your aerial on rather than use screws. If you’re not used to working at height or aren’t confident doing your own aerial installation work, it’s best to get in touch with a professional.

Generally speaking, you do need an aerial if you have a smart TV. This what will enable you to watch live TV. However, if you’re not bothered about live TV, and just want to use services like Netflix, Amazon Prime and Youtube, you don’t normally need a TV aerial. This is because these services use the internet instead.

Freeview is only available through a TV aerial. You can’t access Freeview using the internet, so you’ll need to invest in a TV aerial if you haven’t got one already.

If your TV picture is pixelated, poor quality, or cutting out, there may be a fault with your aerial or the cables connecting it to your TV. Also your aerial may not be located in the correct place. An experienced aerial company can carry out a survey to discover the fault.

Basically, what a tv aerial does is simply to receive broadcasted tv signals from the television station, then transmit those vibrations directly to your screen. Just like any other antenna, the tv aerial is made of metal. How exactly does it work?

The small electrical currents present in the antenna is induced by the electromagnetic waves transmitting tv signals. The tv set then acts as an amplifier to the signal and chooses the information which carries the sound as well as vision. The tv aerials are also commonly referred to as “yagi arrays by engineers. The metal plates present at the far end of the array directs the signal back down its length. Meanwhile, the parallel rod-like structures which run along the aerial’s length are designed and spaced to improve the strength of the signal.

Generally, aerials are divided into two categories – indoor and outdoor. Indoor antennas are the types located on top of your tv set or next to it, while outdoor antennas are installed on top of your building and exposed to the elements. Most times, the type of aerial you’ll require will be determined by the location of your house. For fringe or rural areas which are far from the transmission stations and likely to be blocked by natural obstructions like trees and hills, outdoor antennas are more suitable.

The performance or effectiveness of your TV aerial can be affected by a couple of things. Firstly, it can be unaligned by poor weather which will affect the signal received and interfere with the picture quality of the TV. Secondly, the TV aerial cable can also become faulty or disconnected. This is mostly the case when you get a “no signal message on your TV screen.

Yes, an aerial could be installed in your garden or on outbuildings. This will depend on the strength of the signal in your area. A professional aerial installation company will be able to advise you on the possible locations for an aerial on your property.
