Where is the lnb sky

Standard dishes are sold all over the world. They are built to the lowest possible price. All Offset dishes are oval - not circular. A standard offset dish is usually higher than it is wide. A Sky mini offset dish is wider than it is high. A standard dish uses a 40mm universal LNB. This LNB has a 40mm neck. The dish uses a saddle clamp to clamp the 40mm neck of the LNB into the 40mm clamp.

Either way it fits onto the arm and not in a saddle clamp. It is possible to buy a standard LNB and attach a Sky mini dish adapter see bottom picture above so that a standard LNB will then fit on a Sky mini dish, however, the feedhorn is not an ideal match as the standard LNB is designed to collect signal from a dish that is higher than it is wide.

If the customer intends to upgrade to a better standard dish in the future and needs a new LNB now.

Quatro LNBs are designed to work with multiswitches Also note that we do sell a special multiswitch that will work with a quad LNB and so a Sky mini dish can therefore be used with a multiswitch. This is ideal when a mini dish is already installed, and has a quad LNB fitted to it and is very inaccessible so difficult to change. Since multiswitches are professional products, it is, however, best to fit a higher quality standard dish with 40mm quatro LNB if possible.

Sky quad LNBs can be fitted to a standard dish. If the Sky adapter collar is removed, then a small piece of plastic that stops the collar from rotating is cut off with a craft knife, this will leave a 40mm neck and the LNB will then fit a standard dish.

Problems with Sky mini dishes. As a general rule they do not provide enough signal in poor weather locations. Maybe that is why hardly a day goes past without a call from a customer complaining of lack of signal, pixilation, freezing and drop-out even on good days and asking for a better solution. Standard dishes fit a vertical pole of a standard wall mount and the LNB is held by a 40mm clamp.

This allows higher quality standard 40mm LNBs to be used. Standard dishes have been sold worldwide since satellite started in the UK in Non-standard Sky mini dishes started around and Sky have changed the design of their dish at least 10 times. They use a non-standard wall mount and LNB fitting particular only to Sky mini dishes. High quality standard LNBs from countless manufacturers cannot be used. Twin and quatro LNBs cannot be fitted to Sky mini dishes.

Sky don't make them. Customers with early Sky dishes can no longer buy the different non-standard early Sky mini dish LNBs for their dish and are forced to change the whole dish when an LNB fails. This is because the latest Sky mini dishes have changed yet again and the latest Sky mini dish LNBs no longer fit earlier dishes.

The earlier types of Sky mini dish LNB are no longer available. The same is true of spare parts. A standard 40mm clamp LNB will fit a standard dish from when satellite started. The same is largely true of standard wall mounts. The only real advantage of a Sky mini dish is it tends to be cheaper than a standard dish. Sky mini dishes are prone to severe rusting in high salt areas but the heavy duty standard range below is designed for that type of location. For all of the reasons detailed above we would recommend customers use a standard dish for Sky, freesat or any other satellite reception application.

Examples of standard dishes - Primesat Easy Fit high quality 60cm dishes. Primesat Easy Fit high quality 85cm dishes. Primesat clear transparent standard 85cm dishes. Triax Heavy duty standard 60cm, 70cm and 90cm dishes for high wind and high salt areas. For all-weather capability in the north e. What is an LNB? An LNB is the box of electronics on the end of the dish boom arm. It acts like a aerial masthead amplifier. The signal microwaves reflect off the dish and into the feedhorn to the LNB.

Here it is amplified and the frequency is lowered. The lower the noise figure the better. The signal is then sent down the coaxial cable to the satellite receiver. Quality digital cable should be used.

Single have one output, twin - two outputs, quad - 4 outputs and Octo - 8 outputs. All outputs are the same and are equivalent to a single LNB. A twin LNB could be used for two single tuner satellite receivers or a twin tuner satellite receiver Quatro LNBs have 4 outputs and they are all different. Quatro LNBs can only be used with multiswitches. This refers to the way they fit on a dish.

A 40mm LNB has an integral offset feedhorn and fits to the most common types of offset dishes. C flange LNBs fit on a separate feedhorn and could be used on either offset or prime focus dishes. They are usually used on specialist high quality dishes. Both 40mm and C LNBs could have single, twin, quad or quatro outputs.

At the moment only 40mm LNBs have octo outputs. Using a quatro LNB and a multiswitch it is possible to have many more outputs. Even 32 outputs or larger. A Sky mini dish LNB uses a fixing that is none standard and a tongue fits into the end of the boom arm To find out more about LNBs and how the perform see below. Is there much difference between the efficiency of different makes and types of dish?

AND, How can I get more signal from my dish? Would a better LNB help or a more sensitive receiver? AND, Problems with signal through trees. Answers - Dish size is everything. Dish size is everything. LNBs only have a very very very very Dish size is everything!

Going from a 0. Bigger dishes provide more signal in all weathers. To achieve 0. Simply not possible at normal temperatures in the UK.

It may well be the case that the new 0. They are very good LNBs. Possibly even be the best, but they really can't be as low as 0. Some of us are getting old! We all now know that what was really needed was a decent sized aerial on the roof and preferably not in the loft - which can produce reflections!

Many people would like technology without wires in sealed boxes like my wife, she will insist on having the stuff in cabinets with doors on. This is better known as an cooking the technology in an oven as it stops ventilation and creates a fire risks. Many also want the smallest possible dish so the question is - "find an alternative solution to getting more signal" BUT To repeat - Dish size is everything!

Dish efficiency. This can be important. Especially among large dishes. Fibreglass Ladders. Podium Ladders Step Ladders. Packing Supplies. Electric Cables. Power Supplies. Wall Plates. Electrical Trunking.

The latter meaning that if you need to make sure that the cables that feed each satellite receiver corroborate with the connections on the LNB otherwise it will not work. There is not switching on the LNB again, it instead looks for the frequency of the transponder for the channel that the satellite receiver has requested and oscillates it to the lowest available frequency.

For this reason, a new approach must be adopted, and this is done via a Quattro LNB and multi-switch amplifiers. It must be connected to a multi-switch amplifier with separate VL, VH, HL and HH inputs where the switching instead takes place and the cables must not be mixed from the LNB and the input of the amplifier. By using this concept only four cables need to be installed between the satellite dish and multi-switch amplifier concept can be extended to serve hundreds of satellite TV points.

Just remember that you will need four separate splitters or a splitter with four separate inputs. A Monoblock LNB designed for use with 80cm satellite dishes or larger for signal reception. As satellite signals are beamed down to earth is very low strength one of the main roles of the LNB is amplify the signal. I certainly do not have the time to speak on the phone and I do not give out my mobile phone telephone number as is regularly requested.

That being said, I respond to blog comments as this gives me a central location to deal with all the questions and everyone reading the blog gets the benefit of the question asked and the answer given.
