Twin Satellite Shotgun Coax Cable for Sky Q, Sky HD, Sky+ and Freesat - Black

Product Information

If the LNB is a Sky Q only type then that won't work with other kit, such as a Freesat box or a TV with built in satellite tuner. You would need a Hybrid type that works with both or a "legacy" LNB that works with Freesat/TVs but not Sky Q. As you can see from this article, that this is a difficult question to answer as there are multiple factors that effect how far you can send a TV signal down a coax cable. This includes quality of the cable, size of the centre conductor, the frequency that you wish to send down the cable, whether amplification will be introduced or not. If you were sending the signals down a 100m cable with a 2dB loss per 10 metres of the frequency you’re carrying, then if you send it down 100m of cable you will get 20dB loss. This shouldn’t be a problem if you’re getting 75dB off of your TV aerial, but if you’re not in a good signal area and get less than 60dB then the cable length will be a problem and amplification will need to be introduced – or a cable with a larger cross sectional area of the centre conductor. One way of getting the cable cost down is to reduce the amount of copper inside the cable. This is where Copper Clad Steel & Copper Clad Aluminium cables come in. Although you save money, you lose out considerably in terms of performance so I would opt for all copper conductors instead if the budget allows it. The steel conductor in CCS is prone to rusting over time and the steel conductor doesn’t have it very good current carrying capacity. As there is a considerable voltage drop with cables lengths exceeding 30m using a CCS cable for satellite LNB connections is not a good idea as the voltage drop could cause issues with the LNB switching.

I would however be very wary of called branded or marketed as “RG6” as the modern equivalent is far inferior in terms of performance. It is cheap to buy which is why some people use it. It has a solid copper clad steel centre conductor with a foam filled dielectric and aluminium. The massive 2 TB storage capacity enables you to watch one channel, whilst recording another. Additionally with multi-screen you don’t have to worry about drilling extra holes because with Wi-Fi you can stream HD video from your main box. Coaxial cable works by carrying data in the centre conductor, while the surrounding layers of shielding stop any signal loss (also called attenuation loss) and help reduce EMI. Cables with 75 Ohm are mostly used for video signals, while 50 Ohm cables tend to be used for data and wireless communications. Webro WF100 is the cable I use for all of Smart Aerials TV aerial installations. Although I will occasionally use a shotgun cable for satellite over short distances Webro WF100 is undoubtedly the preferred option. WF100 is a foam filled coaxial cable with all copper conductors, so solid copper centre conductor, copper braid and copper shield. Webro HD100 technically is a better cable with its extra cable screen but in my opinion, it isn’t worth the extra expense.A braided mesh made from copper then helps to shield the cable from electromagnetic interference (EMI) If you’re going to be installing lots of internal coaxial cabling you should install LSZH coaxial cabling. LSZH stands for Low Smoke Zero Halogen which means in the event of fire the toxic fumes given off from this type of cable is far less than other types of coaxial cabling intended for outside use. As the fibre optic signal is virtually loss-less, with the right equipment you can send TV Aerial/ satellite signals over kilometres! The equipment required for terminating fibre optic cabling can be expensive but you can buy pre-terminated fibre optic cables which just plug in, I recommend erring on the side of caution and buying pre-terminated fibre slightly longer than you think you need as you don’t want to come up short. The excess can simple be coiled at either end. For your reference most fibre equipment for TV systems using single-mode fibre and FC/ PC connections.

Every piece of TV aerial/ satellite equipment will have a maximum signal strength that it can handle and the signal level in your system should never be allowed to go beyond this as this could overload your equipment and cause poor TV reception, including loss of signal and pixelation. It could even damage the parts/ components of the equipment. If you need to amplify the signals to very high levels like is the case for communal TV systems, you will need a professional launch amplifier to do this which can carry a high signal strength through it.If the previous occupant had Sky Q and the dish/LNB are still in situ is the LNB a Sky Q only one or a Hybrid? I plan to move the Sky+HD box and it’s flatscreen telly to the other side of the house so need to extend it’s ‘shotgun’ cable to reach. The most common reason that I use compression plugs is for the larger type coax cables that are only commonly used on communal TV systems to help reduce signal losses over long distances. You don’t want to be installing a screw on F plug on anything more than a conventional 1mm coax cable and crimp on F plugs can be really difficult to insert on the 165 coax cable and above so I just compression plugs of these as they are actually the easiest to install, providing that you have the correct equipment that is. You will want to be very careful as the plugs can be very expensive for the larger cables so you won’t want to mess many connections up. There is actually a triple screened coaxial cable on the market called HD100. The extra screen is on top of the cable braid. Although the performance on this cable is superior, I personally think that this is overkill and not worth the extra expense. I’m not the only one as the popularity of this cable type hasn’t really caught on.

In coaxial cables, Ohm refers to the impedance, which is the measure of resistance in the cable to the flow of electrical energy. What’s RF coaxial cable? A common cable in domestic settings, RG-59 cable is similar to the RG-6, but it has an even thinner centre conductor. This makes it a good choice for short runs and low-frequency transmissions. What’s RG-11 cable? To select the dSCR settings that will allow a compatible LNB or multi-switch amplifier please follow this process. The F plug came from the USA and is most commonly used for satellite dish connections at both the satellite LNB and the satellite receiver itself. The F plug has a threaded connection that allows the plug to be screwed in securely and not fall out of position which can be common with over types of coax plugs. F plugs are also now very common for TV aerial and communal TV systems for connections at aerials, splitters, amplifiers and for joining coax cable.You want to install your amplifier in a location where the signal is still of an acceptable strength, before cable losses have taken effect. For conventional TV Aerial systems the best place to amplify a signal is up near the antenna usually using a masthead amplifier which can also be powered off the same connecting coax cable that provides the signal. You do not want to introduce an amplifier after the resistance from the cable length has caused to drop the signal too low, as the amplifier would be trying to boost something that is not there. When you see the terms SDU and MDU, these stand for Single Dwelling Unit and Multiple Dwelling Unit meaning domestic and communal basically. This means that cable that is certified for “MDU” use is suitable for both domestic and communal installations but not the other way around.

In reality “shotgun” cables will only be used for domestic environments and relatively short cable distances and WF165 cable will only normally be used on large communal satellite TV systems with very long cables lengths but you get the idea. We also include wall mounting clips to facilitate connecting the Sky cable to a wall. Why Choose Our Sky Extension Cables? There are lots of different coaxial cable sizes, below we discuss the most common types used for Sky, Freeview, Freesat and communal TV systems. There are a few things that define what cable size will be used but this mostly has to do with cable length when installed. The smaller the cable size the greater the signal losses over distance. The number before the cable type represents the centre conductor size. The next cable size above is 165 coaxial cable. I’m sure you know where I’m going from here so I’m not going to list anymore coaxial cable sizes, although there are more. The reason being when you get higher it would be more suitable to install fibre optic cabling instead. 1.65mm cable is pretty much used exclusively in communal TV system and CATV systems. It has a signal loss of around 2dB at the highest frequency. With cables this size and above it can even be difficult to get crimp on plugs to fit well so I would advise installing compression plugs instead.NatWest, RBS and Ulster Bank to close at least 172 branches in 2023/24 – here's the full list, plus alternatives When installing a coaxial cable, it is imperative at that the centre conductor and the cable braid and centre never touch, even one single strand of the cable braid touching the centre conductor will create a cable short and could result in loss of TV signal altogether. This definitely will happen where line power is present which could be powering your satellite dish, amplifiers and magic eyes. As the dielectric inside a coax cable is to primarily stop the conductors touching this must made from a non-conductive substance with insulating properties. This is most commonly a foam filled substance,but some coax cable types use a PVC/ air where the PVC keeps an air separation.The dielectric also helps define the impedance of the coaxial cable, so it is also carefully keeping the correct distance between conductors. For this reason,it is important not to squash the cable at terminations or kink the cable when installing it. There are many types for F plugs for different size coaxial cables and plugs that terminate differently like screw on F plugs, crimp on and compression plugs but in essence they are very similar. If you’re planning you own TV aerial or satellite dish installation and require a particularly long length of coax cabling between your antenna and your TV, or if you want to connect your outbuilding/ shed etc., which may be some distance away with a reliable TV signal, read this article for all you need to know. In this blog I discuss maximum lengths of coax cables, signal losses and how to overcome these with things such as amplification. Without any further ado, let’s begin.
