A digital receiver is part of a system of technology that includes digital satellite dishes, coaxial cables, and set top boxes. Digital television systems are readily available in today's marketplace, and the companies that supply them can frequently install the equipment for an additional charge. This can increase overall costs considerably.
Shoppers can look to online platforms to source the necessary purchases. When they enter the market place for a digital receiver, shoppers need to understand some of the fundamental principles behind installing a digital television system if they are to make a sound purchasing decision.
eBay provides a reliable platform for modern shoppers to locate satellite system components and any specialist tools required to complete the installation. eBay offers a large selection of items, which means shoppers armed with information can make sound purchasing decisions.
Installing a Satellite Dish
To display satellite TV programming, modern TVs must receive signals in a format that can be processed. Satellites transmit signals in very high frequencies that must be converted to the lower frequencies a TV processes. This is done using a low noise block-downconverter (LNB). An LNB is installed at the focal point of a satellite dish to collect the best possible signal.
Using an Existing Satellite Dish
Satellite dishes from previous subscription-based services are still useable. They can deliver a signal for a modern satellite service, and can provide a signal to support recording on other channels whilst watching a different one. Services of this type require two coaxial cables to function. Where two cables are not already installed, a second is required. The two signals cannot be provided by a signal splitter; they must both be provided by a twin LNB, which may mean the existing one must be replaced.
To replace a single LNB with a twin LNB involves a number of simple steps. Before removing the old LNB, users should find out what level of signal the dish is delivering. This information is important if you need to troubleshoot a replacement LNB that does not work properly. View the existing digital receiver setup screens and record the signal strength for future use. The final preparatory step is to find out at what angle the current LNB is fitted. A measuring device such as a protractor can be used, but a general "twenty to the hour" type observation is sufficient to start installation. Finally, since the new twin LNB may be heavier than the existing single LNB, all the mounting bolts on the dish should be re-tightened to prevent the dish from sagging due to additional weight.
The old LNB can then be removed. It may be connected with a rubber boot that keeps the LNB and cable in place. The boot must first be slid off. Alternatively, it may be held in place with a plastic channel over the arm, or by a spigot arrangement. This may require gentle tapping to free it. Fit the new LNB and secure it using the supplied fitting mechanism. Finally, the two coaxial cables can be attached to the LNB output posts and waterproofed with a combination of tape and silicone grease.
Using a New Satellite Dish
Setting up a new satellite dish is a routine service that many third party companies provide. Some shoppers may prefer to keep costs down by installing the dish themselves. A few simple tools such as a satellite meter can be useful to have if it proves difficult to find a strong satellite signal. Satellite meters can be readily purchased from online providers such as eBay.
The most important aspect of installation is to know the position of the satellite so that the dish can be mounted on the correct side of the building. Both Sky and Freesat services are transmitted by the Astra 28.E satellite. The satellite can be located in several ways. Dishpointer.com is a website that provides a useful tool to find the direction to point a dish. Users just need the name of the satellite and their postcode. The website then shows an aerial photograph with a line indicating the satellite's direction. You can also purchase apps for iPod, iPad, and Android devices. Perhaps the easiest way is to look around the neighbourhood and see in which direction other satellite dishes are pointing. Almost all satellite dishes receive Sky or Freesat signals, so this provides a good, general indication.
Once the direction of the satellite is determined, users should identify the best wall for mounting the satellite dish. This should be the wall that provides the clearest line of sight to the satellite. Drill a hole from the outside inward, angling the bit upward slightly to prevent rain from entering the building. Then attach the fixing brackets to the wall and check their position. They must be perpendicular; a spirit level is a useful tool to have to hand for this. Next, attach the satellite dish to the brackets and tighten any fixing screws and bolts until they are snug. Do not do not over-tighten, as the dish may need to be moved slightly to capture the strongest satellite signal. Finally, attach the two coaxial cables to the LNB.
Use a satellite meter to check signal strength. The position of the LNB should be adjusted to provide the strongest signal. All bolts and fixing screws must be tightened securely. Check the signal once more to ensure the the dish did not move during tightening.
Complete the installation by running the two coaxial cables to the television set
Installing a Digital Receiver
Connecting a digital receiver to a television set is a straightforward procedure. Each model may have minor variations, so installers should always follow manufacturers' instructions. Notwithstanding this, users can usually successfully install a receiver by following the steps below.
Scart Cable or HDMI Cable
The digital receiver connects to the television using either a scart socket or an HDMI cable. If the TV is HD ready and the receiver is also HD, it should be connected using an HDMI Cable. For standard definition services, the receiver should be connected using either of two scart sockets found at the back. It is preferable to connect using the socket labelled "TV". This is an active socket, which means that whenever the TV powers on it automatically selects the digital satellite mode rather than require manually selecting using the remote control.
The satellite dish should provide two coaxial cables, which can be connected to the two marked Vsockets, Input 1, and Input 2. If only one cable is available, it should be connected to the socket marked Input 1. This single cable delivers all channels with pause and rewind functions. Second and third programme recording functions are not present, as they are delivered through cable two.
Mains power from a suitable wall socket is delivered using the cable supplied with the digital receiver. First connect the three-pin plug to the wall socket and make sure the power switch is off when doing so. Then, attach the cable to the rear of the digital receiver in the appropriate socket and finally switch the power on at the wall socket.
Final Configuration and Activation
All digital satellite dishes require two final operations. The digital receiver must load the the latest version of its software and the digital receiver must be paired with the subscription card being used. Many satellite dishes download the latest software from the satellite dish but some manufacturers may require connection via a telephone line or via the internet using an Ethernet cable. Pairing a subscription card to the digital receiver will be done according to your service providers specific instruction but will probably require a call to an activation hotline.
Buying a Digital Receiver on eBay
Finding a digital receiver on eBay is a straightforward process. Simply head for the home page and type in "digital receiver" in the search bar. eBay then returns a list of digital Freeview boxes for you to examine in more detail.
Each item listed by eBay comes with a description in which the seller should provide all of the information you need to make a decision about purchasing. In addition to the item description, you should be able to find answers to other questions you may have about the item. How much postage costs and available delivery methods are both usually detailed as part of a listing.
Clicking on the seller's name reveals details of all of the feedback they have received from previous buyers. You can see seller and buyer feedback if you wish, as well as details of other items they currently have listed on eBay. These features mean you can enter into the marketplace with confidence in both the product and the seller.
Acquiring a digital receiver to view satellite television is a simple first step that can lead to further electronic do-it-yourself experiences. Making purchases with electronic do-it-yourself in mind can also lead to considerable savings on installation costs. Simple explanations of the steps required and an inventory of useful tools is often all one needs for a successful installation. eBay is an ideal online destination when looking for such tools and equipment.
To make an informed technical purchase, buyers can use one or more of eBay's helpful tools that make things easy for the do-it-yourself shopper. Detailed descriptions of technical items should be available in each item's description. If the information provided is not enough, then buyers can ask questions of the seller directly. The eBay message system is simple to use; all one must do is type in a query, and it is sent directly to the seller for their response. Buyer can also find out more information about a specific seller. Looking at their feedback profile gives one clear idea about how the seller has fared with sales of this type in the past. Both of these eBay tools mean that even buyers new to do-it-yourself electronics can make an easy decision about purchasing online.
