Satellite Dish Not Working And How To Fix Satellite Dish Signal

Preparing to watch the greatest two finals in this summer, Later you realized that satellite TV is not working. This is embarrassing, Don’t worry this post will guide you to analyzes the reasons that could be arise why your satellite dish not working and how to fix satellite dish signal problem. Let’s examine them one after the others

Reasons Why Your Satellite Dish Not Working And How To Fix It

No Signal On Satellite Dish

To get maximum signal level, Then your satellite dish needs to be aligned correctly to avoid loss of signal, It is not proper to align a satellite dish by eyesight alone or by mere looking at the others house’s satellite dish. simply because of the way they work and the transponders/frequencies that they use. There’s a big differences between a signal with good quality signal and no signal at all. Increase or little adjustment to realign your satellite dish already knocked off direction could be the reason why your satellite TV not working and this is how to fix satellite dish.

You need to understand and keep in mind the following, The elevation and the screw, The east and the west, The adjustment on the LNB itself. For instances, Beoutq and Sky both faces East and this explain deviation off due south. due to the fact that it is beaming the signals down to the earth from an angle. Adjustment must be made on the satellite dish to make rooms for this. And the LNB itself explain the phenomena of vertical and horizontal polarized signals. Anyway here are some tutorials on watch European and US TV.

Suppose you want to try it by yourself, It is highly recommend to use signal finder or TV Spectrum analyzer as you can watch everything on the screen when the high quality signal is achieved. Surely, Not everybody owns or have access to satellite alignment tools. It can be purchased via online or local shops. Make sure you have idea of what direction you are pointing the dish as important.

How To Determine The Location Where Dish To Face

To determine where to point your dish, then you need to satellite co-ordinates like dishpointer for easy installation, You just need to enter your postcode and the satellite you wish to install or use, And it will give you all the information on both east and west alignment angle, the elevation and the screw adjustment. It will help you with indication of line of signal for you to use as a reference.

I strongly recommend using compass and inclinometer while making attempt to aligning your satellite dish. Don’t forget to consider the allowances differences differences due south and magnetic south usually change.

Weathering/Waterlogged Cables

Due to the facts that satellite dishes needs to be install outside and because LNB requires satellite receiver to work together as a unit. It is good to cover all the connection made to the coaxial and the LNB itself. To avoid loss of signal, There should be adequate weatherproofing measures put in place to prevent any rainwater onto the inside of the cable. Here are the common ways to prevent weatherproofing or waterlogged.

A. It is very easy for water to get inside the coaxial cables if the weatherproofing cover on the LNB is pulled down, Most especially when you are in seaside or coastal region, You have to ensure that the cover on the LNB is well placed down.

B. The F-connector is expensive and requires specific tools to put them onto the cable for tight connection. One need to use weatherproof F connectors.

C. Ensure that silicone grease are pour on the top of weatherproof plugs and other connections joint. I strong recommend it for satellite engineer in order to keep the outside of the plugs in perfect order.

D. Ensure that you put amalgamating tape to the top joins and to ensure a good weatherproof. Suppose your satellite signal is not working and you realized that the connectors themselves are waterlogged. cut off the affected part to make another cable connectors. If you see that the inside of the cable has rust, wet and partial contact, It will be good replace the whole of the cable.

Satellite dish Obstruction

Obstructions Or Trees Blocking The Satellite Signal

Obstructions could be a barrier, For Instances Trees, Storey buildings, Mass Communication Antenna and others can block your satellite dish installed nearby this obstructions. It can affect your signal if placed above the Satellite dish.

For your satellite dish to work perfectly, You need clear the obstructed trees, or move your dish itself higher than the trees. You can move the dish away from the obstructed buildings or trees. In any circumstances, A good satellite dish installer or technician needs to consider the location where dish would be mounted. And free from obstructions And this is one the way on how to fix satellite dish signal problems.

The following are the temporary obstruction of satellite dish:

  • A nearby Scaffold
  • Cobweb spread either on the dish or inner side of the LNB

The best solution to this problem, You need to clear and clean the particles made by the spiders or any other insects. Also by removing the scaffolds nearness to your satellite dish.

Faulty LNB

It is very much possible that the LNB itself has become faulty and caused lost of signals. This is similar to any others electrical devices that can just develop a fault for unceremonious reasons. Satellite TV signals might be working fine for so long and suddenly fail. Faulty LNB’s can be liable and responsible for it.

There are some LNB’s that develop fault and still appear as if it doesn’t faulty. It can be very much difficult to diagnosing these type of faults. even if you own or borrow high performance test tools as you often check the satellite signals and realized that everything is in order.

If your satellite dish is well aligned and accurate with no obstructions blocking the signal with no significant weathering disorder and during the night seems not to be cloudy when properly checked.

I would strongly advice that the LNB should be replaced. For instance, It happened to me one day while re-aligning the client dstv dish, I worked lengthy, signal seems to be ok on my sat meter but when i try to test the signal on dstv decoder it fail to scan the channels, Later I suggest remove the LNB and test it again. then dstv is able to scan and everything is perfect.

Having said that faulty LNB’s can also be responsible for you lost signal on your dish and it is not easy to diagnose in certain situation than to replace the faulty LNB. And this is how to fix satellite dish signal problems.

Electrical Storms Thunder, And Heavy Rain

Satellite signal reflected back to the earth surface from the satellite in space. Atmospherics and weather conditions can also affect your satellite TV reception. Most importantly cloud rather, electrical storms and heavy rain. The radio wave is an electrical conductor. Radio waves can pass through through conductor, rain and storms. This can also cause why your satellite dish not working.

Certainly, the signal usually comes back after the rain beacuse the storms eases the signal. If you often lost signal when there’s little rainfall. Then I will recommend you to try any larger satellite dish to increase the signal quality in small amount.

As far as thunder is concern, This usually happened in Africa, As it is caused by lightening and thunder. It is not possible for thunder to strike without lightening first. whenever there’s lightening, It makes the way for thunder to strike and enter through LNB and later to any connected devices. It caused damage to the LNB either you are watching during the rain or power off. That’s why your satellite dish not working after raining. I will recommend you to disconnect any home appliances connected to the satellite dish or from the wall socket.

Why Satellite dish signal not wrking

Poorly Disconnected Cables

This often occurs as a result of short cable connection between the LNB or receiver. There’s chance for negative charges of the coaxial cable to touch the positive conductor. This would cause the flow of direct current (DC) flowing up to the LNB from the Satellite receiver. This can also cause hardware problem to receiver and leads to total loss of signal.

Other common problem involves poorly disconnected cables includes:

  • Centre conductor is too short and there’s partial connection
  • Plug completely loss the connection
  • Incorrect size of the plug for the cable

To fix satellite dish signal problems in this situation, You have to use enough coaxial cable without any joined. Ensure tight connect between the cable and F-connector and make sure you use original cable satellite TV dish.

Broken Satellite Dish

Since satellite signals are beamed down to earth from satellites in space. It later reflected by the bit round or oval part of the satellite dish antenna through the LNB. If any part of the satellite dish is bent or completely rusty. This can cause the satellite signals to lost any part of the dish. The LNB would not be able to catch any signal

Similarly, If the LNB sit or holder is slightly faulty and can’t hold the LNB perfectly. This could result to the reason why you satellite dish not working. It is advisable to replace the damaged LNB hloder.

External Electrical Interference Generated From RF/EMI

This often occurs under faulty conditions and should be reported to whomever behind the scene for though checking happens in your environment. Many phones operators or Network providers that use frequencies with the satellite intermediate frequency band (IF). However, Once in a while, there’s chance for your satellite TV reception to get affected. And you may need to relocate your satellite dish. I will recommend to change or replace the LNB with a inbuilt LTE filter components.

Others satellite dish signal problems includes high gained signal. This is rare situation, If the coaxial cable is connected to high gained LNB, there’s chance for you to experience loss of signal. So you have to use a signal attenuator to convert the DC to the normal one that satellite TV uses.

Avoid using more than one joint, Because if the joint is more than one. Then there’s chance to loose signal on your satellite TV. These are the reasons why your satellite dish not working and how to fix satellite dish signal problems.
