However, rain isn’t the sole problem. Snow, ice, strong winds, and dense fog can all disrupt satellite reception.
Is the weather a factor in the satellite signal?
Microwave radio waves move in straight lines and cannot pass through solid objects, therefore satellite Internet connections use them. The air between the dish and the satellite is affected by the weather, and moisture decreases the signal. Because the stronger the received signal, the more resistant it is to rain or snow, weather has a greater impact on lesser systems. Wind can also inflict physical harm.
Is weather a factor in Dish TV?
Yes, inclement weather such as strong winds, heavy rain, and heavy snow can disrupt satellite TV services, but the good news is that this is quite unusual. The majority of people will never face such a challenge. As a result, this problem should not prevent you from taking use of all the benefits offered by companies like DISH and DirecTV.
What causes satellite dishes to lose their signal?
This problem is frequently caused by a slightly off-kilter satellite dish, broken or malfunctioning equipment, bad weather, or something blocking the dish’s view of the sky. Your signal strength may limit the delivery of live programs, but you can still watch recorded content if you have a DVR.
What is causing my satellite signal to be disrupted?
If your satellite picture freezes, pixelates, or loses sound, it’s most likely because the dish has moved, the cable has been damaged, something is in front of the dish, it’s raining heavily, or there’s snow in the dish.
When the weather is terrible, why does my TV lose signal?
There are few things more aggravating than settling down to watch your favorite show only to have a poor or no signal message appear on the screen, which may be followed by blocky images and pixelation, and then looking outside to discover that it is pouring. You might be asking why my satellite/sky signal goes out when it rains. What can I do to put a stop to it? In this article, I’ll explain why this happens and offer some suggestions for how to prevent it from happening in the future, or at the very least drastically minimize it. Let’s get started.
Rain Fade Explained
Rain-fade is the term for the harmful effect rain has on satellite transmissions. The absorption of a radio/ microwave signal by atmospheric circumstances such as rain, ice, and snow is referred to as this. Because satellite and Sky TV signals travel through space, they must pass through this before reaching your satellite dish, which then feeds your satellite receiver, which must be operating at an adequate level for reliable reception. The larger the volume or intensity of rain, the greater the effect of the rain-fade; as a result, the signal received by the satellite dish may drop below the recommended minimums, resulting in poor reception. Furthermore, the greater the signal’s sensitivity to rain, the higher the frequency. Satellite TV, which operates at very high frequencies with very short wavelengths in the Ku Band (10.7-12.75GHz), is more affected by rain than terrestrial TV, which operates at a considerably lower frequency. This effect is amplified even more by services like satellite broadband, which operate at higher frequencies while remaining inside the Ka band.
How To Improve Satellite Signal in Rain, Remove Rain Fade
I offer some tips in this part for removing rain-fade from your satellite signal. I’m sure you got it by now, but the better the satellite signal reliability/ ruggedness is typically defined as Carrier to Noise Ratio (C/N) or Modulation Error Ration (MER), the less likely your TV will fail in the rain. The Cliff Effect is a term used in the industry to describe the point at which a digital TV picture breaks. The visual quality does not decline gently like it did in the old analogue days, whether if you are securely on the cliff edge or off it. As installers, it is our responsibility to get as far away from the cliff edge as possible so that you do not fall off.
Strength – 52 dB, MER – 10 dB are the recommended minimum readings for reliable satellite TV reception.
Align Satellite Dish For Peak Reception
I have already written a prior blog on how to position a satellite dish, which you should read after you finish reading this one. You may discover that, although having a satellite signal that works the majority of the time, the dish is slightly offline, and that the alignment can be adjusted to improve the situation. This could be because it was never correctly oriented when installed or because it has drifted somewhat due to severe winds, especially if the dish is old and rusted. Without the proper equipment, this is a difficult operation, therefore you may need the help of a satellite expert with a good TV spectrum analyzer or alignment tool; even some of the less expensive satellite alignment tools are difficult to use when aligning a dish for peak reception. If you opt to do this yourself, you may discover that you have some signal readings in the settings of your satellite TV or receiver that you can try to enhance while playing around with your satellite dish alignment. Some provide information on Bit Error Rates and MER readings. The satellite signal strength/quality is displayed on Sky boxes, but it should only be used as a reference and isn’t particularly useful.
Dont forget the Skew Adjustment!
This is frequently ignored, even by those in the industry. The angle at which the LNB rests within its holder is known as the Skew adjustment. This must be correctly configured in order for the dish to distinguish between horizontally and vertically polarized transmissions. Because satellite television satellites are in geostationary orbit and revolve around the equator, an arc in the sky would develop if you could see all of the different satellites in their orbital positions when facing south in the northern hemisphere or north in the southern hemisphere. The highest point is straight south (northern hemisphere) and the lower this is the further east or west you depart. If you can image the effect this would have on satellite signal polarizations, they would gradually get more diagonal the further you got away from due south, and you’d have to tweak the LNB to achieve the best signal quality. If this is adjusted incorrectly, it might have a significant impact on your reception. A skew setting of -13.4 would be required for the Astra 2 satellites, which are located at 28.2E and beam Sky and Freesat signals to the UK, using Dishpointer.
Upgrade The LNB
If you replace your satellite LNB with a higher-quality model, your satellite signal may improve, reducing the effect of rain-fade. If you have a short cable run, the gain of the LNB isn’t as critical, but you should opt for an LNB with the lowest Noise Figure available. This is the amount of electrical noise that the LNB introduces into the signal; the higher the quantity, the lower your C/N and MER readings will be. With a new LNB, you may notice that your satellite/ Sky TV signal fails a lot less in the rain than with an older device with high noise statistics.
Install A Larger Dish
I’m sure you’ll agree that the bigger the dish, the more signals will be reflected to your LNB, resulting in a stronger and more consistent signal. What size satellite dish you need depends on the satellites and countries TV you want to receive, as well as where you want to receive it. I have already written an article on what size satellite dish do you need which may help you, within this I suggest the minimum suggested dish sizes for the receptive satellites in the north and south UK, but just because it is a suggested minimum doesnt mean its a bad idea to install a larger dish. A larger satellite dish may not make you popular with the wife, but it can assist boost your satellite signal in the rain. For example in the South of the UK a Zone 1 43cm mini-dish would normally offer reliable reception for Sky and Freesat TV, but on occasion when customers request a larger dish to improve the signal quality, I install 60cm Zone 2 satellite dish which normally only would be installed North UK and Scotland.
It Might Be Water Penetration On The Coax!
Obviously, the natural reaction to losing satellite signal during severe rain and thunderstorms is to think that rain-fade is at blame, but this could be a red herring. It’s possible that water has penetrated the coax connection connecting your LNB and satellite receiver, causing a cable short, preventing DC voltage from passing from the satellite reception to your LNB, resulting in no satellite signal. The most typical cause is that the LNB rainwater cover has not been drawn down to protect the F connections, or the wires have not been properly weatherproofed. You’ll need to bring down the rainwater where you have an LNB with one, and you might want to use a smear of silicone oil around the connection, a wrap of self-amalgamating tape (which is difficult to get around several connectors), or waterproof F connectors.
No Installer Can Guarantee a 100% Signal All The Time
There are simply too many factors that may go wrong and affect a satellite signal, even if everything has been installed correctly, for any installer in the world to promise that you will always have a reliable signal. If you signal is only go off in torrential rain or lighting storms there is a chance that very little can be done to improve things, short of putting a ginormous satellite dish up which may require planning permission. If, on the other hand, your satellite signal drops at the first indication of rain or cloud cover, you know things can be better, and you can try the strategies mentioned above.
Get a TV Aerial/ Stream TV Instead
If you don’t have a Sky subscription or another satellite TV service, you might want to consider installing a TV aerial and watching live TV through it instead. Although TV aerials/ antennas are not immune to the effects of rain on the signal, they operate at a much lower frequency, which is less impacted by rain, and they receive their signals from land-based transmitters rather than satellites in orbit, thus rain has less impact on reception. Freeview is the name given to free television received via a television aerial in the United Kingdom; Soarview is the name given to free television received via a television aerial in Ireland, and both have a large number of TV channels and HD content. For live TV, some subscription-based services, such as BT Vision, need a TV aerial.
You might also get your TV service through here, as the internet is transforming our viewing habits. If you want Sky services, you could subscribe to Now TV, or if you just want regular terrestrial TV, you could subscribe to Britbox instead. It wasn’t long ago that terms like TV on demand, streaming content, and IPTV were unheard of, but now we have a plethora of options to choose from. There are far too many to list here, so I recommend doing some research on what you want to receive.

When it rains, why do I lose TV channels?
Atmospheric circumstances, such as high air pressure (which gives nice weather), severe rain, or snow, can impact TV and radio broadcasts, both analogue and digital. This may result in temporary pixelation or viewers receiving signals from outside their viewing area on Freeview (or even from other countries).
How can I keep my satellite dish safe from the wind?
- Relocate your dish to a drier position if it is located under trees or on the eave of a home where water from the trees or roof falls on it.
- If the dish is installed to the side of a home, a clear piece of fiberglass can be placed in front of it. Water doesn’t impact the dish’s capacity to receive a signal because the fiberglass acts as a shield.
- Spray a nonstick cooking spray on your satellite dish. Raindrops are prevented from adhering to the dish, causing it to receive signals incorrectly. Spray the dish at least once every three months, depending on how frequently it rains in your area.
- The dish may be out of line with the satellite if the rain is accompanied by strong gusts. When the dish is installed on a tall pole, this is more likely to happen. Although you may be able to perform the adjustment on your own, you may be better off hiring a professional.
Is satellite Internet affected by poor weather?
Because data must travel through the air, satellite internet is more prone than other types of internet to experience connectivity troubles during inclement weather (rather than through wires buried underground). You can see a line moving from your house to a satellite thousands of miles away, then back to Earth to a ground station if you trace the journey the data takes. The signal then reverses direction and returns to you in the same manner. Bad weather can weaken, block, or deflect the satellite signal throughout this travel.
Satellite signals are sent using radio waves, which travel best in wide space but can be deflected or dispersed when passing through water, buildings, or dense vegetation. This is why satellite communications deteriorate in bad weather like rain, snow, and even dust storms. The radio signal is deflected and broken up by water or dust particles in the air, resulting in a patchy or weak signal.
Because water in its liquid form is the densest, raindrops have the most impact on radio waves (and most difficult for radio waves to travel through).
12 Fog, snow, and even hot, humid weather, on the other hand, might disrupt or decrease your signal. Because trees and leaves contain a lot of moisture, they can obstruct or reduce satellite signals.
Because satellite internet equipment is placed outdoors, it is also susceptible to outages during inclement weather. Satellite dishes can be destroyed during extreme weather events such as hurricanes, floods, or tornadoes, which can damage the equipment or force it out of alignment, despite being very weather resistant to most types of storms.
What factors influence the quality of satellite signals?
Loss of signal level is frequently caused by problems with your transmission line, which should be investigated first:
- Cable that is broken or kinked – Visually inspect the whole length of the coaxial cable that connects the antenna to your indoor modem. Look for kinks in the sheath, as well as broken or loose connectors. Replace your damaged cable with a new one.
- Center pins that are broken, rusted, or deformed Visually inspect the center pins on each connector. Not only the cable, but also the modem, LNB, and BUC connectors. Also, ensure sure the shielding on the connector is correctly ended and that no stray wires are shorting against the center pin. Replace any connectors that are damaged.
Why is my television now reporting that there is no signal?
- If your television is connected to a cable or satellite box, you may need to contact your service provider for additional help with signal strength.
- If you have an over-the-air antenna on your TV, you may need to tweak it to increase the signal quality.
- Try rescanning for active channels if your TV is using the built-in tuner with direct cable or an over-the-air antenna. If you’re utilizing a cable box or satellite receiver, you can skip this step.
