How to Check Your Satellite Dish Aim After a Storm
A severe storm can shift a satellite dish by only a few millimetres and still cause pixelation, audio dropouts, or a complete loss of signal. Strong wind, hail, falling branches and water entering outdoor connectors can all create similar symptoms, so checking the pointing angle is an important part of troubleshooting.
SatPointer gives you a practical way to compare the dish’s current position with the calculated direction from your property. By using your location, Google Maps and satellite orbital data, it can show the azimuth, elevation and other alignment details needed to inspect a dish safely and methodically.
| What you notice | Likely cause | First check |
|---|---|---|
| Picture breaks up during rain only | Rain fade or marginal signal | Check alignment, cable condition and dish size |
| No signal after high winds | Dish movement or damaged LNB | Inspect the mount, bracket and LNB arm |
| Signal strength is present but quality is poor | Slightly incorrect aim or interference | Recheck azimuth, elevation and skew |
| One service works while another fails | Transponder, beam or polarisation issue | Confirm the selected satellite and LNB settings |
| Dish appears straight but reception is absent | Water in connectors or damaged coaxial cable | Isolate and inspect every outdoor connection |
Start with a safe visual inspection
Do not climb onto a wet roof or handle a dish during lightning, strong wind or unstable conditions. In many Australian homes, dishes are fixed to tiled roofs, metal roofs, poles or wall brackets, and each mounting arrangement presents different risks. A ladder on a slippery verandah or corrugated roof can be more dangerous than the alignment problem itself.
From ground level, look for a dish that is leaning differently from its usual position. Check whether the mast is still vertical, the bracket is tight against the wall or pole, and the dish has been pushed sideways. In cyclone-prone parts of Queensland and the Northern Territory, gusts can twist a mount without leaving obvious damage. A bent LNB arm, cracked reflector or loose feed clamp also deserves attention.
Water is another common post-storm culprit. Examine the coaxial connector at the LNB, the cable loop below it and any joins near the wall entry point. Damaged weather boots, split insulation and loose F-connectors can allow moisture into the cable. If the dish has moved, record its approximate position before touching anything; that gives you a useful reference while comparing it with SatPointer.
Select the correct location and satellite
Open SatPointer and set the installation location as accurately as possible. Search for your address or place the map marker directly over the property. This matters across Australia because a few kilometres of location difference usually has little effect, but selecting the wrong town, state or side of a large regional property can make the map reference confusing during a physical inspection.
Choose the satellite your receiver or service actually uses. Satellite names can be similar, and a dish may be aimed at a nearby orbital position while receiving a different service or beam. SatPointer’s available satellite list is useful for checking the satellite entry, coverage information and estimated dish-size requirements before comparing angles.
The application can provide the calculated azimuth and elevation from your selected location. Azimuth describes the horizontal direction, usually measured clockwise from north, while elevation describes how high above the horizon the dish should point. Depending on the service and equipment, you may also need to consider polarisation or LNB skew. Treat these figures as an alignment reference rather than a reason to loosen hardware immediately.
Compare the calculated direction with the dish
SatPointer’s map view helps you understand where the dish should face from the property. Use a reliable compass or a phone compass as a rough field check, remembering that nearby metalwork, vehicles, fences and the dish itself can affect the reading. Australian properties often have large steel sheds, water tanks or solar equipment nearby, so take the compass reading a short distance away from those objects.
The face of an offset dish can be misleading. The reflector may appear to point much higher or lower than the actual incoming signal angle because the feed geometry redirects the beam. Do not use the visible face of the reflector as a simple protractor. Instead, compare the calculated direction with the mast, bracket adjustment and the dish’s previous position.
For a more detailed explanation of the process, the Intelsat pointing guide shows how satellite position, azimuth and elevation work together. This is particularly helpful when a storm has caused a subtle shift rather than an obvious change in the dish’s appearance.
Make small adjustments and watch signal quality
If the mounting hardware is safe to access and the dish has clearly moved, loosen the adjustment bolts only enough to allow controlled movement. Mark the original position with a pencil or weather-resistant marker. Then make very small horizontal changes, followed by small vertical changes, while checking the receiver’s signal quality screen.
Signal quality is generally more useful than signal strength. A receiver may display strength even when the dish is aimed at the wrong satellite, while quality responds more directly to a usable locked signal. Wait several seconds after each adjustment because the receiver may need time to reacquire the transponder. Avoid swinging the dish back and forth quickly, which makes it difficult to identify the best position.
Once quality improves, fine-tune in tiny increments around that point. If the service uses a particular LNB skew, rotate the LNB carefully according to the calculated polarisation setting. Do not force a seized connector or twist the coaxial cable. A damaged cable can create a fault that looks exactly like poor dish alignment.
Confirm the result across weather and services
After restoring reception, check several channels or transponders rather than relying on one picture. A dish that is only slightly off target may show acceptable performance on a strong service but fail on a weaker transponder or during rain. This matters for households in remote Western Australia, South Australia and the outback, where replacement equipment and technician visits can take longer.
Record the final azimuth, elevation, LNB position and any receiver readings. Take a photo of the bracket and cable routing from the ground if possible. Keeping these details can make the next inspection faster after a summer storm, especially when the dish is mounted above a two-storey home or on a rural mast.
If alignment appears correct but reception remains unreliable, investigate the rest of the system. Check for a cracked LNB cover, a bent arm, waterlogged cable, corrosion, tree growth into the line of sight or a failing power supply. Trees near coastal New South Wales and fast-growing vegetation around Brisbane can gradually obstruct a signal even when the dish itself has not moved. When professional help is needed, the SatPointer network can help locate relevant satellite-alignment resources and services.
Use SatPointer to calculate the expected direction from your Australian property, compare it with the dish’s physical position and make only safe, measured adjustments. After confirming signal quality on several services, secure the hardware, weatherproof any exposed connections and keep a record of the final settings for the next storm check.
