Why Is My DStv Dish Losing Signal?
A faulty DStv dish can lead to frequent signal dropouts, pixelated images, or complete channel loss. Most of the time, it’s not your decoder—it’s the dish setup. Poor alignment, rust, cabling issues, or environmental factors can all affect signal strength. If your viewing is interrupted with error messages like E48-32, it’s a clear sign something needs fixing. You can view a full list of DStv error codes here.
Common Causes of DStv Dish Signal Problems
Signal issues aren’t always as complicated as they seem. Here are the top causes:
- Dish Misalignment: Strong winds or poor installation can shift your dish out of position.
- LNB Failure: The Low Noise Block downconverter may be damaged or corroded.
- Cable Deterioration: Old, exposed coaxial cables can get waterlogged or chewed by rodents.
- Obstructions: Trees, buildings, or new structures can block the signal path.
- Weather Conditions: Heavy rain or dense cloud cover can temporarily affect signal quality.
How to Fix a Misaligned DStv Dish
Your DStv dish must be pointed precisely at the Eutelsat 36B satellite at 36° East. Here’s a simplified DIY method:
- Loosen the bolts on the dish mount.
- Use a satellite finder or your decoder’s signal bar.
- Gently adjust the dish left, right, up, and down.
- Watch for signal strength and quality improvements.
- Once the highest signal is achieved, tighten all bolts.

How to Prevent Rust and Weather Damage
Rust can eat away at your DStv dish and brackets, eventually affecting signal performance. Here’s how to prevent it:
- Use galvanized or powder-coated dishes.
- Apply anti-rust spray annually.
- Check for water ingress in cables and replace damaged sections.
- Install a weatherproof LNB cover.
Many installations fail early due to poor-quality materials. If you’re unsure, consult a Multichoice DStv Accredited Installer to ensure you’re using the best equipment.
What If Your DStv Dish Is Damaged Beyond Repair?
Sometimes, the best fix is a full replacement. If the dish is bent, corroded, or structurally weak, it’s not worth salvaging. In that case:
- Replace the dish with a high-quality 80cm or 90cm model.
- Use a new LNB and ensure all cables are fresh.
- Reinstall with optimal line-of-sight clearance.
A new setup can resolve persistent signal issues for good. If you’re considering an upgrade, check out the DStv Explora XtraView option for multi-room viewing.
Understanding Signal Strength vs. Signal Quality
When diagnosing DStv dish issues, it’s essential to differentiate between signal strength and quality:
| Metric | Meaning | Fix |
| Signal Strength | Raw power of the satellite signal | Check alignment and cables |
| Signal Quality | Accuracy and clarity of the signal received | Remove obstructions and use better LNBs |
Having full signal strength but poor quality often means something is interfering with the signal path.
How to Tell If the LNB Is the Problem
The LNB is the eye of your DStv dish. Signs of failure include:
- No signal or frequent signal drops
- Water damage or visible corrosion
- Cracks in the plastic casing
- Inconsistent channel performance
Replacing the LNB is straightforward and affordable. Just make sure it’s compatible with your decoder and properly aligned.
Cable Management and Replacement Tips
Even a perfectly aligned DStv dish won’t work with faulty cables. Here’s what to look out for:
- Check for frayed or exposed wires.
- Replace any indoor/outdoor cables over 5 years old.
- Use RG6 coaxial cable with compression fittings.
- Seal cable ends with waterproof tape or rubber boots.
For proper routing and concealment, you might also want to bundle cable management with your TV installation or wall mounting service.
When to Call a DStv Dish Installer
If you’ve tried everything and the signal still drops, it’s time to bring in a pro. You should call an installer when:
- Your dish is on a high or dangerous rooftop
- You have persistent error codes after alignment
- You need to connect multiple decoders in one home
- You’re switching to a new satellite or adding OVHD

Can WiFi or Electronics Interfere with Your DStv Dish?
It’s rare, but some household electronics can cause mild interference:
- Cordless phones or baby monitors
- Poorly shielded HDMI or coaxial cables
- Devices operating on similar frequencies
For better indoor connectivity, consider improving your WiFi signal range to isolate network-related viewing issues from satellite dish problems.
