Troubleshooting tips for intermittent signal

An intermittent signal is one of the most common issues with Satellite signal interference. If your picture cuts in and out or the red light on your receiver is flickering on and off, there is a good chance you are experiencing Intermittent signal. Follow these steps to troubleshoot intermittent signals with your Satellite dish.

Intermittent signal troubleshooting

Prior to proceeding with the following troubleshooting steps be sure to consider the following:

How is the weather in your area?
If your area is experiencing inclement weather and your signal only became intermittent when the bad weather started, you may just need to wait for their signal to clear up.


Is there something blocking the dish?
If the dish is visible to you, take a look at the sky in the direction it’s facing. Could something such as a tree or snowdrift be blocking the way?


Is the issue happening on only one one receiver?
If you have multiple receivers and the problem is only occurring on one, try swapping it with another receiver in the house to see if the issue persists with the line or only that receiver.

If this your signal issue persists or is affecting all receivers, you can take the following steps to try to rectify it:

  1. Verify connections at the receiver and (if possible) at LNBF or multiswitch.
  2. Trace the coaxial line from dish to receiver and bypass any splitters, joiners, or surge protectors on the line
  3. Inspect the coaxial line for an RG specification written on the side. Shaw direct requires an RG rating of RG6 or higher to work. RG59 cable will tend to work for a short time on some channels before burning out.
  4. Check for possible interference issues in the house and/or close to the dish such as anything that transmits RF frequency (radar stations, CB radio, or smart meters).
  5. If only some channels are intermittent, please take note of which channels those are.
  6. Try unplugging the receiver from the power for one minute and plugging it back in.
