DIRECTV has suffered outages during rainstorms since it first launched nearly 30 years ago. You will be watching your favorite show when suddenly the signal disappears. Sometimes, it doesn’t even have to rain particularly hard to lose the picture.
The satcaster last year introduced a new feature, called SignalSaver, which enables you to switch to its streaming service when the satellite picture goes out. If your receiver is connected to the Internet, a Keep Watching prompt will appear on the screen when the outage occurs. You click on that and then a ‘Loading Streaming Content’ will display. The missing channel will begin streaming within seconds. Your receiver will then attempt to load the program using the satellite signal. But if the signal is not available, the ‘Keep Watching With Broadband’ option will display until the satellite signal returns.
Although DIRECTV’s streaming version does not have every channel that’s on satellite, it does have the most popular networks. You can see a list here.
This is not a perfect solution, particularly since some channels are missing, but it’s a life saver as well as a signal saver if the outage is a long one.

We thought it would be interesting to explain why the satellite rain outages occur. (Dish has them, too.)
As a subscriber of DIRECTV, you may have experienced frustrating signal outages during rainy weather. These interruptions can disrupt your favorite shows, sports events, or movie marathons. While it may seem puzzling at first, the phenomenon behind DIRECTV signal outages during rain has a scientific explanation. In this article, we delve into the factors contributing to this issue, shedding light on the technical aspects involved.
1. Satellite Communication
DIRECTV operates through satellite communication, relying on signals transmitted between satellites in space and receivers installed on your premises. This setup offers a wide range of channels and access to programming across large geographical areas. However, it is susceptible to certain environmental factors, including rain.
2. The Role of Rain Attenuation
Rain attenuation refers to the absorption and scattering of electromagnetic signals by raindrops. When it rains, the precipitation acts as an obstruction for the radio frequency signals sent from the satellites to your receiver. Raindrops cause signal attenuation by absorbing and deflecting a portion of the signal’s energy. The more intense the rainfall, the greater the likelihood of signal loss.
3. Frequency Dependency
Different frequencies are used for various types of communication, including satellite television. In the case of DIRECTV, the signals are transmitted using Ku-band and Ka-band frequencies. These frequencies are higher than those used by traditional cable or over-the-air television, enabling more data to be transmitted and received. However, they are also more susceptible to rain attenuation.

Ku-band frequencies, utilized by most DIRECTV satellites, fall within the range of 12-18 GHz. While they offer higher bandwidth for delivering High-Definition programming, they are more susceptible to rain attenuation than lower frequencies. Ka-band frequencies, employed by some newer DIRECTV satellites, operate in the range of 26-40 GHz, which further exacerbates the potential for signal degradation during rainfall.
4. Signal Loss and Signal-to-Noise Ratio
The intensity of the rain and the distance the signal must travel through it play a significant role in signal loss. As rain attenuates the signal, it weakens the overall strength received by your DIRECTV dish. If the signal becomes too weak, your receiver struggles to decipher the data, leading to a complete or partial signal loss.

Moreover, the signal-to-noise ratio (SNR) also affects the quality of your DIRECTV signal. SNR refers to the ratio of the desired signal strength to the background noise. Rain attenuation increases the noise level, making it harder for the receiver to distinguish the signal from the noise. Consequently, the lower SNR can cause pixelation, freezing, or complete signal loss.
5. Mitigating Solutions
To counteract signal outages during rain, DIRECTV employs several techniques:
a. Larger Dish Size: A larger satellite dish can capture more signal, compensating for the losses caused by rain attenuation. DIRECTV installers often recommend larger dish sizes in areas prone to heavy rainfall.
b. Signal Strength Adjustment: DIRECTV receivers are designed to automatically adjust the signal strength. In light rain, the signal may not be affected significantly, but during heavy rainfall, the receiver will attempt to compensate for the attenuation by boosting the signal power.
c. Redundancy: DIRECTV uses multiple satellites to provide coverage, which increases the chances of uninterrupted service. If one satellite experiences signal degradation due to rain, the receiver can switch to a different satellite with a stronger signal.

Conclusion
While DIRECTV offers a wide range of programming and access to entertainment, its reliance on satellite communication makes it susceptible to rain attenuation. Raindrops obstruct and weaken the signal, resulting in outages and diminished signal quality during rainy weather. By understanding the technical aspects behind this phenomenon, subscribers can appreciate the challenges and potential solutions offered by DIRECTV, such as larger dish sizes, signal adjustments, and redundant satellite coverage.

SO ChatGPT who wrote this didnt talk about the signal saver part at all.
Because it was covered in the beginning.
