The world of satellite television can be confusing, especially for those navigating the intricacies of Bell ExpressVu's satellite network. Many users encounter questions regarding the differences between satellites 82 and 91, particularly concerning channel availability and signal reception. This article aims to clarify the situation surrounding ExpressVu channels, specifically focusing on the relationship between satellites 82 (Nimiq 4) and 91 (Nimiq 6), and addressing common issues faced by users.
Difference Between 82 & 91:
The primary difference between Bell ExpressVu satellites 82 (Nimiq 4) and 91 (Nimiq 6) lies in their age and the type of channels they carry. Nimiq 4 (82) is an older satellite, primarily carrying standard-definition (SD) channels and some older high-definition (HD) channels. Nimiq 6 (91), being newer, is predominantly used for HD channels and offers newer technology, resulting in potentially better signal quality and more robust transmission. While satellite 91 (Nimiq 6) is the newer and currently preferred satellite for HD programming, satellite 82 (Nimiq 4) remains operational, primarily carrying SD channels and supporting some older HD channels. The statement that 91 will remain in use because it's newer is entirely accurate. The significant investment in Nimiq 6 makes its decommissioning unlikely in the foreseeable future.
The crucial point to understand is that Bell ExpressVu doesn't simply switch channels from one satellite to another. Instead, they strategically distribute channels across both satellites to optimize bandwidth and maintain service. This means some channels might be found on 82, some on 91, and some potentially on both (though redundancy is less common). This distribution is not always transparent to the end-user, leading to confusion and troubleshooting challenges. The channel numbers themselves (like the example of Channel 600) don't directly indicate the satellite origin. The actual satellite used for a specific channel is determined by Bell's internal network routing.
Can't Get My Dish to Pick Up Both 82 & 91 at the Same Time:
This is a common problem, and the solution hinges on the size and type of your satellite dish, its alignment, and the location of your home. Older, smaller dishes might struggle to receive signals from both satellites simultaneously due to their differing orbital positions and the resulting wider angle required for reception. The satellites are not directly adjacent in the sky; they are separated by a significant angular distance. A single dish can receive signals from both, but it requires precise alignment and often a larger dish (generally 18 inches or larger) with a dual-satellite LNB (Low-Noise Block downconverter). An 18'' Bell ExpressVu and Dish Satellite Antenna is often sufficient for high-definition viewing from both satellites, but even with an appropriately sized dish, professional installation is frequently recommended to ensure optimal alignment and signal strength.
Incorrect dish alignment is the most frequent cause of this issue. Even a small misalignment can significantly impact signal reception, particularly for weaker signals from one of the satellites. Many factors influence the optimal alignment, including obstructions (trees, buildings), atmospheric conditions, and even the elevation of your location.
