What Is Comcast CATV Signal Level?

Cable TV signal strength determines the television picture quality.

Comcast cable signal strength is important to having perfect picture quality. The signal strength can vary at different points in the day, but should always be strong for optimal results on your television.

Decibel Level

The signal level for Comcast is a range between 15 and 40 decibels with possible higher readings under certain network conditions. Perfect picture quality is not always reliant on this and a lower reading can still result in an optimal picture. Picture quality usually suffers when the signal strength dips to 12 decibels.

Network Problems

The signal strength is dependent on the quality of coaxial cable between the node and your house. Most Comcast cable technicians do not have the ability to check anything except the connection between their network (referred to as "the pole") and your house. Problems can also exist in the quality of cable in your house. Everything from the pole to your television can be resolved by a qualified technician as specialized tools are required. These tools are not widely available and are priced for business use.

Comcast's network is built out of several third-party networks, causing several issues with cable quality and cable signal levels that differ from location to location.

Expert Insight and Advice

Comcast cable signal strength is important to cable TV with the advent of On Demand programming. Given the nature of Comcast's network, it is wise to examine signal strength issues. If the signal strength dips low enough where you suffer constant problems, it is recommended you consider another provider.

While the majority of Comcast's network is able to sustain the 15-40 decibel range, a problematic connection indicates serious chronic issues with your local network that require attention at the national level. It is recommended if a technician cannot resolve your issues in two visits that you find another provider.
