What is TV antenna rescanning and why is it necessary?
Rescanning your TV antenna is the process of searching for available broadcast channels. This is essential as local television stations may change their broadcast frequencies or make changes to their signal. These adjustments can occur due to channel reallocations, upgrades, or during the transition to digital broadcasting. Failing to rescan can result in lost channels or decreased reception quality.
Rescanning helps your television or digital tuner detect any new channels that have been added to your area as well as those that may have changed frequencies. Regular rescanning can ensure that you have access to the best possible programming and allow you to enjoy a consistently high-quality viewing experience.
How often should I rescan my antenna?
While there is no set schedule for rescanning your TV antenna, it is advisable to do so anytime you notice a decrease in channel availability or quality. Additionally, you should perform a rescan whenever there are significant changes in your local TV market or if a new broadcasting channel has launched in your area. Staying proactive can help maintain optimal reception.
It can also be beneficial to rescan during major events, such as the FCC’s Channel Repack or after significant weather events, which might affect reception. Keeping a habit of rescanning every few months can also ensure you are up to date with any new programming options and improved signal availability.
