Signal strength is only captured once, during the initial scan. It is not live (real-time), making it difficult to use when aiming your antenna.
To be honest, we were at first taken slightly aback by the concept. Where are my channels? What’s on at 7PM? In playing with the unit over several weeks we realized that Tablo is right on track with the way people and cord-nevers (the younger generation that will watch AppleTV instead of cable) are currenty using the ol’tube.
Although Tablo commands, menus and the overall UI is only available in English, programming synopsis and descriptions will display in their native language, like French (above).
Tablo's tuner is very good, but will not magically solve issues related to antenna performance such as multipath or co-channel interference. As with any sensitive ATSC OTA tuner, use a good quality antenna, aim it properly and ensure distribution of your TV signal is as noise-free as possible.
