What type (make/model) antenna are you using? Does the antenna require a power adapter and is it receiving power?
Have you tried a channel scan (via the TV's setup menu) with the antenna attached?
Connected and channel scan performed but no channels foundPlease post a link to the actual product.
When it is connected to your TV and powered on, did you run a channel scan on the TV?
