Ghosting is a visual artifact where a secondary, fainter image appears slightly offset from the primary image on a screen. In analog broadcast television, it happens when the radio frequency signal bounces off buildings or terrain, arriving at the antenna slightly later than the direct signal. In digital displays, it refers to the visible trail left behind moving objects due to slow pixel response times.

Adjust the Yagi antenna slightly to the left, we're still getting some ghosting on the VHF channels.
