ABSTRACT:
A digital indoor antenna device having a casing, a pivotal seat, a circular antenna having two ends and a PCB in the casing. The pivotal seat attached to the casing has two mounting holes respectively in which the two ends of circular antenna are mounted. The circular antenna rotates on the casing to adjust the horizontal receiving angle. Therefore, the circular antenna device can receive larger intensity of horizontal polarized signals. In addition, the pivotal seat can be pivotally connected to the casing, so the circular antenna can rotate horizontally on the casing to search for different channel signals.
