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.
Claims5
A digital indoor antenna device, comprising:
- a casing having a top and a bottom;
- a pivotal seat attached to the top of the casing and having:
- a closed top;
- an open bottom;
- a vertical sidewall;
- two mounting holes formed through the sidewall diametrically opposite to each other;
- and
- two antenna rails formed on and extending down from the top inside the pivotal seat and corresponding respectively to the mounting holes;
- a circular antenna pivotally mounted in the pivotal seat and having two ends, each end having a spindle connected to a corresponding antenna rail of the pivotal seat through a corresponding mounting hole in the pivotal seat and having
- a neck rotatably mounted in the corresponding mounting hole;
- and
- at least one wheel rotatably mounted in the corresponding antenna rail;
- and
- a PCB with a signal processing function mounted in the casing, electronically connected to the circular antenna and having
