1. A rotational antenna, comprising:
- a stationary feed which is disposed in a substantially vertical orientation; and
a parabolic dish rotationally mounted about the stationary feed in a state of being tipped with respect to the stationary, substantially vertically oriented feed such that the parabolic dish points upward rather than horizontal, the stationary feed extending through an opening in the parabolic dish,wherein the stationary feed remains fixed at all times during operation of the antenna, andwherein the stationary feed comprises a stationary feed column, a radio frequency (RF) feed, and a separate acoustic feed which includes at least one pipe for carrying sound, with the at least one pipe extending up through the stationary feed column.

Abstract
A rotational antenna includes a stationary feed which is disposed in a substantially vertical orientation. A parabolic dish is rotationally mounted about the stationary feed in a state of being tipped with respect to the stationary, substantially vertically oriented feed. The rotational parabolic antenna may alternatively be provided with a rotating radio frequency (RF) and acoustic feed. Other embodiments are disclosed.
