First Claim
Patent Images
1. A rotational antenna, comprising:
- a rotational parabolic dish; and
a rotational feed which is disposed on the rotational parabolic dish for rotation therewith, the rotational feed comprising at least one rotating radio frequency (RF) feed and at least one separate rotating acoustic feed which is provided on the at least one rotating RF feed,wherein the at least one rotating RF feed includes a coaxial input which extends from the center of the rotational parabolic dish,wherein the at least one separate rotating acoustic feed comprises at least one pipe with a horn for broadcasting acoustic energy onto the parabolic dish, andwherein an end of the at least one pipe having the horn is mounted to the at least one rotating RF feed and the at least one pipe extends radially outwardly from the at least one rotating RF feed such that an opposite end of the at least one pipe is connected with an electrical device.

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.
