TILT ADAPTER FOR DIPLEXED ANTENNA WITH SEMI-INDEPENDENT TILT

摘要

A tilt adapter configured to facilitate a desired tilt of a first radio frequency (RF) band and a second RF band of an antenna is disclosed. The antenna supports two or more frequency bands, in which the vertical tilt of each of the supported frequency bands is separately controlled by a coarse level of phase shifting, but commonly controlled by a fine level of phase shifting.

主权项

1. A tilt adapter configured to facilitate a desired tilt of a first radio frequency (RF) band and a second RF band of an antenna, the tilt adapter comprising:
a first rod coupled to at least one first coarse phase shifter; a second rod coupled to at least one second coarse phase shifter; a cross linkage member operatively engaged to both the first and second rods; a first rack coupled to the cross linkage member; a second rack coupled to the first rack, at least one first fine phase shifter, and at least one second fine phase shifter, wherein lateral movement of the first rod or the second rod causes lateral movement of the second rack.
