ABSTRACT:
There is disclosed herein a four-way antenna system having a hollow antenna body to which four antennae are attached and which can be mounted on the outside of a land, sea or air transport vehicle. The first antenna, mounted on the top of the antenna body, receives radio signals. The second antenna, also mounted on the top of the antenna body, receives VHF signals. The third antenna, mounted on the side of the antenna body, receives and transmits telephone signals. The fourth antenna, also mounted on the side of the antenna body, receives and transmits CB signals. An aluminum reflector is attached to the antenna body to reduce no interference between CB amd VHF signals. The four antennae are attached to the antenna body in such a manner that interference between all the incoming and outgoing signals are minimized. In addition, the entire system is small and compact, and can be easily mounted on the outside of any land, sea, or air transport vehicle.
