Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
213 words
A three-way antenna system comprising: an antenna body having a top and at least one side; a first antenna mounted at the top of said antenna body for receiving VHF signals with an electromagnetic frequency of 30 to 300 MHz; a second antenna and a third antenna selected from the group consisting of: a radio antenna mounted at the top of said antenna body for receiving signals with an electromagnetic frequency of 525 to 1700 kHz and 88 to 108 MHz, a telephone antenna mounted on the side of said antenna body for sending and receiving signals with an electromagnetic frequency of 3 to 5 MHz, and a CB antenna mounted on the side of said antenna body for sending and receiving signals with an electromagnetic frequency of 26 to 28 MHz; means for transmitting said electromagnetic signals received by said first, second and third antennae between said antennae and first, second and third receivers, the first, second and third receivers corresponding to the first, second and third antennae, respectively, wherein said means for transmitting includes a distributor box coupled between said antennae and the receivers; and means for isolating said antennae from each other so that there is no interference between said electromagnetic signals sent and received from each of said antennae.
