Hybrid cable antenna for high frequency band

1. A cable antenna for operation in the high frequency band, comprising:

a first cable antenna that is buoyant and unloaded for operation in a lower portion of the high frequency band;

at least one second cable antenna serially and electrically coupled to said first cable antenna, each said second cable antenna being buoyant and loaded for operation in a portion of the high frequency band that is above said lower portion;

wherein each said second cable antenna comprises a serial arrangement of electrically-connected capacitors, said capacitors being evenly spaced in said serial arrangement, each of said capacitors having the same capacitance; and

a buoyant and electrically-insulating jacket enclosing said serial arrangement.

2. A cable antenna as in claim 1 , wherein said first cable antenna comprises:

a single conducting wire; and

a buoyant and electrically-insulating jacket encasing said wire.

3. A cable antenna as in claim 1 , wherein each said second cable antenna is capacitively loaded.

4. A cable antenna as in claim 1 , further comprising a bandpass filter electrically coupled between said first cable antenna and said at least one second cable antenna.

5. A cable antenna as in claim 1 , wherein said at least one second cable antenna comprises a plurality of second cable antennas, wherein said portion of the high frequency band associated with each of said second cable antennas is unique.

6. A cable antenna as in claim 1 , wherein said at least one second cable antenna comprises a serial plurality of second cable antennas, wherein said portion of the high frequency band associated with each of said second cable antennas is a unique non-overlapping band of the high frequency band, and wherein said unique non-overlapping band associated with each said portion increases in frequency with distance from said first cable antenna.

7. A cable antenna as in claim 6 , further comprising a bandpass filter electrically coupled to and between adjacent ones of said second cable antennas.

8. A cable antenna as in claim 1 , wherein said first cable antenna and said at least one second cable antenna are flexible.

9. A cable antenna for operation in the high frequency band, comprising:

a first cable antenna that is buoyant and unloaded for operation in a lower portion of the high frequency band, said first cable antenna defined by a single conducting wire encased in a buoyant and electrically-insulating jacket; and

at least one second cable antenna serially and electrically coupled to said first cable antenna, each said second cable antenna being buoyant and loaded for operation in a portion of the high frequency band that is above said lower portion, each said second cable antenna defined by (i) a serial arrangement of electrically-connected and evenly-spaced capacitors, each of said capacitors having the same capacitance, and (ii) a buoyant and electrically-insulating jacket enclosing said serial arrangement.

10. A cable antenna as in claim 9 , further comprising a bandpass filter electrically coupled between said first cable antenna and said at least one second cable antenna.

11. A cable antenna as in claim 9 , wherein said at least one second cable antenna comprises a plurality of second cable antennas, wherein said portion of the high frequency band associated with each of said second cable antennas is unique.

12. A cable antenna as in claim 9 , wherein said at least one cable antenna comprises a serial plurality of second cable antennas, wherein said portion of the high frequency band associated with each of said second cable antennas is a unique non-overlapping band of the high frequency band, and wherein said unique non-overlapping band associated with each said portion increases in frequency with distance from said first cable antenna.

13. A cable antenna as in claim 12 , further comprising a bandpass filter electrically coupled to and between adjacent ones of said second cable antennas.

14. A cable antenna as in claim 9 , wherein said first cable antenna and said at least one second cable antenna are flexible.
