Appeal No. 96-1637
Application 08/130,940
Figure 4 illustrates an antenna formed by a single
ungrounded wire 40. The wire is attached at one end to tuner 18
which is grounded to seawater by a wire 44 passing through a hole
42 in the sea ice. The second end of the wire 40 is connected to
a reel 45 for winding and unwinding the antenna wire.
Figure 5 illustrates yet another embodiment wherein a
series inductor 46 is used to reduce the physical length of wire
40 needed to have an effective antenna. The inductor 46 is
connected between the tuner 18 and an end of the wire 40.
The Prior Art
Hine discloses an antenna of metal elements buried in
the earth or located in the sea. The natural conductivity of the
wet earth and sea is used to carry low and extra low frequency
signals to and from the antenna.
Rogers discloses an antenna comprising wires laid
directly on, or buried in, the earth and parallel to the surface
thereof. In Figure 8, Rogers illustrates the antenna supported on
the surface of water. The reference indicates that signals can be
sent and received by the antenna with great facility.
