Abstract

A range accentuating device for remote control transmitters, used in connection with automobile and other types of accessories and options, is provided. The invention is comprised of an antenna, and a receptacle to couple the remote control transmitter, via mutual coupling, to the antenna. When the remote control transmitter is coupled to the antenna and the remote control transmitter is activated, the signal from the remote control transmitter is accentuated.

Claims

1. A range accentuator for use with hand-held remote control transmitters comprising:

a base;

said base having means for receiving a remote control transmitter via mutual coupling;

a first antenna extending from said base;

a second antenna extending from said base, one-half of a pre-defined wave length longer than said first antenna; and

an electrically conductive rod, carried by said base, having one end attached to said first antenna and a second end attached to said second antenna, such that when said remote control transmitter is received by said base and activated said rod receives a signal and accentuates said signal via said antennas.

2. The range accentuating device of claim 1, wherein a cavity is defined within said base and a plate is placed within said cavity to provide stability and prevent de-tuning of said antennas by exterior metal surfaces.

3. The range accentuating device of claim 1, wherein a notch is defined on said base enabling the placement of said remote control transmitter on said base.

4. The range accentuating device of claim 1, wherein said antennas are parallel to each other.

5. The range accentuating device of claim 1, wherein the legs of said rod are parallel to each other.

6. The range accentuating device of claim 1 wherein said rod and said antennas are one unit.

7. A range accentuating device for use with a hand-held remote control transmitter comprising:

a sleeve for receiving said remote control transmitter via mutual coupling; and

an electrically conductive bar carried by said sleeve, so that when a remote control transmitter is placed within said sleeve and said remote control transmitter is activated said bar receives a signal and accentuates said signal;

said electrically conductive bar comprising a central bar and two collapsible antenna ends pivotally attached to said sleeve proximal to each end of said bar, such that when said antenna ends are unfolded and extended said antenna ends and said bar combine to form an antenna.

8. A range accentuating device for use with a hand-held remote control transmitter comprising:

a receptacle for holding said hand-held remote control transmitter via mutual coupling;

conducting means, having a first conductor and a second conductor and a first end and a second end, said first end formed as a loop by connecting said conductors to each other at said first end, said loop carried by said receptacle;

an antenna; and

attaching means for connecting said second end of said conducting means to said antenna so that when said remote control transmitter is placed within said receptacle and thereafter activated said antenna receives a transmission and accentuates said transmission.

9. The range accentuating device of claim 8 wherein said conducting means is a coaxial cable.

10. The range accentuating device of claim 8 wherein said conducting means is a twin lead cable.
