Abstract

Abstract A portable transceiver antenna is provided with a base suitable for retention by a fishing rodholder or for hand held use and is pretuned to facilitate its use without a ground plane. The antenna includes an electrically conductive rod which may be covered by a dielectric and segmented, and would then include couplings fabricated from ferrules closely fitted over nipples to produce reliable electrical contact through the coupling. The antenna may be used with citizens band, very high frequency - frequency modulated, and similar applications.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 153 words
A portable transceiver antenna comprising: a conductor embedded in a resilient dielectric covering thereby defining a rod which is divided into a plurality of completely separable segments having at least one coupling for electrical connection therebetween, said coupling including a male ferrule and female ferrule with each ferrule having a base passing over the dielectric covering and with each ferrule closely fitted over nipples in contact with the conductor thereby establishing reliable electrical contact through the coupling, holding the ferrules in place, and for ease and efficiency of manufacturing assembly; a nonconductive base supporting the rod having a larger diameter than the rod and a friction inducing butt cap at its lowest extremity rendering the base suitable for retention by a conventional fishing rodholder, for hand held use and manual orientation; a wire of coaxially shielded cable for removably attaching the rod to a transceiver; and a tuning stub connected to the wire.
Claim 2
Dependent Claim 153 words
A portable transceiver antenna comprising: a conductor embedded in a resilient dielectric covering thereby defining a rod which is divided into a plurality of completely separable segments having at least one coupling for electrical connection therebetween, said coupling including a male ferrule and female ferrule with each ferrule having a base passing over the dielectric covering and with each ferrule closely fitted over nipples in contact with the conductor thereby establishing reliable electrical contact through the coupling, holding the ferrules in place, and for ease and efficiency of manufacturing assembly; a nonconductive base supporting the rod having a larger diameter than the rod and a friction inducing butt cap at its lowest extremity rendering the base suitable for retention by a conventional fishing rodholder, for hand held use and manual orientation; a wire of coaxially shielded cable for removably attaching the rod to a transceiver; and a tuning stub connected to the wire.
Claim 3
Dependent Claim 202 words
A portable transceiver antenna comprising: a conductor embedded in a resilient dielectric covering thereby defining a rod which is divided into a plurality of completely separable segments having at least one coupling for electrical connection therebetween, said coupling including a male ferrule and a female ferrule with each ferrule having a base passing over the dielectric covering and with each ferrule closely fitted over and in reliable electrical contact with nipples in electrical contact with the conductor, thereby establishing reliable electrical contact through the coupling, holding the ferrules in place, and for ease and efficiency of manufacturing assembly; a nonconductive hollow base supporting the rod, having a larger diameter than the rod and a friction inducing butt cap at its lowest extremity rendering the base suitable for retention by a conventional fishing rodholder, for hand held use and manual orientation, said base further containing a resonating capacitor connected in series between the conductor and a wire, and sealant protectively immersing the contents of the base, said sealant limited by a stopper and a collar; a wire of coaxially shielded cable for removably attaching the rod to a transceiver, said wire connected to the capacitor; and a tuning stub connected to the wire.
Claim 4
Dependent Claim 202 words
A portable transceiver antenna comprising: a conductor embedded in a resilient dielectric covering thereby defining a rod which is divided into a plurality of completely separable segments having at least one coupling for electrical connection therebetween, said coupling including a male ferrule and a female ferrule with each ferrule having a base passing over the dielectric covering and with each ferrule closely fitted over and in reliable electrical contact with nipples in electrical contact with the conductor, thereby establishing reliable electrical contact through the coupling, holding the ferrules in place, and for ease and efficiency of manufacturing assembly; a nonconductive hollow base supporting the rod, having a larger diameter than the rod and a friction inducing butt cap at its lowest extremity rendering the base suitable for retention by a conventional fishing rodholder, for hand held use and manual orientation, said base further containing a resonating capacitor connected in series between the conductor and a wire, and sealant protectively immersing the contents of the base, said sealant limited by a stopper and a collar; a wire of coaxially shielded cable for removably attaching the rod to a transceiver, said wire connected to the capacitor; and a tuning stub connected to the wire.
Claim 5
Dependent Claim 118 words
A portable transceiver antenna comprising: a conductor embedded in a resilient dielectric covering thereby defining a rod which is divided into a plurality of completely separable segments having at least one coupling for electrical connection therebetween, said coupling including a male ferrule and female ferrule with each ferrule having a base passing over the dielectric covering and with each ferrule closely fitted over and in reliable electrical contact with nipples in electrical contact with the conductor; a nonconductive base supporting the rod and suitable for hand held use, manual orientation and retention by a conventional fishing rodholder; a wire of coaxially shielded cable for removably attaching the rod to a transceiver; and tuning means connected to the wire.
Claim 6
Dependent Claim 118 words
A portable transceiver antenna comprising: a conductor embedded in a resilient dielectric covering thereby defining a rod which is divided into a plurality of completely separable segments having at least one coupling for electrical connection therebetween, said coupling including a male ferrule and female ferrule with each ferrule having a base passing over the dielectric covering and with each ferrule closely fitted over and in reliable electrical contact with nipples in electrical contact with the conductor; a nonconductive base supporting the rod and suitable for hand held use, manual orientation and retention by a conventional fishing rodholder; a wire of coaxially shielded cable for removably attaching the rod to a transceiver; and tuning means connected to the wire.
Claim 7
Dependent Claim 16 words
The portable transceiver antenna of claim 3 wherein the resilient dielectric covering is comprised of fiberglass.
Claim 8
Dependent Claim 64 words
The portable transceiver antenna of claim 3 wherein the tuning means is comprised of another coaxially shielded cable having a first end of its coaxial shielding connected to the coaxial shielding of the wire, having a first end of its cable connected to the cable of the wire, and having a second end of its cable connected to a second end of its shielding.
Claim 9
Dependent Claim 56 words
The portable transceiver antenna of claim 3, wherein the tuning means comprises a hollow cylindrically wound coil having internal threads and two terminals, the first of which is connected to the conductor and the second of which is connected to the cable of the wire; and an externally threaded metallic slug having a screwdriver slot therein.
Claim 10
Dependent Claim 32 words
The portable transceiver antenna of claim 3 wherein the base comprises a member of greater diameter than the electrically conductive rod and includes at its lowest extremity a friction inducing butt cap.
