Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
An antenna comprising: an antenna body telescopically extendable from a fully retracted position and having a free end; an electrode member mounted to the free end of said antenna body, said electrode member having a tubular, electrically conductive portion electrically coupled to the antenna body and defining an axial bore; base means for mounting said antenna body to a radio, said base means including a casing member for telescopically mounting said antenna body and a receptacle portion for coaxially receiving said electrode member when the antenna body is in said fully retracted position; said electrode member and said receptacle portion of said base means together forming a coaxial connector receptacle when said antenna body is in said fully retracted position.
Claim 2
Dependent Claim
120 words
An antenna comprising: an antenna body telescopically extendable from a fully retracted position and having a free end; an electrode member mounted to the free end of said antenna body, said electrode member having a tubular, electrically conductive portion electrically coupled to the antenna body and defining an axial bore; base means for mounting said antenna body to a radio, said base means including a casing member for telescopically mounting said antenna body and a receptacle portion for coaxially receiving said electrode member when the antenna body is in said fully retracted position; said electrode member and said receptacle portion of said base means together forming a coaxial connector receptacle when said antenna body is in said fully retracted position.
Claim 3
Dependent Claim
23 words
An antenna according to claim 1 wherein said electrode member further includes a tubular insulator member surroundingly engaging said tubular, electrically conductive portion.
Claim 4
Dependent Claim
37 words
An antenna according to claim 1 and further including means for facilitating the extraction of said electrode member from said axially outer portion of said base means when said antenna body is in said fully retracted position.
Claim 5
Dependent Claim
147 words
An antenna comprising: an antenna body telescopically extendable from a fully retracted position and having a free end; an electrode member mounted to the free end of said antenna body, said electrode member having a tubular, electrically conductive portion electrically coupled to the antenna body and defining an axial bore; base means for mounting said antenna body to a radio, said base means including a casing member for telescopically mounting said antenna body and a receptacle portion for coaxially receiving said electrode member when the antenna body is in said fully retracted position; said electrode member and said receptacle portion of said base means together forming a coaxial connector receptacle when said antenna body is in said fully retracted position; and wherein said receptacle portion of said base means is provided with an external thread surface for receiving a complementary threaded portion of a coaxial connector jack.
Claim 6
Dependent Claim
147 words
An antenna comprising: an antenna body telescopically extendable from a fully retracted position and having a free end; an electrode member mounted to the free end of said antenna body, said electrode member having a tubular, electrically conductive portion electrically coupled to the antenna body and defining an axial bore; base means for mounting said antenna body to a radio, said base means including a casing member for telescopically mounting said antenna body and a receptacle portion for coaxially receiving said electrode member when the antenna body is in said fully retracted position; said electrode member and said receptacle portion of said base means together forming a coaxial connector receptacle when said antenna body is in said fully retracted position; and wherein said receptacle portion of said base means is provided with an external thread surface for receiving a complementary threaded portion of a coaxial connector jack.
Claim 7
Dependent Claim
46 words
An antenna according to claim 4 wherein said base means includes a generally cylindrical mounting member for mounting said casing member and said antenna body to a radio; and wherein said mounting member defines said receptacle portion of said base means including said external thread surface.
Claim 8
Dependent Claim
32 words
An antenna according to claim 5 wherein said mounting member further includes a tubular insulating member coaxially mounted within said external thread surface thereof for coaxially receiving said electrode insulating member therewithin.
Claim 9
Dependent Claim
99 words
An antenna comprising: an antenna body telescopically extendable from a fully retracted position and having a free end; an electrode member mounted to the free end of said antenna body; base means for mounting said antenna body to a radio, said base means including a first portion for telescopically mounting said antenna body and a second portion for receiving said electrode member when the antenna body is in said fully retracted position; said electrode member and said second portion of said base means together forming a coaxial connector receptacle when said antenna body is in said fully retracted position.
Claim 10
Dependent Claim
99 words
An antenna comprising: an antenna body telescopically extendable from a fully retracted position and having a free end; an electrode member mounted to the free end of said antenna body; base means for mounting said antenna body to a radio, said base means including a first portion for telescopically mounting said antenna body and a second portion for receiving said electrode member when the antenna body is in said fully retracted position; said electrode member and said second portion of said base means together forming a coaxial connector receptacle when said antenna body is in said fully retracted position.
Claim 11
Dependent Claim
198 words
An antenna comprising: an antenna body telescopically extendable from a fully retracted position and having a free end; an electrode member mounted to the free end of said antenna body, said electrode member having a tubular, electrically conductive portion electrically coupled to the antenna body and defining an axial bore; base means for mounting said antenna body to a radio, said base means including a casing member for telescopically mounting said antenna body and a receptacle portion for coaxially receiving said electrode member when the antenna body is in said fully retracted position; said electrode member and said receptacle portion of said base means together forming a coaxial connector receptacle when said antenna body is in said fully retracted position; and further including means for facilitating the extraction of said electrode member from said axially outer portion of said base means when said antenna body is in said fully retracted position; said extraction facilitating means comprising an annular groove formed in an outer surface of said electrode member and a cut out portion in said receptacle portion of said base means to permit gripping of said annular groove when said antenna body is in said fully retracted position.
Claim 12
Dependent Claim
198 words
An antenna comprising: an antenna body telescopically extendable from a fully retracted position and having a free end; an electrode member mounted to the free end of said antenna body, said electrode member having a tubular, electrically conductive portion electrically coupled to the antenna body and defining an axial bore; base means for mounting said antenna body to a radio, said base means including a casing member for telescopically mounting said antenna body and a receptacle portion for coaxially receiving said electrode member when the antenna body is in said fully retracted position; said electrode member and said receptacle portion of said base means together forming a coaxial connector receptacle when said antenna body is in said fully retracted position; and further including means for facilitating the extraction of said electrode member from said axially outer portion of said base means when said antenna body is in said fully retracted position; said extraction facilitating means comprising an annular groove formed in an outer surface of said electrode member and a cut out portion in said receptacle portion of said base means to permit gripping of said annular groove when said antenna body is in said fully retracted position.
