Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
An antenna equipment for a UHF tuner, comprising: a supporting member made from an insulator and adapted to be fixed to a wall of a chassis of the UHF tuner, two antenna pins fastened to said supporting member, each of said two antenna pins having its one end protruded outwardly of said supporting member and its base end part exposed in the chassis side of said UHF tuner; an antenna coil arranged inside said UHF tuner and electrically coupled with the base end parts of said antenna pins through an opening formed in said UHF tuner; a fixed resistor arranged on the outer wall of said chassis of said UHF tuner, one of the two leads of said resistor being electrically connected to either of said two antenna pins and the other of said two leads being electrically connected to said chassis of said UHF tuner; and a cover member made from an insulator and adapted to be fixed to said wall of said chassis of said UHF tuner and to be mechanically coupled with said supporting member, said cover member covering said fixed resistor outside said chassis of said UHF tuner.
Claim 2
Dependent Claim
192 words
An antenna equipment for a UHF tuner, comprising: a supporting member made from an insulator and adapted to be fixed to a wall of a chassis of the UHF tuner, two antenna pins fastened to said supporting member, each of said two antenna pins having its one end protruded outwardly of said supporting member and its base end part exposed in the chassis side of said UHF tuner; an antenna coil arranged inside said UHF tuner and electrically coupled with the base end parts of said antenna pins through an opening formed in said UHF tuner; a fixed resistor arranged on the outer wall of said chassis of said UHF tuner, one of the two leads of said resistor being electrically connected to either of said two antenna pins and the other of said two leads being electrically connected to said chassis of said UHF tuner; and a cover member made from an insulator and adapted to be fixed to said wall of said chassis of said UHF tuner and to be mechanically coupled with said supporting member, said cover member covering said fixed resistor outside said chassis of said UHF tuner.
Claim 3
Dependent Claim
29 words
An antenna equipment according to claim 1, wherein said supporting member is provided with an engaging portion for engaging a groove formed in said outer wall of said chassis.
Claim 4
Dependent Claim
33 words
An antenna equipment according to claim 2, wherein said supporting member is unitarily formed with a holder portion for holding said fixed resistor, and said cover member is coupled with said holder portion.
Claim 5
Dependent Claim
28 words
