Abstract
Abstract A combination Hertz and loop-type antenna which effectively receives both electromagnetic and waves of radio and TV broadcasts by virtue of oppositely extending elongated outer tubular conductors that concentrically surround an inner conductor and are held in annularly spaced relationship by conductive elements located near the ends of the conductors and insulating spacers medially thereof. The inner conductor is used to clamp onto a vertical mast by means of a clamp to thereby fix the antenna in a substantially horizontal position, and terminals are provided for connecting insulated output leads to the outer conductors adjacent their inner ends.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
146 words
A hybrid antenna comprising in combination: a cylindrical inner conductor, two tubular cylindrical outer conductors arranged in axial alignment with their respective inner ends spaced from each other, and concentrically spaced around said inner conductor, each of the respective outer ends of said outer conductors being substantially in alignment with one of the outer ends of said inner conductor, insulating spacer means located between said inner conductor and each of the inner ends of said outer conductor to maintain concentricity between said conductors, electrically conductive members located near the outer ends of said inner and outer conductors for completing an electric circuit thereinbetween and for securing said conductors in spaced relationship with each other, a plurality of capacitor disks located on each of said outer conductors adjacent the remote ends thereof, and means for connecting insulated output leads to the inner ends of said outer conductors.
Claim 2
Dependent Claim

A hybrid antenna comprising in combination: a cylindrical inner conductor, two tubular cylindrical outer conductors arranged in axial alignment with their respective inner ends spaced from each other, and concentrically spaced around said inner conductor, each of the respective outer ends of said outer conductors being substantially in alignment with one of the outer ends of said inner conductor, insulating spacer means located between said inner conductor and each of the inner ends of said outer conductor to maintain concentricity between said conductors, electrically conductive members located near the outer ends of said inner and outer conductors for completing an electric circuit thereinbetween and for securing said conductors in spaced relationship with each other, a plurality of capacitor disks located on each of said outer conductors adjacent the remote ends thereof, and means for connecting insulated output leads to the inner ends of said outer conductors.
Claim 3
Dependent Claim
45 words
The invention as defined in claim 1 further comprising clamping means connected to said inner conductor, and a vertical mast attached to said clamp whereby said antenna will be clamped to said mast with said conductors thereof extending substantially at right angles to said mast.
