摘要： A highly compact and lightweight 82 channel all banded VHF-UHF television antenna having three antenna elements wherein each element is the identical physical length and each element includes two half sections. Each antenna element is separated a predetermined distance from each other element wherein the predetermined distance is substantially less than one-tenth of the shortest wave length in the VHF band. A first set of coils are utilized to electrically lengthen the halves of the two elements for reception in the VHF band and a second set of coils are utilized to provide proper delays between the signals received by each antenna element so that when the signals are combined the signals are substantially additive and in phase. The antenna system includes a weatherproof housing containing a rotor, a preamplifier, and electronic circuitry. A deloading mechanism is arranged around the housing to engage the circumference of each antenna element to provide stability under the driving forces that may occur in the atmosphere.

摘要： An antenna 10 comprises at least a first pair 12 of elongate radiating elements and a second pair 14 of elongate radiating elements. Each pair comprises a first element 12.1 and a second element 12.2. Each element has a feed end 12.11 and a distal end 12.12. The first and second elements of each of the at least first pair and second pair have their respective feed ends 12.1 1, 12.21 in juxtaposition relative to one another and extend in diverging relationship relative to one another in a direction from their feed ends towards their distal ends. The at least first and second pairs are electrically connected in parallel. In some embodiments the elements may diverge exponentially. The invention also relates to antennas which may be packaged in at least partially knock-down form to be assembled or deployed conveniently at a user site.

摘要： An apparatus that achieves high isolation between dipoles and feed systems is provided. The apparatus includes a plurality of transmission lines, a first dipole electrically connected to a first set of the plurality of transmission lines, and second dipole electrically connected to a second set of the plurality of transmission lines. The electric field of the first dipole is parallel to an electric field of the first set of the plurality of transmission lines, and an electric field of the second dipole is parallel to an electric field of the second set of the plurality of transmission lines.

摘要： A substantially hollow block--formed of initially separate halves secured together as a rigid unit--engaged on the upper end of a tubular mast, with bolts in the block projecting from opposite sides thereof, and the bolts mounting the opposed arms of an antenna on the block; the antenna lead extending into the block from within the mast, and the lead wires being attached in the block to said bolts. Improved instrumentalities are associated with the block and separately function to prevent rotation of the block relative to the mast whereby directional orientation of the antenna is maintained; to preclude twisting, as well as longitudinal movement, of the antenna lead in the block so that the antenna wires cannot be accidentally detached from the bolts; and to prevent rotation of the bolts in the block and hence avoid otherwise resultant breaking-off of said attached antenna wires.
