Abstract

Abstract 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.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 169 words
An improved block for an antenna unit which includes a tubular mast, a block engaged on the upper end of the mast, the block having a downwardly opening bore in which the upper end of the mast is received, antenna elements, bolts securing the antenna elements to the block, and an antenna lead extending upwardly in the mast and into the block, with the lead wires connected in the block to the bolts; characterized by said improved antenna mounting block comprising, in combination, initially separate but mating halves, said block-halves being rigidly secured together upon inclusion of such block in the antenna unit by engagement on the mast, means between the block and the antenna lead preventing relative motion therebetween, and means between the block and the bolts preventing rotation of the latter; said motion-preventing means between the block and lead comprising a tongue formed with the block and projecting inwardly in intersecting relation to the lead, and the latter having a slot therein through which the tongue projects.
Claim 2
Dependent Claim 169 words
An improved block for an antenna unit which includes a tubular mast, a block engaged on the upper end of the mast, the block having a downwardly opening bore in which the upper end of the mast is received, antenna elements, bolts securing the antenna elements to the block, and an antenna lead extending upwardly in the mast and into the block, with the lead wires connected in the block to the bolts; characterized by said improved antenna mounting block comprising, in combination, initially separate but mating halves, said block-halves being rigidly secured together upon inclusion of such block in the antenna unit by engagement on the mast, means between the block and the antenna lead preventing relative motion therebetween, and means between the block and the bolts preventing rotation of the latter; said motion-preventing means between the block and lead comprising a tongue formed with the block and projecting inwardly in intersecting relation to the lead, and the latter having a slot therein through which the tongue projects.
Claim 3
Dependent Claim 49 words
An antenna mounting block, as in claim 1, in which the initially separate halves of the block have members therein which substantially mate, with the lead engaged therebetween, when said block-halves are rigidly secured together; the point of such engagement with the lead being adjacent but above the tongue.
