Abstract
A portable and collapsible supporting structure for a multi-element quad antenna comprising a horizontal telescopic boom upon which are mounted several sets of folding spreader arms radiating from the boom, each arm being pivotally connected to it. Each set of spreader arms can be immobilized in a common angular position with the boom, whereby several quadrangular loops may be hung between said spreader arms. The boom is supported by a multi-element mast. The mast itself rests on the hollow cylindrical base which doubles as a sheath for the storage and transporation of the various dismantled elements of the structure.
Claims2
A foldable frame for supporting an electromagnetic radiation antenna which comprises:
- a rigid boom;
- at least one set of foldable arms;
- means for pivotally connecting the first ends of the foldable arms around the boom in a circular pattern;
- means for holding said set of foldable arms in a common angular position with the boom;
- a mast having an extremity orthogonally attachable to the boom;
- and
- base means for supporting said mast in an upright position, said base means comprising:
- a rigid, portable, sealable enclosure which is shaped and dimensioned to form a hand-carrying sheath for housing all of the other components of said foldable frame, and means for mounting the mast above said enclosure, wherein said enclosure comprises:
- a hollow cylinder closed at one end, having an inside length greater than the length of the longest of said components;
- a removable lid having a hold in its center to receive the lower extremity of the mast, and a plurality of projections extending from the lower part of said cylinder.
A foldable frame for supporting an electromagnetic radiation antenna which comprises:
- a rigid boom having at least two sections, one of said sections having one end concentrically engaged into one end of another section;
- at least one set of foldable arms;
- means for pivotally connecting the first ends of the foldable arms around the boom in a circular pattern, said means comprising a flat element concentrically and perpendicularly engaged around the boom, said flat element having a plurality of peripheral indentations, and means for pivotally attaching the end of one of the arms within each indentation;
- means for holding said set of foldable arms in a common angular position with the boom;
- a mast having an extremity orthogonally attachable to the boom;
- and
- base means for supporting said mast in an upright position, said base means comprising a rigid, portable, sealable enclosure which is shaped and dimensioned to form a hand-carryable sheath for housing all other components of said foldable frame, and means for mounting the mast above said enclosure, wherein said enclosure comprises:
- a hollow cylinder closed at one end, having an inside length greater than the length of the longest of said components, a removable lid having a hole in its center to receive the lower extremity of the mast;
- and
- a plurality of projections extending from the lower part of said cylinder.
