Claim:
A communication carrying apparatus comprising: a bearing structure having four tubes extending upwardly from a bottom to a top, each of said four tubes having a slightly truncated conical shape, two of said four tubes extending in a first plane and another two of said four tubes extending in a second plane intersecting said first plane, said bottom having a cross-sectional area greater than a cross-sectional area at said top, the top of said four tubes being joined together at a top of said bearing structure and radiating outwardly therefrom, each of four tubes being inflated at a relative pressure of between 0.15 and 0.8 bars, each of said four tubes having an internal elastic impermeable envelope and an external envelope formed of an inelastic tear-resistant materials; a base affixed to said bottom of each of said four tubes, said base suitable for resting on an underlying surface, the base of said four tubes being spaced from and connected with each other; a first transversal tube affixed to and extending between a first pair of said four tubes in spaced relation to said top of said bearing structure and in spaced relation to said base; a second transversal tube affixed to and extending between a second pair of said four tubes in spaced relation to said top of said bearing structure and in spaced relation to said base; a first flexible panel affixed so as to be bounded only between said first pair of said four tubes and said first transversal tube, said first flexible panel having visible information thereon; and a second flexible panel affixed so as to be bounded only between said second pair of said four tubes and said second transversal tube, said second flexible panel having visible information thereon.
