An end of the upper mast is inserted within an end of the base and a portion of the base overlaps the upper mast and is fastened thereto, with the cladding surrounding the base. The sealing arrangement comprises a transition ring and a seal assembly. The transition ring surrounds a portion of the base, upper mast and cladding. The transition ring having an internal downwardly facing surface, and the seal assembly is disposed within said transition ring to seal between the external surface of the upper mast and the transition ring. The seal assembly comprising a sealing plate and a seal disposed between the downwardly facing surface and the sealing plate, and the sealing action of the seal assembly is actuated by the sealing plate squeezing said seal. ## Claims ### Claim 1 A pole assembly comprising a base, an upper mast and a cladding, said base comprising a first tubular member of substantially constant cross section, and said upper mast comprising a second tubular member of substantially constant cross section smaller in cross section than said first tubular member, and in use to assemble said pole assembly a free end of said second tubular member is inserted within a free end of said first tubular member so that a portion of said first tubular member overlaps said second tubular member allowing for a plurality of fasteners to removably secure said second tubular member to said first tubular member, and said cladding surrounds said first tubular member and said fasteners, wherein a transition ring is disposed around a portion of said first and second tubular members and said cladding at said free end of said first tubular member, said transition ring having an internal downwardly facing surface, and a seal assembly is disposed within said transition ring to seal between the external surface of said second tubular member and said transition ring, said seal assembly comprising a sealing plate and a seal, said seal being disposed between said downwardly facing surface and said sealing plate, and the sealing action of said seal assembly is actuated by said sealing plate squeezing said seal. ### Claim 2 (depends on 1) A pole assembly as claimed in claim 1, wherein a plurality of screws, each of which pass through said seal into said sealing plate, are used to actuate the sealing plate to squeeze said seal. ### Claim 3 (depends on 1) A pole assembly as claimed in claim 1, wherein said first tubular member comprises a plurality of first longitudinally extending channels that form corresponding longitudinal projections in its interior, and said second tubular member comprises a plurality of second longitudinally extending channels, and wherein said longitudinal projections project into said second longitudinally extending channels, when said second tubular member is inserted into said first tubular member. ### Claim 4 (depends on 3) A pole assembly as claimed in claim 3, wherein said transition ring has a plurality of spaced apart steps, each step projecting into one of said second longitudinally extending channels from the bottom of a recess in said transition ring that open to the top of said transition ring, said downwardly facing surface including the underside of said steps. ### Claim 5 (depends on 4) A pole assembly as claimed in claim 4, wherein each said screw passes through a hole in one of said steps, and said screws are tightened from the outside of said transition ring. ### Claim 6 (depends on 3) A pole assembly as claimed in claim 3, wherein each of said fasteners comprise a bolt that passes through a hole in the bottom of one of said first longitudinally extending channels, and a corresponding hole in the bottom of one of said second longitudinally extending channels, and a nut disposed inside said second tubular member. ### Claim 7 (depends on 6) A pole assembly as claimed in claim 6, wherein said first tubular member has an access hole to enable access to tighten said fasteners. ### Claim 8 A sealing arrangement for a pole assembly, said pole assembly comprising a base of substantially constant cross section, an upper mast of substantially smaller constant cross section and a cladding, a free end of said upper mast being inserted within a free end of said base so that a portion of said base overlaps said upper mast and said upper mast is fastened to said base, and said cladding surrounds said base, said sealing arrangement comprising a transition ring and a seal assembly, said transition ring surrounding a portion of said base and upper mast and said cladding at said free end of said base, said transition ring having an internal downwardly facing surface, and said seal assembly is disposed within said transition ring to seal between the external surface of said upper mast and said transition ring, said seal assembly comprising a sealing plate and a seal, said seal being disposed between said downwardly facing surface and said sealing plate, and the sealing action of said seal assembly is actuated by said sealing plate squeezing said seal. ### Claim 9 (depends on 8) A sealing arrangement for a pole assembly as claimed in claim 8, wherein said base comprises a plurality of first longitudinally extending channels that form corresponding longitudinal projections in its interior, and said upper mast comprises a plurality of second longitudinally extending channels, and wherein said longitudinal projections project into said second longitudinally extending channels, when said upper mast is inserted into said base. ### Claim 10 (depends on 9) A sealing arrangement for a pole assembly as claimed in claim 9, wherein said transition ring has a downwardly facing internal surface and a plurality of spaced apart steps, each step projecting into one of said second longitudinally extending channels from the bottom of a recess in said transition ring that open to the top of said transition ring, said downwardly facing surface including the underside of said steps. ### Claim 11 (depends on 8) A sealing arrangement for a pole assembly as claimed in claim 8, wherein a plurality of screws, each of which pass through said seal into said sealing plate, are used to actuate the sealing plate, and said screws are tightened from outside said transition ring. ### Claim 12 (depends on 8) A sealing arrangement for a pole assembly as claimed in claim 8, wherein said seal is made of a resilient material and shaped as a thin ring with a plurality of equispaced inwardly projecting tabs. ### Claim 13 (depends on 12) A sealing arrangement for a pole assembly as claimed in claim 12, wherein said sealing plate is made from a stiff material and has a shape similar to said seal. ### Claim 14 A sealing arrangement for a pole assembly, said pole assembly comprising a tubular base, a tubular upper mast of smaller diameter inserted within a free end of said base and fastened thereto, and cladding surrounding said base, and wherein said sealing arrangement comprises a transition ring and a seal assembly used to seal the transition between said base and said upper mast, said transition ring surrounding a portion of said base and upper mast and said cladding at said free end of said base, said transition ring having an internal downwardly facing surface, and said seal assembly is disposed within said transition ring to seal between the external surface of said upper mast and said transition ring, said seal assembly comprising a sealing plate and a seal, said seal being disposed between said downwardly facing surface and said sealing plate, and the sealing action of said seal assembly is actuated by said sealing plate squeezing said seal such that it bulges inwardly to seal between the external surface of said upper mast and said transition ring, and wherein the friction between said seal and the external surface of said upper mast keeps transition ring in position. ### Claim 15 (depends on 14) A sealing arrangement for a pole assembly as claimed in claim 14, wherein a plurality of screws, each of which pass through said seal into said sealing plate, are used to actuate the sealing plate to squeeze said seal, and wherein in use said seal and said sealing plate can be pre-assembled by fitting said plurality screws thereto, so that said sealing arrangement can be supplied ready to slide onto said upper mast, and final tightening of said screws is all that is required to complete fitting of said transition ring.
