Sinclair’s Comshel© (communications shelter) as shown in Figures 3-6 and 3-7, has been used for
many years to shelter communications systems from hostile environments in remote locations and is
ideal for use at high altitudes, and in extreme conditions. It has proven itself able to withstand strong
winds and a build up of radial ice.
The basic composition of the comshel is fi berglass roving with cloth and mat as reinforcement for a
thermoset resin. Depending on specifi c needs, the resin can contain fi re-retardant additives and ultra-
violet inhibitors. The base section includes a layer of polyurethane foam that provides excellent thermal
insulation and adds to the strength of the structure. The comshel has a smooth gel-coat surface and
round design that sheds ice, and rock anchors that help withstand high winds.
