A system having a hidden external communication element, the system comprising: an external communication element, wherein the external communication element comprises at least one antenna, a radio, and a small cell antenna, and a film (200) multilayer non-metallic polymer optics formed into a shape that at least partially surrounds the communications element and hides it from view, characterized in that the multilayer optical film (200) comprises a core layer (202) comprising a multilayer optical stack comprising two alternating polymeric layers, wherein the polymeric multilayer optical film (200) further comprises a UV stable protective layer (204) placed between an observer looking at the system and the, the protective layer comprising one or more absorbents of UV, wherein the substantially specular polymer multilayer optical film (200) reflects images of the surroundings of the system to an observer who is looking to the system, where the specular reflectivity of the polymer multilayer optical film (200) is greater than 80%, where the diffuse component of the reflectivity does not exceed 20%, and where the polymer multilayer optical film (200) is greater than 90% transmissive radio frequencies in the band in which the communication elements receive and / or transmit. |
