| 摘要 |
The invention related to a polyurethane foam panel which is substantially RF-transparent from 0 MHz to 100,000 MHz, & OMNI antennas and which can be camouflaged by application of paint and other coatings to match the exterior surfaces of buildings, rooftops, exterior walks, silos, flagpoles, steeples, and other structures on which such antennas may be installed. These foam panels are used to form an inexpensive, safe, efficient, structurally sound method to camouflage cellular, PCS, RADOM & OMNI, and other antennas.
