TCI Manufactures High-Performance ETFE film that can be bonded/laminated to a composite core to protect antennas. The film is formulated to protect high-performance antennas in the most challenging environments. Its superior mechanical properties, low dielectric constant and permanent hydrophobic surface provide excellent RF performance across multiple frequencies. The films are surface treated to ensure excellent bonding to structural elements. The opaque UV blocking formulation of the material protects the integrity of the film / composite interface.
