Our newest material has been created for the 5G, SATCOM, and telecommunications industries. ProDome is designed to maximize the performance of antennas and other RF components.

ProDome Applications
– Radomes
– Sensor Covers
– Dielectric Covers
– Antenna Masts

ProDome utilizes the natural UV resistance and hydrophobic properties of a fluoropolymer membrane that is chemically bonded to the composite’s surface. The membrane also prevents chipping, tearing, UV degradation, and water absorption, all with a dielectric performance that rivals thermoplastics.

Our composite configurations are stronger than many injection molded components, and we offer a variety of grades to meet your application. Our standard grades come in sheets and molded forms.
