RG303 is a High-Power Handling, Ultra Low Loss, Indoor/Outdoor, Silver-Plated Coaxial cable.
The RG303 has excellent attenuation stability. The silver-plated outer conductors prevent oxidation of the conductors thereby minimizing attenuation change vs time. Conversely, bare copper outer conductors may oxidize quite rapidly precipitating loss increase.
High Temperature Handling, Unsurpassed flexibility and bendability are advantageous features of the cable design.
The mechanical properties of the cable such as the solid dielectric provides superior crush resistance and therefore is well suited for tactical applications.
RG303 coaxial cables are designed for outdoor exposure incorporate FEP jackets for UV resistance. The FEP jacket is also chemically inert, this means it has excellent resistance to corrosive fuels, chemicals and oils.
There are a wide variety of connectors available for this cable, including all common interface types.
