Description
UHF Plug (Male) to Type C Jack (Female) | Straight Design | Screw-Lock & Bayonet-Lock | Brass Body
The ROSNOL AD-U1C25A/H44-H4 is a precision RF adapter designed for systems operating from DC to 300 MHz with 50 Ω impedance. It delivers VSWR ≤1.15 (≥23.13 dB return loss) and insertion loss ≤0.04√F (GHz) dB for excellent signal integrity. Coupling mechanisms include screw-lock on the UHF side and bayonet-lock on the Type C side, ensuring secure engagement and mechanical durability with ≥500 mating cycles.The center contacts are phosphor bronze with gold plating over nickel underplating for superior conductivity and corrosion resistance. Bodies and coupling nuts are brass with copper-tin-zinc alloy finish, while insulators are PTFE for excellent dielectric properties. A silicone rubber gasket enhances environmental sealing. Operating temperature ranges from -65°C to +165°C for dependable performance in harsh conditions.
ROSNOL’s precision-engineered RF adapters deliver consistent performance across high-frequency applications. Manufactured in ISO 9001-certified facilities and fully compliant with RoHS and REACH, they provide a cost-effective alternative to leading European and American brands. Customization for materials, plating, and mechanical design is available to meet specialized requirements.
