UHF Plug (Male) to 7/16 Jack (Female) Adapter | Straight | Brass Body
The ROSNOL AD-U1D25A/H44‑H4 is a UHF plug (male) to 7/16 jack (female) straight adapter engineered for rugged RF applications from DC to 1 GHz. Supporting 50 Ω impedance, insertion loss ≤ 0.2 × √F(GHz), insulation resistance ≥ 5 GΩ, and power handling up to 250 W, it provides a stable transition between UHF and 7/16 interfaces for high‑power and low‑frequency communication systems.
The adapter uses phosphor‑bronze center contacts with gold plating over a non‑magnetic nickel‑phosphorus underlayer and a brass body with copper–tin–zinc alloy plating for structural reliability. PTFE dielectric insulation maintains stable electrical characteristics. Both ends employ screw‑lock coupling, with ≥ 500 mating cycles and coupling‑nut retention ≥ 1000 N for mechanically demanding RF environments.
ROSNOL leverages extensive RF engineering expertise, advanced inspection systems, and controlled material processing to deliver high‑power adapters suitable for communication towers, industrial RF systems, and infrastructure‑grade equipment. Manufactured in ISO 9001‑certified facilities and fully RoHS/REACH compliant, ROSNOL products offer high durability and technical value at competitive pricing. Customers benefit from wide customization capabilities, including unique inter‑series transitions, reinforced mechanical structures, special plating options, and application‑specific RF performance tuning.
