The bottom line: this cable is for installers and hobbyists who must move signals across long distances with minimal degradation - its reported loss of under 7.2 dB at 900 MHz and SWR near 1.15 make it a practical choice for cell signal boosters, WiFi repeaters and ham radio feeds where a durable, weatherproof line is required.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra low loss:\u003c\/strong\u003e The cable keeps signal loss to under 7.2 dB at 900 MHz, helping preserve RF power over a 200 ft run.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow SWR:\u003c\/strong\u003e A reported SWR of about 1.15 reduces reflections and improves matching for many 50 ohm systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable conductors:\u003c\/strong\u003e The inner copper-clad aluminum conductor and aluminum-magnesium braid provide a balance of conductivity and mechanical strength for long-term use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeatherproof jacket:\u003c\/strong\u003e A PVC outer jacket enables indoor or outdoor routing and holds up in harsher environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide compatibility:\u003c\/strong\u003e Works with any 50 ohm RF system and accepts common connector types such as UHF, SMA, BNC, TNC and N when fitted.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis cable is aimed at installers, amateur radio operators and anyone fitting signal boosters or long antenna runs who needs a consistent 50 ohm feed over 200 ft.
