ULL400&trade; Ultra Low Loss Coaxial Cable with N-Male Connectors 25 Feet (ULL400-NM-NM-25FT) Coaxial cables are critically important in any RF system, especially booster, amplifier, and repeater systems, which are usually employed in low-signal areas. Using cables that are too thin or with improper impedance can have catastrophic consequences in such systems, especially if the required cable run is above 25 feet. Because of the very high frequencies employed by many service providers, we always recommend WirEng&reg; ULL400&reg; coaxial cables with any booster/amplifier/repeater system. The ULL400&trade; cable series also features ultra-low loss, top quality connectors so that the signal kept strong by the cable is not negatively affected at the extremities! The ULL400&trade; cables can be used from DC to 6,000MHz and are therefore suitable not only for all GSM/CDMA/TDMA/Cellular/DCS/PCS/AWS/XLTE/4GLTE/WiMAX bands, but also with all Wi-Fi standards currently available! The ULL400-NM-NM-25FT operating frequency range is DC-6000 MHz, with nominal impedance of 50 Ohm. The connectors are N Male/N Male. The ULL400-NM-NM-25FT is mainly recommended for indoor/outdoor/underground applications. The ULL400-NM-NM-25FT measures 300 x 0.5 x 0.5 inches and weighs 2 lbs. Made in the USA with skilled craftsmanship. One year manufacturer warranty included.
