1-1/4' feeder cable: A large-diameter, low-loss coaxial cable designed for high-power RF signal transmission over long distances. With its 1-1/4 inch diameter, it offers excellent shielding and very low attenuation, making it ideal for telecom base stations, broadcast towers, and large distributed antenna systems (DAS). Built with a rugged, weather-resistant construction, it ensures durable performance and stable signal integrity even in harsh outdoor conditions, meeting the demands of critical communication infrastructure.
