Two way radio with antenna extension is a high-performance communication device developed by Quanzhou Kaili Electronics Co., Ltd. that includes a detachable or extendable antenna to enhance signal range and transmission quality. Manufactured in a 12,000-square-meter standard factory with advanced production lines and imported testing instruments, this feature addresses the limitation of fixed antennas by allowing users to replace or extend the antenna, thereby increasing communication distance by up to 50% in some cases. The antenna extension is typically made from high-quality materials like copper or stainless steel, designed to optimize signal propagation across UHF or VHF frequencies. It is easy to attach, with a secure connector that ensures a stable connection to the radio. This two way radio offers a base range of 2 to 8 kilometers, which can be extended to 3 to 12 kilometers with the antenna extension, making it suitable for use in large areas with obstacles, such as rural landscapes, industrial complexes, or outdoor events. The device features a durable design, with options for weatherproofing (IP54/IP67) to withstand outdoor conditions, and a long-lasting battery supporting 8 to 20 hours of operation. Additional features include clear audio transmission, multiple channels, and compatibility with other accessories like headsets. Two way radio with antenna extension is widely used by professionals in fields like search and rescue, agriculture, and event management, where extended range is critical. By offering this customizable solution, Quanzhou Kaili Electronics embodies its "quality win" philosophy, providing users with the flexibility to adapt their communication tools to specific environment needs.
