Shortwave Sector Broadband Antenna
Product Overview
This series of Shortwave Sector Broadband Antennas is developed based on classical shortwave antenna design theory and optimized through extensive simulation and testing. The antenna features biconical dipole elements, providing smooth impedance, low matching loss, and higher gain than conventional linear or planar dipole broadband antennas. The elements are made of 7×7 strands of tinned copper wire coated with high-temperature resistant silicone rubber, ensuring corrosion and rust resistance while enhancing long-term communication reliability. This antenna series has successfully been developed into vehicle-mounted portable versions, with setup or takedown time under 12 minutes, making it particularly suitable for mobile communication in harsh electromagnetic environments.
