Shortwave Umbrella-cone Broadband Antenna
Product Overview
The Shortwave Umbrella-Cone Broadband Antenna is a typical shortwave vertically polarized broadband antenna. By thickening the elements to smooth impedance, the antenna extends its operating bandwidth. The carefully designed umbrella-cone structure prevents the absorption of radiated energy caused by excessively low thickening positions, achieving the highest radiation performance among similar vertically polarized antennas. The antenna body is made of high-quality cold-drawn metal tubes and hot-dip galvanized for structural stability, reliability, and excellent conductivity. Designed for maintenance-free operation, it is an ideal choice for building various shortwave omnidirectional communication networks or jamming stations.
