HT8 Ultra-Wideband Log-Periodic Directional Antenna 100M-12GHz UAV Detection PCB Directional Antenna for Signal Direction Finding and Spectrum Analysis

The HT8 Ultra-Wideband Log-Periodic Directional Antenna is a high-performance RF front-end component designed specifically for low-altitude security and electromagnetic environment monitoring. As the core directional antenna for drone detection PCBs, it operates across 100MHz to 12 GHz, seamlessly capturing full-band signals ranging from traditional remote control links to modern 5G/WiFi video transmission systems. Built with lightweight PCB microstrip technology, this antenna delivers excellent directivity and high gain (7-12 dBi), making it ideal for drone signal direction finding, broadband spectrum scanning, and precise EMI/EMC measurements. Supporting both horizontal and vertical polarization switching, the HT8 features standard mounting holes at the rear. It can be used independently as a handheld unit or integrated as a feed source into parabolic reflectors or SA6 systems to enhance long-range detection capabilities. With its low VSWR and suppressed sidelobe levels, the HT8 effectively mitigates environmental clutter interference, significantly improving the signal-to-noise ratio and positioning accuracy of radio reconnaissance systems—making it the ideal choice for building high-precision drone early warning networks.
