380 MHz - 12 GHz Ultra-Wideband Spring Antenna

KGN3M8-12G0-2.5V-HP

The KANTENNAS KGN3M8-12G0-2.5V-HP is an advanced, ultra-wideband, high-power omnidirectional antenna designed for demanding RF applications, including defence communications, counter-UAS systems, RF spectrum monitoring, electronic support, passive RF detection, and specialized wireless systems.

Operating continuously from 380 MHz to 12 GHz, this broadband antenna provides exceptional frequency coverage across UHF, L-band, S-band, C-band, and X-band frequencies. Its wide operating bandwidth makes it particularly suitable for multiband RF systems requiring a single antenna solution for transmitting and receiving signals across a broad frequency spectrum.

The antenna features a rugged, spring-mounted mechanical configuration designed to provide flexibility and accommodate movement in portable, mobile, and fixed RF installations. The integrated spring assembly helps reduce mechanical stress caused by movement and incidental impacts, making it suitable for applications where rigid antenna mounting may be less desirable.

Featuring vertical polarization and omnidirectional azimuth coverage, the KGN3M8-12G0-2.5V-HP is designed to provide 360-degree horizontal RF coverage without requiring directional antenna alignment. This makes it particularly useful for wideband RF receivers, spectrum monitoring equipment, electronic support systems, and passive RF sensing platforms.
