ZDTECH ZD03820/45 Planar Helical Antenna is a high-performance wideband communication device, operating in the 0.38-2GHz frequency band, perfectly meeting the needs of various wideband communication scenarios. Adopting right-hand circular polarization design, the antenna has a VSWR ≤2.5, ensuring stable and efficient signal transmission. The gain is ≥-13dBi within ±45° in both azimuth and elevation, and the 3dB beamwidth flexibly adapts from 62° to 106° with the frequency band, delivering excellent directional performance.
Crafted from high-quality aluminum alloy, the product features a military green finish that combines durability and recognition. With an overall size of 180mm×180mm×95mm (±2mm, excluding connector and mounting structure) and a weight ≤650g, its lightweight design facilitates easy installation and deployment. Equipped with a standard SMA-K connector, it offers strong compatibility. Meanwhile, it boasts outstanding environmental adaptability, with an operating temperature range of -90°C to +55°C and a storage temperature range of -90°C to +70°C, capable of coping with extreme weather conditions and providing stable and reliable signal support for communication systems.
