Astro Horn Antenna 4-40GHz (AHA440D) - Dual Polarized 

The AHA440D by AstroAntenna® is an industrial/military strength directional antenna and can be used as a reference test antenna in the laboratory. The antenna is highly suited for modern and upcoming 5Gs and can be ideally used in multiple applications like countermeasures, monitoring, jamming, medical and military applications. The AHA440D is made with the military-grade aluminium to withstand even the harshest of environments.

The AHA440D is providing maximum propagation directionally on all frequencies between 4GHz and 40GHz in two linear polarization.

The broadband horn antenna AHA440D offer a low VSWR in their nominal frequency range and very broad bandwidth. The gain increases with frequency up to approx. 16 dBi, The increasing gain with frequency helps to compensate for cable losses. The AHA440D horn is suitable for both, transmission and receiving applications. The max. allowed Input Power is only limited by the female K-connector. The detailed manual of the calibrated test antennas includes Gain, Antenna Factor, VSWR and Directional Patterns. 


The back structure mounting section allows easy adjustment for vertical, horizontal and 45 deg polarizations.

The AHA440D is made in the United Kingdom with domestic and imported components and includes a one-year warranty period. Patent pending.
