The AHA118D 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 wideband communication and can be ideally used in multiple applications like mobile communication, countermeasures, monitoring, jamming and military applications. The AHA118D is made with military-grade aluminium to withstand even the harshest of environments.

 

The AHA118D is providing maximum propagation directionally on all frequencies between 1GHz and 18GHz in two linear polarization.

The broadband horn antenna AHA118D offers a low VSWR in its 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 AHA118D horn is suitable for both transmission and receiving applications. The maximum handling power is only limited by the female N-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 AHA118D is made in the United Kingdom with domestic and imported components and includes a one-year warranty period—patent pending.
