Harogic HDA-100 active directional antenna
Details
The Harogic HDA-100 is a cost-effective active directional antenna and is suitable for spectrum monitoring, interference hunting and signal direction finding at a frequency range from 500MHz to 10GHz. Furthermore, this antenna pairs a directional element with a switchable amplifier, so weak signals can be lifted by 20dB where needed, and the amplifier can be bypassed when a strong signal would otherwise overload the receiver.
An integrated attitude and heading reference system reports azimuth, pitch and roll in real time, so the direction of every measurement is recorded alongside the signal. The antenna is powered over USB-C by the host, which keeps the assembly light at 680g and removes the need for batteries. When used with a Harogic spectrum analyser, the antenna factor is loaded automatically in SAStudio4, where the mapping mode plots measurement points and colours them by received signal strength. The software interface shows the operational status of both the antenna and amplifier, providing real-time monitoring and enhancing ease of use.
