- System advantage:
Faster Measurement：the symmetrical distribution of probes is applied. Thus, the object can be 3D measured completely as long as a
180-degree rotation is performed horizontally under normal circumstances.
Real-time display：It allows real-time viewing of passive directivity diagram as well as sensitivity.
Powerful function: It supports the passive measurement within the frequency range between 400MHz and 6GHz. It can support the
measurement of large antenna, especially suitable for BTS antenna measurement.
