Test Steps:

1. Set up the vertically polarized transmitting antenna and the antenna under test (AUT).

2. Rotate the AUT (0-360°). The MI-3003 Arena test system automatically records the full-range amplitude at each frequency point.

3. Set up the standard antenna and repeat step 2.

4. Export the test data and record the signal levels of the AUT (G1) and the standard antenna (G2). G0 = G1 – G2 + Gain of Standard Antenna (gain of the AUT at that frequency point).
