Introduction
In previous posts I have tested the various HF & VHF antennas that I have using the versatile NanoVNA (Ref.4/5/6). In the last post I decided to try pushing the NanoVNA beyond it’s spec of 1.5GHz to test my Inmarsat Patch antenna (Ref.1). In this post I will test the L band microwave dish that I successfully used to decode GOES16, the Hydrogen line and Inmarsat (Ref.2).
Test Results
Figure 1 shows the test setup to determine frequency/power output of the NanoVNA. Figure 2 & 3 shows the S11/SWR/CW output at 1, 1.5, 1.8 and 2GHz. Figure 4 shows the L Band Dish Antenna response from 1 – 1.8GHz. Note the good match at 1694MHz for the GOES16 signal.
