FZ7020-27 40 km Video Link Test
The English PDF records a test between Wangwei Mountain and Majiawu on 23 December 2025. It includes environmental spectrum, test setup and bidirectional results at 20 MHz and 10 MHz bandwidth. All three pages are shown below.
The title describes two 0.5 W devices, whereas the setup and result tables record 800 mW / 29 dBm. The difference remains in the source report and is not treated as a single confirmed power setting.

Test Name: 40 km Video-Link Range Test Using Two 0.5 W Units Test Date: December 23, 2025 Test Locations: Wangweishan Mountain and Majiawu Viewing Platform Test Method: One module was installed at the summit of Wangweishan Mountain and connected to a computer via Ethernet. The other module was installed at Majiawu Viewing Platform and connected to another computer via Ethernet. After the link was established, bidirectional UDP traffic was generated between the two modules to measure real-time throughput. Spectrum of the Test Environment: Wangweishan Mountain elevation: 700 m; Majiawu Viewing Platform elevation: 200 m Test Configuration: Center frequency: 1360 MHz; transmit power: 800 mW; bandwidth: 20 MHz. A 2 dBi antenna was used at Wangweishan Mountain and a 5 dBi antenna at Majiawu Viewing Platform for the throughput test.
