5. Parameter Settings
Frequency: 1410MHz
Bandwidth: 10MHz
6. Test Plan
Distance (between A and B) measured on Google Map is 42.06km
1) The Ground Tracking Unit uses a 14dBi directional antenna and a 6dBi omnidirectional antenna, while the Air Unit uses a 5dBi omnidirectional antenna. Point A is where the computer and Ground Tracking are placed, and Point B is the top of Shenzhen South Mountain, where the Air Unit is installed. The Ground Tracking Unit is mounted on a tripod.
2) The Ground Tracking Unit uses two 5dBi omnidirectional antennas, while the Air Unit uses a 5dBi omnidirectional antenna.

8. Conclusion:
1) Comparing directional antenna and omnidirectional antenna, directional antenna offers significantly higher bandwidth and better signal quality. It can increase bandwidth and signal strength by approximately 20%.
2) From the perspective of device power output comparison: The power output of the Air Unit has a more significant impact. The bandwidth difference between 4W and 20W can exceed 6Mpbs. For the Ground Unit, the difference between 4W and 20W is relatively smaller, with a difference of only about 1-2Mbps.
