According to your transmission distance, 10km, 30km, 80km, 150km, Choose the suitable power amplifier 0.3 ວັດ, 2 ວັດ, 5 watts and 10 ວັດ, to ensure how far the video signal can travel and how well it can penetrate obstacles. Higher power means longer range and better penetration, but also more interference with other signals and more battery consumption.

The wavelength of the video signal and how it interacts with the environment are determined by the frequency of the transmitter. Lower frequencies have longer wavelengths and higher penetration, but they also have more interference and less bandwidth. Higher frequencies have shorter wavelengths and less penetration, but they also have less interference and higher bandwidth. The transmitter's frequency range is from 800 MHz to 1.2G, 2.4G, ຫຼື 5.8 GHz.

The size and weight of the transmitter have an impact on the drone's aerodynamics and performance. Smaller and lighter transmitters are easier to mount and have less influence on the flight characteristics of the drone, but they may have less power and features. Although larger and heavier transmitters have more power and functionality, they also take up more space and add weight to the drone.

Some transmitters include extra features that improve their functionality and usefulness. Some transmitters, ຍົກ​ຕົວ​ຢ່າງ, include a built-in speaker that allows the operator to play a warning or broadcast from the drone's surroundings. Some transmitters have radio telemetry, which allows the user to adjust transmitter settings remotely using their radio controller or control the drone to conduct drop or launch activities.
