Long range fpv video transmitter

Types of long range FPV video transmitters

A long range FPV video transmitter is a device that sends video signals to the receiver from a camera on a drone or an unmanned aerial vehicle. It is designed to broadcast video signals over long distances for entertainment, commercial, or industrial purposes. FPV video transmitters are available in different types, each with unique features and functionalities.

The following are some of the types of long-range FPV video transmitters:

• Analog Transmitters

These are the most common transmitters and are compatible with most FPV systems. They have a simple design that makes them easy to use. They have lower latency, which is the time taken for the signal to be transmitted and received. Lower latency gives the pilot a real-time experience, and they can respond quickly to any obstacles in the way. Analog transmitters are also less expensive.

• Digital Transmitters

These transmitters convert the video signal into a digital format before transmitting it. The digital signal is less susceptible to interference from other devices, making it more reliable. Digital transmitters offer higher video quality compared to their analog counterparts. The images are sharper and clearer, allowing the pilot to see details of objects in the surroundings. However, digital transmitters are more costly.

• Adjustable Power Transmitters

They give the user the option to modify the power output. The power output affects the range and signal strength. The higher the power output, the longer the range. But this may not always be the case. The surroundings and obstacles in the way also determine the range. Adjustable power transmitters work well in places with many obstacles like buildings and trees. In such areas, the user can reduce the power output to improve the signal quality.

• Circular Polarized Transmitters

They use circular polarization to transmit signals. Circular polarization reduces signal loss and interference from other devices. The result is a clearer video signal. The receiver doesn't have to be precisely oriented to the transmitter. This makes the piloting experience more enjoyable. Circular polarized antennas are available in two types: left hand and right hand. The left-hand polarized antennas work with right-hand antennas and vice versa. They are commonly used in FPV systems.

Features and Functions

Long-range FPV video transmitters come with various features and functions that help their smooth operation. Some of the common features include;

• Power output: The power output of the long range video transmitter helps determine the range at which the video signal can be transmitted. The higher the power output, the longer the range, and vice versa. For example, a 1000mW (1W) video transmitter can transmit the video signal up to 3 miles, while a 200mW (0.2W) video transmitter can only transmit the signal up to 1 mile. However, it is important to note that different countries have restrictions on the maximum power output of video transmitters. As such, it is important to check and comply with the local regulations before using the transmitters.
• Video Format: Most long range fpv transmitters support different video formats, including PAL and NTSC. These video formats refer to the number of horizontal lines in the video resolution. PAL videos have 625 lines, while NTSC videos have 525 lines. In addition to this, PAL videos have a frame rate of 25 frames per second, while NTSC videos have a frame rate of 30 frames per second. The main difference between the two video formats is that PAL provides better resolution than NTSC. However, NTSC is preferred for fast-moving objects because it has a higher frame rate.
• Channel Frequency: Long-range fpv video transmitters come with different channel frequencies ranging from 5.8 GHz to 6.0 GHz. These channel frequencies are used to transmit the video signal from the drone to the receiver. Pilots can manually select the channel frequency using a button or switch on the transmitter. In addition to this, some transmitters come with a smart audio feature that allows pilots to change the channel frequency remotely using their radio controller. It is worth noting that each channel frequency has a specific frequency band, and it is important to choose a frequency that is not crowded to avoid interference.
• Integration: Some long range fpv transmitter and receiver come with an integrated camera and transmitter, while others are separate components that can be used together. Integrated video transmitters are more convenient as they are lightweight and easy to install. On the other hand, separate transmitters and cameras offer more flexibility as pilots can choose different cameras and transmitters based on their needs.
• Form factor: Form factor refers to the size and shape of the long range video transmitter. Common form factors include cylindrical, rectangular, and cuboid. The form factor of the transmitter is determined by its design and construction. For example, a long range fpv video transmitter and receiver that is built using a cylindrical case will have a cylindrical form factor. The form factor is important as it determines how the transmitter will be mounted on the drone. In addition to this, it also affects the weight and aerodynamics of the drone. As such, it is important to choose a form factor that is compatible with the drone.
• Mounting options: Mounting options refer to the different ways in which the long range video transmitter can be attached to the drone. Some transmitters come with a built-in mounting bracket that allows for easy attachment to the drone. Others may require custom mounting solutions, such as 3D printed mounts or adhesive tape. It is important to choose a mounting option that is secure and does not interfere with the operation of the drone.
