The more powerful the video transmitter, the more drain on your battery.ДЄlso, depending on where you are living, a more powerful transmitter may have an effect on other devices nearby as well as receiving interference from other devices, which may both the video signal from your drone or to the drones GPS navigational system. So if a 200 milliwatt transmitter gives a 1.5 mile video transmission range, then you would need an 800 milliwatt transmitter to double the live video range. However, to double the range, you would need to quadruple the power. You could decide to use a more powerful FPV transmitter and receiver. For example you want to receive live FPV video transmission from your UAV from 3 miles (4.8 km). Now, supposing you want to receive live video transmission further than 1.5 mile (2.4 km). Using the above omnidirectional transmitter and corresponding antenna will give a live video signal up to about 1.5 mile (2.4 km) range. The video quality will become grainy or you will lose video as the receiver and transmitter move away from each other. How far away, you receive video signal depends on the transmitter and receiver your are using. Now, if you have a corresponding circularly polarized omnidirectional receiver antenna, then you can receive FPV video signal more or less equally in any direction from the FPV transmitter. The radiation pattern is pretty much a circle or omnidirectional which is an equal amount of strength in all directions.

If you can picture the above video transmitter with antenna in the middle of a balloon, then the radiation which comes out of the antenna spreads out in all directions.

In radio communication, an omnidirectionalВ antenna is a class of antenna which radiates radio wave power uniformly in all directions in one plane, with the radiated power decreasing with elevation angle above or below the plane, dropping to zero on the antennaвЂ™s axis.В ThisВ radiation patternВ is often described as sphere or doughnut shaped. If you have an FPV transmitter like in the above photo which is a 200 milliwatt, 5.8 GHz, 40 channel video transmitter, it produces an omnidirectional radiation pattern from itвЂ™s circularly polarized antenna. Drone FPV (First Person View) signals or live video transmitter signals are no different. Radio frequencies always need an antenna to transmit and receive radio signals.

This post will assist you in learning about live video transmission, radio frequencies, omnidirectional and directional antennas and how to increase the FPV range from any drone. If you want to build and design drones, then understanding drone live video using radio frequencies, transmitters and receiver signalling technology is essential. However, understanding the UAVвЂ™s live video transmission technology will help you if you want to increase the live video range from your drone or troubleshoot video transmitter and receiver problems. To fly a drone, you donвЂ™t need to understand the technology behind it all, as drones have become so easy to fly.

If you are using top FPV goggles, it feels as if you are in the drone. It is a terrific flying experience as you are seeing what the drone camera sees. This live video transmission, along with high quality cameras, allow drones to be used in many positive ways across numerous sectors. FPV live video using radio frequency antenna, transmitter and receiver signaling technology is one of the main reasons why drones have become so popular.
