Attaining the desired drone GHz range is a lifelong goal for all drone pilots. This makes it important for drone pilots to understand concepts such as antenna selection, RF theory, and design if they are to maximize their experience. The average 2.4GHz drone is two and a half times better than the 5.8GHz drone because of the theoretical range. Doing something as small as changing the antenna of your drone can improve the range by up 33km.

Drones that have a smaller range can be annoying but the good news is that you can increase the range even if you are not an expert. Drones have different range values depending on which one you buy, but it is imperative to know how to maximize it.

Factors That Influence the Drone GHz and How to Make the Most of It

As far as the highest range of your drone is concerned, certain factors affect it. The factors include the following:

  1. Frequency used
  2. Transmitter power
  3. The positioning of the drone and control
  4. Interference from other RF sources
  5. Reflective obstacles

The frequency

The drone GHz is a vital factor that determines the range. The relationship between the range of the drone and the frequency is inverse. This means that the longer the range, the lower the frequency. When choosing the frequency, you should know that unless you find yourself in an environment of higher interference within the 2.4GHz band, going for the 5.8GHz option won't be the best for you. Note that 5.8GHz will give you 50 percent of the range of 2.4GHz.

Transmitter Power

The higher the power of your drone, the higher the range will be. The range has a direct proportionality with the square foot of the power. What this implies is that when you double your power, you will be able to increase the range of the drone by up to 40%. Even though you may not get a very significant boost in range, it is worth it. 

The positioning of the control and the drone

Without a doubt, if there is an obstacle lying in the line of sight of the drone and control, there will be a drop in signal. This extends to obstacles that may not be in the line of sight of the drone as well. All obstacles that lie within the Fresnel zone will affect the drone range. The Fresnel zone refers to an area that looks like a rugby ball and lies between the receiver and transmitter. If you are looking to achieve the best link, make sure this area is devoid of obstacles.

If you notice that your drone GHz strength becomes lower, you may have to fly higher and escape the Fresnel zone.

Interference from RF sources

Another factor that could affect your drone GHz range is the interference that emanates from other RF sources. There are three distinct factors you need to consider in this regard. Note that it is interference if it is within your frequency. Also, it is only interference if it lies within the radiation pattern of your drone which means that if you are using a high gain antenna, it won't matter as long as you have interference behind you. Finally, it is a problem if you have interference that is more than the power of your transmitter.

For instance, if you are using a directional antenna, and you lift off from a place outside of town. You begin flying and gaining altitude even as you get closer to town without difficulties, you start descending and lose signal. The real reason for such a situation is that you are closer to the houses in town and a strong interference came up with the radiation pattern of your antenna. So, to increase your range, ensure you stay away from interferences from RF sources.

Reflective Obstacles

You need to be conscious of the place you have your ground station set up and you need to know if you will be dealing with reflective interference. Multipath is a real issue that happens when the signal gets to the receiver from different directions. It usually occurs when there is a bounce off of the signal from obstacles. Make sure you do not set your station up close to large obstacles.

Final Note

Getting the best out of your drone GHz is a task that isn't exactly rocket science. More often than not, the range of a drone is subject to external factors that could get managed by whosoever is piloting the drone. You may be in a hurry to read through the factors outlined in this piece, but understanding them will save you a lot of time and money!
