ClearBoost - Enhanced 5.8GHz Video Reception

Adding ClearBoost to your receiver enhances and boosts your incoming signal to display a clearer video with more range.

The style of RF connector to plug your ClearBoost into your Video Receiver. The SMA type should match your video receiver's antenna port. Right angle is recommend for Fat Shark goggles, straight for a typical receiver setup.

Ultimate Video Performance!

Adding ClearBoost to your video receiver gives you increased flight flexibility. Where before you received a weak signal, the ClearBoost bumps it up from static to clear video. Whether you are flying long distance aerial mapping, or FPV racing around trees and obstacles, ClearBoost is going to give you more consistent video.

If you have tried a high gain antenna, such as a heilcal or patch antenna, you have seen the benefits increase gain yet also the limitations of a narrow beamwidth. ClearBoost offers you the same signal gain, but allows you to use any antenna, with any beamwidth!

Product in Brief

New antennas designs and availability have revolutionised the FPV and sUAS industry by providing a tailored solution specific to the needs of pilots, rather than utilising WiFi and other-purpose products for the job. Now, we take things to the next step in the evolution of flawless flight video. By adding ClearBoost to your receiver, you can see the same performance gain as adding a high gain directional antenna, yet continue using your existing antennas.

We still use analog video for flight because it offers the lowest latency but that doesn't mean you should be stuck looking at a noisy, static filled image any time you fly behind something or get too far away. ClearBoost will give you cleaner clearer video when you signal gets too weak for your reciever to properly handle, the same as a directional antenna would. Don't be limited to a single flight direction, use an omni-directional antenna and fly anywhere.

Use With Certified Modules

For pilots in countries that require the use of a 25mW or less certified transmitter module, ClearBoost gives you the same RF Link Budget (total combined signal strength of your antennas, receiver sensitivity, and transmitter power) as using a 600mW video transmitter without it. If you live in Europe, or fly at racing events in the USA or Canada - then ClearBoost offers you a clear advantage by giving you far more signal.

How Does it Work?

Your video transmitter radiates energy in the form of radio waves, on the ground these are picked up by your antenna and then passed into your video receiver. The video receiver then converts this signal back into a video picture... hopefully pretty similar to what went into the transmitter.

If something gets in the way of that signal, even just air, the video picture starts to look fuzzy or broken. Flying behind something like a tree can instantly ruin your day by reducing the signal so much the receiver can no longer make an understandable video picture out of it.

The solution to this is simply more power, on one end or the other. A more powerful transmitter sends out a more powerful signal, however this isn't as viable as it might sound. Going from a 0.5 Watt  (500mW) transmitter to a 2 Watt transmitter might sound like a lot, with four times the power, but it is really only 6dBm (the units RF power is measured in) - as decibels are logarithmic this means you only get twice the signal strength from four times the power! Increasing transmitter power offers rapidly diminishing returns so instead you must look at the other end of the RF equation, the receiver.

Furthermore, in many countries (all of Europe for example) regulations limit you to just 25mW of power. In these regions, using a more powerful transmitter is not an option at all - so any signal enhancement must be done on the ground.

So far in the FPV/Drone world the best choice is a high gain antenna attached to your receiver. A typical high gain 5.8GHz antenna from the well known brands gives you around 13dB of gain - about the same as going from 0.5 Watts to 10 Watts on the transmitter side! However there is a downside, you can now only fly where the antenna is pointing.  We love the Circular Wireless Helical, but with just 11dB of gain and a beam width of 60 degrees we lose 300 degrees of flight options horizontally and have to watch our flight altitude. Note that many directional antennas are mid gain, around 7-9dB. With 4-6dB less gain that the high gain antenna, or ClearBoost, they offer one third to half as much signal strength.

ClearBoost provides electrical amplification of the signal on the receiver side. Adding 13dB of gain to such a weak signal as received by your antenna consumes just 18-20mA of power - about 1/10th of what your receiver is using. Its about the same as using a 10Watt transmitter (assuming you started with 600mW) on your aircraft, or using a high gain directional antenna on your receiver, but without the limitations in flight direction or smoking hot transmitters.

Technical Specifications

ClearBoost runs off a wide range of voltages, which makes it easy to integrate with your existing ground station. Anything from 4 to 17 volts (a UBEC or 2-4 LiPo cells) will happily power the device and draw just 20mA. There is extensive power filtering in the device to deal with any power fluctuations/quality issues that other devices in your ground station generate.

  • Gain 14.7dB at 5000MHz, 13.8dB at 6000MHz
  • Voltage 4-17V
  • Current 18.5mA
