There are over 100 channels in the 5.8GHz frequency spectrum between analog and digital FPV systems (DJI FPV & Shark Byte). I included all these channels in a table and plotted a diagram so you can easily look them up and choose the best possible signal for video.
5.8GHz Channels Visual Chart
By knowing where the channels are located in the 5.8GHz frequency spectrum, the channel bandwidth, and how much separation there is between channels can help avoid video interference.
- 5.8GHz analog – 30MHz
- DJI FPV 25mbps – 20MHz
- DJI FPV 50mbps – 40Mhz
- Shark Byte – 27MHz
All Channels in Tables
The commonly used 5.8GHz analog bands are A, B, E, F and R. The other bands are rarely used but they do exist. Each band has a unique set of frequencies, individual frequencies may be repeated on other bands but the sets remain unique.
Analog FPV System
|Band||CH 1||CH 2||CH 3||CH 4||CH 5||CH 6||CH 7||CH 8|
Back in the days, the majority of video transmitter only supported 8 channels, and different brands would use different bands on their VTX’s. However modern VTX’s are now compatible with multiple bands, so that’s not something to be concerned about anymore.
- Band A: Team BlackSheep (TBS), RangeVideo, SpyHawk, FlyCamOne USA
- Band B: FlyCamOne Europe
- Band C (R): Raceband
- Band E: HobbyKing, Foxtech
- Band F (Airwave): ImmersionRC, Iftron
- Band D: Diatone
Digital FPV System
|Band||CH 1||CH 2||CH 3||CH 4||CH 5||CH 6||CH 7||CH 8|
|Shark Byte (FCC)||5660||5695||5735||5770||5805||5839||5878||5914|
|Shark Byte (CE)||5735||5770||5805||5839||-||-||-||-|
Tips and Best Practice
Choosing a channel
Although channels in a band are generally pretty well separated, the neighbouring channels could still be overlapping with each other and cause interference.
Raceband has the widest separation at 37MHz between channels and does not have any overlap, but this does not mean that Raceband can support all 8 pilots flying at the same time. We have to take “IMD frequencies” into account.
This article explains which are the best channels to use for FPV, and it also explains what IMD is.
Basically if you want multiple people flying at the same time, we cannot just rely on a single band, you should wisely choose from all available channels to achieve the best result.
You may also need to change your channel when flying with other pilots, in order to avoid interference from one another. Remember to be considerate, find out what VTX channels are being used before you power on your FPV drone. It can be hard to make friends at a flying field when people lost their best racing drone because you jumped on their video channel!
Making sure your VTX and VRX are on the same channel
You must ensure your 5.8GHz Video Transmitter (VTX) and the video receiver are operating on the same channel in order to establish a reliable video link. Some channels from different bands are very close to each other, just enough to getting a picture, but that doesn’t mean you are on the right channel.
Antenna and Placement
It is good practice to test your FPV setup before installing it in your craft, not only to confirm everything is working – but also because it can be difficult to access the buttons on the VTX once it is in the stack. We strongly advise you however, to structure your build so you CAN access the button and change your VTX settings. However this may not be so crucial if you are using Smart Audio or TRAMP – a way to change VTX settings through Betaflight OSD. Find out more about Smart VTX Control here.
Do not under power your VTX
Be aware that VTX have different operating voltages, a small VTX for TinyWhoop for example, will likely take 3V to 5V, where some have a wider operating voltage ranging from 7V to 24V. You might be able to power a 7V VTX with 5V, but performance (range) could be hugely impacted.
Interference work around / troubleshoot
It is uncommon, but you may occasionally experience atmospheric interference, to combat this try using remote channels like E4 and E8, or another combination that offers a wide gap between frequencies. Some interference might be power related, see here for a more detailed article on fixing FPV video issues
Conflicts with WiFi
5.8GHz WiFi signal uses frequency between 5170MHz – 5835MHz, this could interfere with our FPV signal. You might experience noisy or loss of signal when flying near populated residential and business areas, where there is WiFi signals around.
It’s best to use a channel as far away from this band as possible, for example Raceband 8 (5917MHz) would be a good option.
In fact, your VTX can affect WiFi signal too, and your 1W VTX’s can be great WiFi jammers :) If your home WiFi drops out while you are working on your quad, it’s likely to be caused by the VTX. If this happens, simply move your channel to a higher frequency.
Not All 5.8Ghz Channels are Legal!
Although there are many channels and power level available from VTX these days, you should always find out what is allowed in your country before transmitting. Many places restrict 5.8GHz output power to 25mW unless the user has a license.
5.8GHz FPV bands like “L”, “U” and “O” fall entirely outside the legal frequency allocation in the US and Europe, making them illegal to use (and possibly many other countries too). That’s why you won’t see VTX with these channels when you buy from legit RC shops.
Not to mention these bands are much lower than the standard 5.8Ghz bands, and your antennas are probably not precisely tuned for those low frequencies. My advice is to stay away from VTX’s that offer these illegal frequencies, honestly a VTX that has 40 or 48 channels is more than enough.
