How To Connect FPV Transmitters with FPV Goggles

Frequencies? Bands? How do I find the right channel for my goggles? Here’s some info to help you out.

If you’re fairly new to the world of FPV (First Person View) flying, frequency band charts can be very confusing. This is an article to simplify everything. Today, we’ll be focusing on the popular FPV frequency of 5.8GHZ. For information on other frequencies, check out this Flite Test article.

Bands

Each band has a unique set of frequencies. These are the lettered categories that different manufacturers use. Team Black Sheep gear might use Band A whilst Fatshark gear might use Band F. Within each of these bands, there are usually 8 separate channels.

Band	Frequency Ch1	Frequency Ch2	Frequency Ch3	Frequency Ch4	Frequency Ch5	Frequency Ch6	Frequency Ch7	Frequency Ch8
A	5865	5845	5825	5805	5785	5765	5745	4725
B	5733	5752	5771	5790	5809	5828	5847	5866
C	5705	5685	5665	5645	5885	5905	5925	5945
F	5740	5760	5780	5800	5820	5840	5860	5880

You can select the frequency band that you’d like to use on your video transmitter by clicking a button or flipping a dip switch. This is usually marked 'FR'.

Next you can select the channel within the band, again by pressing a button or flipping a dip switch on the transmitter. This is usually marked 'CH'.

The numbers on this transmitter correspond to those on the FPV frequency band table. For example, the display shows ‘4’ and ‘1’ which refers to the frequency band ‘4’ (also known as ‘F’), channel ‘1'.

Selecting a channel on your receiver/goggles

When you get a pair of video goggles, they should come supplied with a list of frequencies that the receiver can connect to. Often you can also find this information online along with which specific band the goggles use.

Occasionally, the manual that comes with your receiver/goggles might not explicitly reference which band it works with. Instead, it might come with a list of channel frequencies like this:

CH1: 5740 MHz CH2: 5760 MHz CH3: 5780 MHz CH4: 5800 MHz CH5: 5820 MHz CH6: 5840 MHz CH7: 5860 MHz

That’s quite alright though. All you’d have to do in this instance is see which numbers marry up with the numbers on the band chart: ‘CH1: 5740’ can be found in band F, so you’ll know to select that band and channel on your transmitter. Simple.
