DJI RC Plus 2 sub2G SDR Module
A rear-mounted expansion module that adds 902-928MHz and 1.4GHz transmission bands to the RC Plus 2 Enterprise Enhanced, on top of its standard frequencies. Lower frequencies penetrate buildings, terrain, and foliage more effectively than higher ones, extending genuinely reliable command and control range in the environments that cause the most dropped connections.
Important: Regulatory Authorisation Required
Sub-2GHz operation is only usable with the appropriate radio licence and authorisation from your local regulatory authority. This isn't a plug-in-and-go feature everywhere, permitted frequencies and power limits vary by country. Confirm your specific authorisation with Ofcom or your local regulator before relying on this module operationally, and our team can point you toward the right starting point.
Why Lower Frequencies Matter
Standard O4 transmission performs well in open, unobstructed conditions, but higher frequencies lose strength faster when passing through solid obstacles. Shifting part of the link down to sub-2GHz bands keeps the connection more stable in exactly the conditions that break it: dense urban environments, wooded terrain, and industrial sites with heavy structural interference. For infrastructure inspection, long-range survey, or public safety work in built-up areas, that's the difference between a reliable link and one that drops out mid-mission.

Does this work with the standard RC Plus 2, or only the Enterprise Enhanced?
Built for the RC Plus 2 Enterprise Enhanced specifically. If you're running the standard RC Plus 2, check with our team before ordering, since fitting it to the wrong controller variant won't give the transmission benefit this module is designed for.
Can I use sub-2GHz frequencies anywhere in the UK?
Only with the appropriate authorisation from Ofcom. Permitted frequency bands and power output vary by country, and the figures published for FCC, MIC, and SRRC regions don't automatically apply here. Confirm your specific authorisation before relying on this operationally.
Does this replace the standard O4 transmission link?
No, it adds additional frequency bands alongside the existing link, giving better penetration in obstructed environments rather than replacing the primary connection.
Does fitting this affect the controller's other functions?
No, it's a rear-mounted, plug-and-play addition that doesn't interfere with the RC Plus 2 Enterprise Enhanced's existing controls or connections.
What warranty comes with it?
As an official DJI retailer, we offer 24 months warranty on this product. Our team can confirm specific coverage before you buy.
Can I get this on finance?
Ltd companies can access iwocaPay financing, and individual buyers can use Klarna or Clearpay at checkout.
Why Buy From Drone Safe Store
Every sub2G SDR Module ships from UK stock. Sub-2GHz operation needs the right regulatory authorisation to be usable at all, so call us before ordering and we'll point you toward what you need to confirm with Ofcom first.
