With groundbreaking products and technology, ImmersionRC brings you a more immersive FPV experience.


Part Number: IMR-DUO5800V4RE


Product Description



  • The Duo5800 includes ImmersionRC’s NexWaveRF technology, increasing inter-brand compatibility, and providing clean video in even the harshest of RF conditions.
  • Dual, independent receivers greatly increase usable range
  • Frequencies: 5740, 5760, 5780, 5800, 5820, 5840, 5860MHz as standard, with 32 channel mode supporting most competitor's transmitters.
  • Race Band will allow race band channels availble in the Vortex. This band falls within the legal US ham band, and can be sold domestically.
  • A/V receiver with diversity antenna inputs
  • GS-Link (Groundstation Link) for direct single-cable connection to the ImmersionRC Groundstation (soon to be released)
  • >-90dBm typical sensitivity (using NexWaveRF module technology)
  • SMA female antenna connectors, compatible with standard 5.8GHz antennas (omni or directional)
  • Compatible with 'DC Short' antennas (such as the Cloverleaf, and SPW)
  • Audible Low-battery alarm, Duo5800v4 uses a switching regulator for lower power consumption, and runs much cooler
  • Inputs filtered against nearby 2.4GHz and UHF R/C radios.
  • Input voltage 6-16V DC (2.1mm plug, center pin positive)
  • Triple A/V output, for three viewing/recording devices
  • Single-button user interface, and remote control from the groundstation
  • ~1km range with 25mW CE-Legal transmitters

Diversity may be used in several ways, all of which provide a better FPV experience.

  • Use two patch antennas to cover a wider flight area.
  • Use a patch, and an omni directional antenna to provide 360 degree coverage for landing approaches
  • Use antennas with opposite circular polarization to ensure that stronger CP reflections are used

32 Channel Support

  • Version 4 of the Duo5800 introduces 32 channel support. Four bands are fully supported, including the standard ‘Airwave’ band used for all ImmersionRC and FatShark 5.8GHz transmitters to date.
  • All other common 5.8GHz FPV frequencies are also fully supported, including Boscam, Team Black Sheep, DJI, etc.

Filtered Inputs

  • To eliminate the range-reducing effects of co-located UHF, or 2.4GHz uplinks, the Duo5800 is equipped with two high-performance RF filters, one on each of it’s independent receiver inputs.

The Smart Receiver

  • The Duo5800 is the first in a line of ‘smart’ receivers, designed for single-cable, plug and play, integration with the ImmersionRC Antenna Tracker (v2) system (Part#: IMR-EZANTRKV2). Power, Audio, Video, and a bi-directional data link, are all passed through a single Mini-Din connector, connected to the Antenna Tracker.

A Patch Above

  • Directly connect one of the Duo5800’s SMA input to an ImmersionRC 5.8GHz, 13dBi patch antenna (Part#: IMR-SNAN5G8P-L/IMR-SNAN5G8P-R). for a serious range boost. Connect two of them to cover a larger area, with automatic switching between the two.
  • Install the Duo, and it’s antennas on an antenna tracker (Part#: IMR-EZANTRKV2) to follow a model around the sky. The 13dBi patch provides at least a factor of 4 increase in range, even for license-free 25mW Transmitters. (Part#: IMR-TX5G8-25).
