Diversity Demon is a video controller that is used
to bridge three wireless video receivers together.
Multiple receivers are used to enhance signal
quality. It is optimized for RF demanding
applications such as FPV drone racing.
FEATURE SUMMARY
Uses your existing wireless composite
video system (NTSC or PAL compatible).
Supports 2-receiver and 3-receiver diversity configurations.
Two audio channels for Mono or Stereo applications.
Very high video bandwidth, superb A/V signal quality. No Latency.
Two front panel mounted A/V outputs, fully buffered.
Compact Size, 5.9 x 4.3 x 1.5 inches.
Operates on 6VDC (2S LiPo) to 25VDC (5S LiPo), 50mA typical.
WHAT IS IT?
Diversity Demon is an intelligent video switch with three A/V (audio/video) inputs that are
multiplexed into a single output. It uses sophisticated realtime video processing technology that
monitors the video signals from three user supplied wireless A/V receivers. If the image begins
to degrade it is switched to a higher quality video source. The video detection is designed for
seamless switching transitions.
Diversity Demon can be used to create a spatial diversity antenna system. This configuration
involves placing the antennas (from two or three receivers) at slightly different locations. As little
as a few inches apart is enough to offer some signal improvement. Spatial diversity can be used
to reduce multipathing interference.
It is also possible to install vastly different antennas on the three video receivers to enhance the
overall antenna performance. For example, you can combine a low gain omni with a medium
gain patch antenna and a high gain directional antenna. This configuration would act as a
hybrid antenna system that automatically switches from short to long range. Or maybe you want
to expand the effective beamwidth of your antenna system? If so, then use three similar
receivers/antennas to triple the RF beamwidth.
The antenna strategy you choose will depend on your operating environment and application
requirements. Although Diversity Demon cannot eliminate all video problems, using it with a
carefully chosen receiver/antenna setup will help reduce reception issues.
