Modulos wireless video transmitter causing monitor blackouts on video assist

DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- The Modulos transmitter can cause HD-SDI video signals to black out due to radio frequency interference when placed too close to video cables or monitors.
- Wrapping the Modulos antenna with conductive material or shielding can reduce the interference and restore the video signal.
- The interference problem is more pronounced with certain camera setups and may require repositioning the transmitter away from video connections.
- RF interference from wireless transmission can also occur with other transmitting devices placed near HD monitors.
- Insufficient shielding in video cables allows the transmitter's RF output to interfere with the incoming video signal.
Depends on
- The solution using wrapped antenna shielding worked initially but stopped working reliably after several days.
- The interference varies depending on which camera is being used for the video source.
- The root cause remains partially unresolved as the symptom recurred despite initial successful mitigation.
- No definitive permanent solution was established in the thread.
