DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.

A transmitter's effective range is limited, typically around 50 feet under favorable conditions.
Selecting a transmitter channel that produces the clearest picture on a receiver is a practical approach.
Store security systems can interfere with wireless video transmitter performance.
Power cycling and antenna connection procedures, while recommended, do not critically determine transmitter reliability in practice.
After digital television transition, certain UHF channels were repurposed for other uses rather than remaining available for wireless video devices.
Analogue television receiver manufacturing and importation became prohibited in some regions once digital television standards were established.
Legal wireless video options operate on 2.4 GHz frequency band, though this band experiences congestion from other wireless technologies.
Higher frequency bands like 1.2 GHz are reserved for critical aviation safety systems and represent inappropriate choices for video transmission.
UHF television channel numbering differs between equipment labeling and broadcast standards in different regions.

Discussion predates modern wireless video standards and regulations.
Legal status and enforcement varies significantly between countries and regions.
Experiences described are from the United States and United Kingdom specifically.
Some claims about enforcement actions and equipment confiscation are anecdotal.
Information about FCC procedures and authority is based on incomplete recollection by participants.
Digital television transition timeline and specific frequency reassignments varied by region.
The practical range and interference characteristics are device and environment-dependent.
