Broadcast transmitters offer convenient viewing on standard television sets and portable tuners, but may pose legal risks including equipment confiscation if discovered
Microwave systems provide legal operation without regulatory concerns but require purchasing multiple receivers which increases costs
UHF transmission generally produces better image quality with gradual degradation during interference rather than sync loss and flickering, and penetrates through walls and obstacles more effectively
Microwave systems can suffer from white horizontal line artifacts caused by interference from follow focus devices or wireless phones operating on overlapping frequencies
1.2 GHz systems operate in less crowded spectrum than UHF and can achieve line-of-sight ranges around three-quarters of a mile with appropriate antennas
Portable TV tuners cannot receive microwave signals, but microwave receiver units can output video to broadcast transmitters for flexibility
Microwave systems configured with integrated monitors eliminate cables between camera and director while maintaining picture quality

Discussion from 2006, equipment models and regulations may have changed
Claims about FCC legality depend on duty cycle and are not definitively established in the thread
Specific interference problems vary by location and frequency band availability
Personal preference stated regarding audio transmission capability is anecdotal
Some opinions about system superiority are based on individual experience rather than controlled testing
Pricing and availability of discussed prototypes uncertain at time of posting
