Lo que encontró el hilo

• Un prototipo de transmisor de vídeo de 1.2 GHz usando un conector Hirosche puede funcionar continuamente durante al menos tres semanas con una gama de aproximadamente tres cuartos de milla en condiciones de línea de visión utilizando una antena de látigo en el transmisor y yagi en el receptor.
• El sistema acepta la entrada DC de 9-36 voltios, características de entrada de vídeo BNC, múltiples canales seleccionables a través del interruptor de diapositivas, y salida del receptor en XLR 4-pin con compatibilidad de 9-36 voltios.
• La banda de frecuencia 1.2 GHz ofrece menos congestión que UHF para transmisión de vídeo inalámbrica.
• Picture quality improves when audio is not mixed with video transmission.
• Reception quality and receiver design are often more critical to performance than transmitter output power for typical film production ranges.
• Non-line-of-sight signal penetration was observed at short range through building structures including elevator shafts and exterior walls.
• Regulatory compliance in the United States may differ significantly from European regulations regarding transmitter output power levels.

Depende de

• Initial prototype specifications were from 2006 and may not reflect current designs.
• European legal restrictions on output power in this frequency range conflict with US allowances; this system was specifically not intended for export.
• Field testing was conducted with a pinhole camera and portable LCD monitor rather than professional cinema cameras.
• No comprehensive long-range line-of-sight range testing results with yagi antennas were provided.
• Disagreement exists between contributors regarding regulatory legality of high-power 1.2 GHz transmitters outside the United States.
