Stable PLL SCART to RF Modulator for Analog TVs

This SCART-to-RF modulator transforms SCART-sourced composite video and stereo audio into a single, high-gain RF signal compatible with standard analog TV tuners. Physical size: ~8.5 × 5.5 × 2.5 cm; net weight: 95 g. Delivers two selectable fixed RF output frequencies (61.25 MHz and 67.25 MHz), with full customisation available across 40–900 MHz range. RF output gain: 80 dB. Default video/sound system: PAL DK; optional configurations include I/BG, M/N/L, SECAM and NTSC — tailored to national broadcast standards. Powered via 5 V / 500 mA USB input; total power draw under 0.5 W. Engineered with an imported PLL-stabilised RF modulation chip, it guarantees constant carrier frequency accuracy — preventing the pitch-shifted audio or rolling picture often seen with low-cost non-PLL RF adapters. Signal integrity remains high even over extended coaxial runs, effectively extending usable connection distance from ≤2 m (native SCART) to ≥100 m — practical for distributed home entertainment or commercial signage applications. Includes one SCART-to-RF converter unit, one standard 75 Ω RF coaxial cable (male-male), and one micro-USB power cable. Compatible with all SCART-output devices (DVD players, satellite/cable receivers, gaming consoles, media streamers) and analog TVs featuring RF antenna input — whether vintage CRTs or newer digital-ready sets with analogue fallback mode.
