LH-8630RB
XTLineHybrid, 860MHz, Bi-Di, 60V, indoor, switching power supply, return path, aluminium case, Hybrid: BGY-888, Out: 30dB, 18dB, Return Path 5-65MHz
| Installation and operating • Before use the amplifier, test input level whether at the range of input level. You should adjust input level into it. • Output level can’t be too high. Just keep every TV set level at 60~75 dBµV. Turning ATT knob to adjust output level. • When in thunder, to avoid lightning strike, you’d better turn off power supply. The amplifier used indoor only and avoid be affected with damp or high temperature. • Keep power supply voltage at common range. Too low voltage will cause figure quality bad. | ||

Performance characteristics
• Adopt SOT-115 encapsulation RF module on access, reliable non-linear. Choose low-noise micro-wave push-Pull circuit, small distortion and high S/N ratio.
• Set up EQ and ATT on the right place, more convenient of debugging
• Small power consumption, high reliability, good performance and price ratio.
