HIGH GAIN CATV AMPLIFIER Product Model: HGA-862-40

ASTEL High Gain amplifier is primarily used for long branch or distribution lines where higher gain is required.

Astel HGA-862-40 uses an extra push pull Pre-amplification stage to increase the gain and keep the noise low.

Main Features

1. ASTEL HGA-862-40 model features low Noise Cable TV Hybrid Module design, signal level
adjustments, and thus is thus widely used in Cable TV branch or distribution lines. In a typical
situation , a few extra dB of gain would drive the distribution line by 30-40 meters of branch or
serve and extra customer.

2. Built in Surge arrestors and thus protects your expensive equipment from very high lightning
inrush current.

3. Built in ATC (Auto Temperature Compensation circuit) to minimize the changes in amplification
factor due to temperature changes.

4. High Price Performance Ratio.
5. Aluminum Alloy housing, waterproof, and dust proof and anti Electromagnetic interference resistant.
6. Built in Surge protectors.
7. Metal housing helps in faster heat dissipation.
8. Hybrid Module Design.
9. Adjustable Gain and Slope.
10. Output mode 1 way with coupler (test) or 2 way splitter.
