## Long description

EMOS J0400 (EM440) is a broadband amplifier engineered to increase signal strength across a wide frequency range for TV, FM and antenna distribution systems. Designed for domestic and small commercial installations, this unit compensates for cable losses and supports improved reception quality for multiple receivers connected through a single distribution network. The compact design and general-purpose performance make it suitable where a reliable, wideband signal boost is required.
Advantages
The amplifier provides uniform gain across a broad spectrum, reducing signal degradation from long cable runs and passive splitters. Its straightforward installation and compatibility with common coaxial antenna systems allow for quick integration into existing setups. The device helps stabilize reception quality for analogue and digital TV as well as FM radio, and it operates without complex configuration, delivering consistent amplification for multiple outlets.
Suitable for
Home antenna systems to improve TV and FM reception
Small commercial premises with simple distribution networks
Installations requiring compensation for cable attenuation or splitter loss
Multiroom setups with several receivers sharing one antenna
Key specifications
Broadband frequency coverage suitable for TV and FM signals
General-purpose gain to compensate for cable and splitter losses
Compact form factor for easy mounting in distribution boxes or near antenna feeds
Passive external power requirement or internal power supply option depending on installation (verify existing setup compatibility)
Coaxial input and output connectors compatible with standard antenna cables
How to use
Connect the antenna feed to the amplifier input and attach the amplifier output to the distribution line or directly to the receiver. If the unit requires external power, connect it to a suitable power source following manufacturer instructions and ensure correct polarity and voltage. Position the amplifier near the antenna or at the start of the distribution network to maximize compensation for cable losses. After connection, verify signal levels on each receiver and adjust placement if necessary to avoid overloading sensitive tuners.
Usage recommendations
Use the amplifier to correct signal loss over long coaxial runs and where multiple splits reduce level. Avoid placing the amplifier downstream of excessive noise sources and ensure grounding and shielding of coaxial connections to maintain signal quality.
