Antenna Signal Amplifier Telmor WSS-218R 2x-18 dB with Return Channel

Telmor WSS-218R is an antenna signal amplifier designed for terrestrial TV and FM reception systems. It provides two bands of gain rated at 2x-18 dB and includes a return channel, enabling improved upstream communication for distribution systems. The amplifier is intended to boost weak signals, reduce noise, and support longer cable runs, making it suitable for home installations and small communal setups that require signal equalization and distribution across multiple receivers.

Advantages

The device delivers dual-band amplification with consistent gain across its two bands, improving both picture and sound quality for terrestrial television and FM radio reception. The included return channel allows signals to be sent back through the same coaxial infrastructure, facilitating interactive services or remote equipment control. Compact design and robust construction allow mounting near the antenna or in a distribution point to minimize signal loss on cable runs.

Suitable for

• Private homes requiring improved terrestrial TV reception and FM radio quality
• Small apartment buildings and communal antenna systems with multiple receivers
• Installations that need signal equalization across long cable runs
• Systems that require a return channel for interactive or upstream signals

Key specifications

• Dual-band gain: two amplification bands with up to 18 dB gain each
• Return channel: integrated return path for upstream signals
• Application: terrestrial television and FM radio reception systems
• Installation: suitable for mounting near antenna or in distribution points to reduce cable attenuation
• Function: signal boosting, noise reduction, and support for longer cable lengths

How to use

Install the amplifier as close to the antenna as practical to minimize cable loss between the antenna and amplifier input. Connect the antenna coax to the amplifier input and route output(s) to the distribution network or directly to receivers. If using the return channel, connect the upstream service or equipment according to the system design, ensuring correct polarity and impedance matching for coaxial lines. Power the amplifier following the manufacturer’s instructions and verify signal levels on connected receivers, adjusting attenuation or gain settings if available to achieve even distribution across outlets.

Usage recommendations

For optimal performance, use quality coaxial cable and connectors, keep cable runs as short as possible between the antenna and amplifier, and avoid unnecessary splitters before amplification. Perform signal level measurements at receiver outlets after installation to verify balanced distribution and to prevent overamplification that can cause distortion.
