If you’re looking for a reliable way to protect your receiver from surges while ensuring stable and secure signal transmission, the new QRO.cz protection box for under 70 € is the perfect solution. This product connects your antenna to the receiver while providing several key safety features to keep your system safe and efficient.

Automatic Disconnection Without Power: When power is not applied, the antenna is disconnected from the output, and the unit includes surge arrestors on the coaxial cable and between the coax shielding and the ground screw. RF Signal Limiting for Strong Signals: When power is supplied, the relay contacts connect the input RF signal to the output through an RF limiter, which safely limits any strong signals to a safe value. Overcurrent Protection: An integrated SuperFuse disconnects the signal path if the current exceeds 100mA, protecting the limiter from damage. Easy Grounding Setup: For proper operation, the box needs to be grounded via the provided ground screw to a good earth connection.
