Features: Exceptional sensitivity and accuracy to help you find the optimal position for your DVB-T antenna. Integrated compass for quick and easy alignment. User-friendly operation with audible tone and damping control. Intuitive feedback numbers indicate signal strength. Compact and lightweight design for ultimate portability. How to Use: 1. Connect the antenna cable to the left F female port and the battery cable to the right F female port. Remove any external amplifiers connected to the antenna. 2. Adjust the antenna to the best position by observing the meter reading. A higher reading indicates a stronger signal. If the meter reaches full scale, adjust the level control knob to reduce the reading to approximately 5 (turning the knob clockwise decreases the reading). Continue moving the antenna until you achieve the highest possible meter reading. 3. Remove the finder and reconnect any disconnected amplifiers. Important Note: If your antenna has an internal amplifier (e.g., 01MM-SQ01), it must be powered by an external power supply via a DC power injector. Ensure the power injector is placed between the finder and the antenna.
