1. Introduction and Product Overview
The Goobay 67510 LTE/4G Blocking Filter is designed to enhance DVB-T (Digital Video Broadcasting – Terrestrial) reception by filtering out unwanted interference from LTE (4G) mobile signals. This filter ensures a clearer and more stable television signal, particularly in areas where LTE/4G transmissions may overlap with DVB-T frequencies. It is a passive device, requiring no external power, and is built for durability in outdoor environments.

2. Setup and Installation
Follow these steps to correctly install your Goobay 67510 LTE/4G Blocking Filter:
- Identify Connection Points: Locate the coaxial cable connecting your DVB-T antenna to your television or DVB-T receiver.
- Disconnect Cable: Carefully disconnect the coaxial cable from your DVB-T receiver or the point where you intend to insert the filter.
- Connect Filter: The filter has two F-female connectors, labeled 'IN' and 'OUT'. Connect the coaxial cable coming from your antenna to the 'IN' port of the filter.
- Connect to Receiver: Connect a new coaxial cable (or the existing one if it reaches) from the 'OUT' port of the filter to your DVB-T receiver or television's antenna input.
- Secure Connections: Ensure all F-connectors are securely tightened to prevent signal loss and maintain the waterproof integrity of the filter, especially if installed outdoors.
- Positioning: For optimal performance, install the filter as close as possible to the antenna. The filter is designed for outdoor use and is waterproof.
Note: This filter is designed to block specific frequency ranges. Ensure your DVB-T signals are within the filter's pass-through range (5 MHz to 790 MHz) and that LTE/4G interference is within its blocking range (790 MHz to 2050 MHz).
3. Operating Instructions
The Goobay 67510 LTE/4G Blocking Filter is a passive component and does not require any active operation once installed. It continuously filters out unwanted LTE/4G signals from your DVB-T antenna feed. After installation, you may need to perform a channel scan on your DVB-T receiver or television to detect improved signal quality and available channels.
4. Maintenance
The Goobay 67510 LTE/4G Blocking Filter requires minimal maintenance due to its robust and waterproof design. To ensure continued optimal performance:
- Periodically inspect all coaxial cable connections to ensure they remain tight and free from corrosion.
- Check the filter and cables for any visible physical damage, especially if installed outdoors.
- Clean the exterior of the filter with a soft, damp cloth if it becomes dirty. Do not use harsh chemicals or abrasive materials.
5. Troubleshooting
If you experience issues after installing the LTE/4G blocking filter, consider the following troubleshooting steps:
- No Signal or Poor Reception:
- Verify that all coaxial cable connections are secure and correctly attached to the 'IN' and 'OUT' ports of the filter.
- Ensure the antenna is properly aimed and free from obstructions.
- Perform a new channel scan on your DVB-T receiver or television.
- Temporarily bypass the filter to determine if the issue is with the filter itself or other components of your antenna system.
- Signal Still Affected by Interference:
- Confirm that the interference you are experiencing is indeed from LTE/4G signals operating within the filter's blocking band (790 MHz to 2050 MHz). Other types of interference may not be resolved by this filter.
- Ensure the filter is installed as close to the antenna as possible to minimize the length of cable susceptible to interference before filtering.
Important: This device is a filter, not an amplifier. It will not boost a weak signal. Its purpose is to remove specific interference to clarify an existing signal.
