3. Product Overview
The Televes 404401 is a high-rejection (HR) filter specifically engineered to block unwanted signals from the 800 MHz LTE/4G band, which can cause pixelation, signal loss, or other reception issues on television channels. It operates within the 47-782 MHz frequency range, covering TV channels up to C59, and uses a standard CEI connector for easy integration into existing antenna systems.

4. Setup
Follow these steps to install the Televes 404401 LTE HR Filter:
- Identify the Connection Point: The filter should be installed in the coaxial cable path between your antenna and your television or set-top box. For optimal performance, install it as close to the antenna as possible, before any signal amplifiers or splitters.
- Disconnect Power: Before making any connections, ensure that your television and any associated signal amplifiers are powered off and unplugged from the mains electricity supply.
- Connect the Antenna Cable: Take the coaxial cable coming from your antenna and connect it to one end of the Televes 404401 filter. Ensure the CEI connector is firmly screwed or pushed into place.
- Connect to TV/Set-top Box: Take a new coaxial cable (or the existing one if it reaches) and connect one end to the other side of the Televes 404401 filter. Connect the other end of this cable to the antenna input of your television or set-top box.
- Secure Connections: Verify that both connections to the filter are tight and secure to prevent signal leakage or degradation.
- Restore Power: Plug in and power on your television and any other connected equipment.
- Rescan Channels: Perform a channel rescan on your television or set-top box to allow it to detect available channels with the new filter in place. This may be necessary to fully benefit from the improved signal quality.
5. Operating Instructions
The Televes 404401 LTE HR Filter is a passive device and does not require any active operation once installed. It functions automatically to filter out unwanted LTE/4G signals from your antenna feed. Once properly installed, you should experience improved television reception, particularly if you were previously affected by mobile broadband interference.
6. Maintenance
- Cleaning: The filter requires minimal maintenance. If necessary, gently wipe the exterior with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Inspection: Periodically check the coaxial cable connections to ensure they remain secure and free from corrosion.
- Environmental Conditions: Ensure the filter is not exposed to harsh weather conditions if installed outdoors, unless housed in a suitable weatherproof enclosure.
7. Troubleshooting
- Still experiencing interference:
- Verify all coaxial connections are tight and correctly installed.
- Ensure the filter is placed correctly in the signal path (ideally before any amplifiers).
- Confirm that the interference is indeed from LTE/4G signals. Other sources of interference may require different solutions.
- Try rescanning channels on your TV or set-top box.
- No signal or worse signal after installation:
- Check all cable connections for looseness or incorrect wiring.
- Ensure the filter itself is not faulty by temporarily bypassing it to see if the signal returns.
- Confirm that the filter is compatible with your specific TV channels (this filter supports up to C59).
- If problems persist, consult a professional antenna installer or contact Televes customer support.
