The Televes DAT BOSS LR antenna incorporates advanced technology to enhance signal reception, particularly in challenging environments or for long-distance signal acquisition. Its design focuses on maximizing gain and minimizing interference, including LTE700 filtering.
2. Safety Information
Always observe the following safety precautions during installation and operation:
- Professional Installation Recommended: Antenna installation, especially on rooftops or tall structures, can be hazardous. It is highly recommended to seek assistance from a qualified professional installer.
- Avoid Power Lines: Never install the antenna near overhead power lines or other electrical circuits. Contact with power lines can be fatal.
- Stable Mounting: Ensure the antenna is securely mounted to a stable structure that can withstand wind and other environmental factors.
- Grounding: Properly ground the antenna mast and lead-in wire according to local electrical codes to protect against lightning strikes.
- Weather Conditions: Do not attempt installation during adverse weather conditions such as strong winds, rain, or lightning.
- Use Appropriate Tools: Use only insulated tools and wear appropriate safety gear, including gloves and eye protection.
3. Package Contents
Verify that all components are present before beginning installation:
- Televes 149721 DAT BOSS LR UHF Antenna (main unit)
- Mounting hardware (mast clamp, bolts, nuts, washers)
- Instruction Manual (this document)
- Note: Coaxial cable and mast are typically sold separately.
4. Assembly
The Televes DAT BOSS LR antenna is designed for straightforward assembly. Follow these steps:
- Unpack Components: Carefully remove all parts from the packaging.
- Extend Elements: The antenna elements may be folded for shipping. Gently extend and lock them into their operational positions. Refer to the diagrams for correct orientation.
- Attach Reflector (if separate): If the reflector grid is separate, attach it to the main boom using the provided hardware. Ensure it is securely fastened.
- Mounting Clamp Assembly: Assemble the mast clamp onto the antenna's mounting point. Do not fully tighten yet, as adjustments may be needed during installation.

5. Setup and Installation
Proper installation is crucial for optimal performance. Consider the following:
- Location Selection: Choose a mounting location that provides a clear line of sight to the broadcast towers. Higher elevations are generally better. Avoid obstructions like buildings, trees, or hills.
- Mounting the Antenna:
- Securely attach the antenna to a sturdy mast using the provided mounting hardware.
- Ensure the antenna is level and oriented correctly.
- Tighten all bolts firmly to prevent movement in windy conditions.
- Coaxial Cable Connection:
- Connect a high-quality 75-ohm coaxial cable (RG6 recommended) to the antenna's F-connector.
- Ensure the connection is tight and weatherproof. Use weatherproof tape or a rubber boot if not already integrated.
- Route the cable carefully, avoiding sharp bends and securing it to the mast and structure to prevent damage.
- Connecting to TV/Receiver:
- Connect the other end of the coaxial cable to the "Antenna In" or "RF In" port on your television or digital TV receiver/tuner.
- If using a signal amplifier or distribution amplifier, connect the antenna to the input of the amplifier, and the amplifier output to your TV(s).
- Antenna Aiming:
- Use an online tool or a compass to determine the direction of your local broadcast towers.
- Aim the front (narrow end) of the antenna directly towards the primary broadcast towers.
- Fine-tune the direction while monitoring signal strength on your TV or a signal meter for optimal reception.

6. Operating the Antenna (Tuning)
Once the antenna is installed and connected, perform a channel scan on your television or digital TV receiver:
- Access TV Menu: Navigate to your TV's or receiver's menu.
- Select "Antenna" or "Air" Input: Ensure your TV is set to the correct input source.
- Initiate Channel Scan: Look for options like "Channel Scan," "Auto Program," or "Auto Tune" in the setup or channel settings menu.
- Monitor Results: The TV will scan for available channels. This process may take several minutes.
- Fine-Tuning (if necessary): If certain channels are missing or have poor reception, try slightly adjusting the antenna's direction and re-running the channel scan.
The DAT BOSS LR antenna features a built-in BOSS Tech system (Balanced Output Signal System) which automatically adjusts the output level to optimize reception. This intelligent system helps prevent signal overload and ensures a stable signal quality.
7. Maintenance
The Televes DAT BOSS LR antenna is designed for durability and requires minimal maintenance. However, periodic checks can ensure long-term performance:
- Visual Inspection: Annually inspect the antenna, mast, and mounting hardware for any signs of corrosion, damage, or loosening.
- Cable Integrity: Check the coaxial cable for cracks, fraying, or damage to the outer jacket. Ensure all connections remain tight and weatherproof.
- Debris Removal: Remove any accumulated leaves, branches, or other debris that might obstruct the antenna elements.
- Cleaning: If necessary, gently clean the antenna with a soft cloth and mild detergent. Avoid abrasive cleaners or high-pressure water.
Warning: Always exercise extreme caution when working at heights. If you are uncomfortable or unqualified, hire a professional for maintenance.
