Setup and Installation

The DX Antenna UHF Dual Booster BU433D1 is designed for outdoor installation, typically on a horizontal mast near your UHF antenna.

  1. Mounting the Booster: Securely attach the booster unit to a horizontal mast using the provided mounting hardware. Ensure it is positioned to minimize cable length from the antenna.
  2. Connecting the Antenna: Connect the UHF antenna's coaxial cable to the input port of the booster. Use an F-type connector and ensure a tight, secure connection.
  3. Connecting to TV/Distribution System: Connect a coaxial cable from the output port of the booster to your TV or distribution amplifier. Again, use an F-type connector and ensure a secure connection.
  4. Power Connection: Connect the power supply unit (sold separately or integrated) to the booster. Ensure the power supply is rated correctly for the booster.
  5. Weather Protection: Use the provided weather boots over the F-type connections to protect them from moisture and environmental elements.

Operating Instructions

Once installed, the booster operates automatically. However, you may need to adjust the gain settings for optimal signal reception.

  1. Power On: Connect the booster's power supply to an electrical outlet. The booster will power on.
  2. Gain Adjustment: The booster features a gain adjustment range of 0 to -10 dB (continuous variable) and a gain switch with settings for 28, 33, and 43 dB.
    • Start with a lower gain setting and gradually increase it until you achieve clear picture quality on your television.
    • Avoid setting the gain too high, as this can lead to signal over-amplification and distortion.
    • Refer to your TV's signal strength meter (if available) for precise adjustment.
  3. Channel Scan: After adjusting the gain, perform a channel scan on your television to detect all available channels with the boosted signal.

Maintenance

The DX Antenna UHF Dual Booster BU433D1 requires minimal maintenance.

  • Regular Inspection: Periodically check all cable connections for tightness and ensure weather boots are properly seated to prevent moisture ingress.
  • Cleaning: If necessary, gently wipe the exterior of the unit with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
  • Environmental Protection: Ensure the unit remains free from obstructions that could impede ventilation.

Troubleshooting

If you experience issues with your booster, refer to the following common problems and solutions.

ProblemPossible CauseSolution
No signal or poor picture quality
  • Loose cable connections
  • Incorrect gain setting
  • Power supply issue
  • Antenna not properly aimed
  • Signal over-amplification
  • Check and tighten all F-type connections.
  • Adjust the gain setting (try lower settings if signal is too strong, higher if too weak).
  • Ensure the power supply is connected and functioning.
  • Verify antenna direction and clear line of sight to broadcast towers.
  • Reduce gain to prevent distortion.
Intermittent signal loss
  • Weather-related interference
  • Loose connections
  • Damaged cable
  • Ensure weather boots are properly installed.
  • Check and tighten all connections.
  • Inspect coaxial cables for damage and replace if necessary.
Booster not powering on
  • Power supply not connected
  • Faulty power outlet
  • Damaged power supply
  • Verify power supply is securely plugged into both the booster and a working electrical outlet.
  • Test the outlet with another device.
  • Replace the power supply if it is suspected to be faulty.

If problems persist after attempting these solutions, please contact customer support.
