Product Information

• LOG28T – 28 Element Log Periodic Aerial
  • The LOG28T is a log periodic aerial designed for the reception of all available signals in strong and medium areas. It is LTE800 ready, ensuring compatibility with the latest technology.
• Installation Instructions
  • To achieve optimum results, follow these installation instructions:
• Prepare the Coax Cable
  • Fit the rubber weather boot provided to the aerial end of the cable.
  • Strip the end of the cable, as shown in Fig. 1.
  • Twist the braid and pull it back on itself, ensuring no braid touches the copper core to avoid signal loss.
  • Refer to Fig. 1 and Fig. 2 for visual guidance.
• Fitting the F Connector
  • Twist on the F connector supplied and trim the central conductor.
  • Screw the connector body onto the cable, ensuring the end of the insulation is flush with the face of the connector.
  • Refer to Fig. 2 for visual guidance.
• Mounting the Aerial
  • For best results, mount the aerial on an outdoor aerial mast, pointed towards the nearest transmitter.
  • Ensure there are no obstructions such as trees or buildings blocking the transmitter signal.
  • If unsure about the direction or orientation of the aerial, check your neighbors’ aerials.
  • If mounting on an existing mast, ensure it is in good condition and firmly fixed.
  • Use the mast clamp supplied to hold the aerial firmly in a horizontal position, as shown in Fig. 3.
  • Refer to Fig. 3 for visual guidance.
• Connect the Aerial Download
  • Connect the aerial download to the F socket on the back of the aerial. Be careful not to over-tighten the F connector. Refer to Fig. 5 for visual guidance.
• Secure the Connections
  • Slide the weather boot over the F connector and socket to create a good seal.
  • Tape the coax cable to the mast using insulating tape to ensure a secure connection.
  • Refer to Fig. 6 for visual guidance.
• Finalize the Installation
  • Connect the aerial to your TV or other reception device and check the picture. Fine-tune the direction of the aerial for optimum signal reception.
• Troubleshooting
  • If you encounter any issues, refer to the following troubleshooting steps:
• No Picture
  • Check all connections from aerial to TV.
• Poor Picture
  • Check all connections from aerial to TV.
  • Check that the aerial is properly aligned to the correct transmitter.
  • If the aerial has been loft-mounted, try mounting it outside.
• Signal Improvement
  • Make sure the new digital coax cable has been used throughout the installation.
  • Check that the transmitter signal is not obstructed by nearby trees or buildings.
  • In weak signal areas or for long cable runs, consider installing a masthead amplifier to improve signal strength.
  • In strong signal areas, fitting an attenuator may be necessary to reduce signal strength.

INTRODUCTION

Congratulations on the purchase of your log periodic aerial. The aerial is ideal for the reception of all available signals in strong and medium areas.

• The built-in filter removes any signals from Lte 800 4G mobile phone transmitters
• F type connection
• Superior rejection of impulse noise – the largest cause of picture freezing and signal dropout on Freeview reception
• Gain 10.2dBi
• Highly directional
• Very low wind resistance
• Supplied fully assembled with mast clamp, F connector, and rubber weather boot

Installation Instructions

For optimum results install the aerial using double screened CAI approved digital coax cable and screened coax outlets. You will need to fit the coax cable with the F-type connector supplied to connect the download (not supplied) to the F socket on the aerial.

1. Prepare the Coax Cable: Firstly fit the rubber weather boot provided, to the aerial end of the cable. Strip the end of the cable as shown in Fig. 1. Once you have stripped the cable, twist the braid and pull it back on itself, make sure that no braid is touching the copper core, this will cause a short on the cable and you will not get any signal.
2. Fitting the F connector: Now, simply twist on the ‘F’ connector supplied and trim the central conductor.
   • For best results, the aerial should be mounted on an outdoor aerial mast and pointed in the direction of the nearest transmitter* making sure it is in a position where the transmitter signal will not be obstructed by nearby trees and buildings. If you are in any doubt about the direction in which the aerial should be pointing or the orientation of the aerial (horizontal for the main transmitter, vertical for the relay transmitter) check your neighbors’ aerials. The aerial comes fully assembled. If mounting on an existing mast check that the mast is in good condition and firmly fixed.
3. Use the mast clamp supplied and tighten the wing nuts tightly until the aerial is held firmly in a horizontal position as shown in Fig. 3.
4. Connect the aerial download to the ‘F’ socket on the back of the aerial (be careful not to over-tighten the F connector) see Fig. 5.
5. Slide the weather boot over the ‘F’ connector and socket to make a good seal – see Fig. 6. Make sure that the coax cable is taped to the mast. Use insulating tape, to secure the coax download to the mast.
6. Finally, connect the aerial to your TV or other reception device and check the picture. Fine, adjust the direction of the aerial to obtain the optimum signal reception.

Troubleshooting

• No picture:
  • Check all connections from aerial to TV.
• Poor picture:
  • Check all connections from aerial to TV.
  • Check aerial is properly aligned with the correct transmitter.
  • If the aerial has been loft mounted try mounting outside.
  • Make sure the new digital coax cable has been used throughout the installation.
  • Check the transmitter signal is not obstructed by nearby trees or buildings.
  • If in a very weak signal area or for long cable runs, installing a masthead amplifier will improve the signal.
  • If in a strong signal area, the signal strength may need to be reduced by fitting an attenuator.
