Receiver range has dropped

The antenna is exposed to weather conditions year-round, so it's a good idea to inspect it periodically to ensure everything is in good condition.

Check the following

Antenna: Look for any cracks, bends, loose parts, or other visible damage.

Coaxial cable: Inspect the entire length of the cable for cuts, kinks, crushed sections, or signs of wear.

Connectors: Make sure all connectors are securely tightened and free from corrosion, rust, dirt, or moisture.

Water ingress: Check for any signs of water inside the connectors or cable. Water can significantly reduce signal quality and may eventually damage the cable or antenna.

Even minor damage or corrosion can increase signal loss and reduce the number of aircraft your receiver is able to detect.

Try repositioning the antenna

If the antenna and cable appear to be in good condition but reception is still poor, try adjusting the antenna's location.

For the best results, the antenna should be:

• Mounted as high as possible.
• Installed vertically.
• Positioned with a clear, unobstructed 360° view of the horizon.
• Kept away from nearby buildings, trees, metal structures, and other objects that may block or reflect radio signals.

Even moving the antenna a short distance or raising it by a meter or two can noticeably improve reception. If possible, test a few different locations and compare the number of aircraft received before deciding on the final installation point.
