Essential Race Day Connections

Antenna Connections

Receive Loop Sockets

Connect the receive cable(s) from your antennas.

Transmit Loop Sockets

Cable Management Tips

Before the Race

  1. Connect all cables securely

  2. Route cables to avoid tripping hazards

  3. Use cable ties to bundle excess length

  4. Test all connections with test tag

During the Race

  1. Periodically check connections are still secure

  2. Watch for cables being pulled or disturbed

  3. Protect cable connection points from weather

Troubleshooting Connections

If you suspect a connection issue:

  1. Disconnect and reconnect the suspect cable

  2. Check both ends of the cable

  3. Look for visible damage to cables or connectors

  4. Try a different port if available (e.g., alternate ethernet port)
