LLC400 Ultra Low loss 400 Cable is designed to minimize signal loss over long distances. Here are some benefits of using LLC400:

Reduced Signal Loss: Low loss 400 cable has a lower attenuation rate than standard coaxial cables, meaning it can transmit signals over longer distances without losing strength. This makes it ideal for use in applications where long cable runs are necessary, such as in wireless networks, broadcasting, and cellular communication.

The cable loss (also known as attenuation) is a critical factor in determining the performance of coaxial cables, especially in RF applications. The LMR400 and LLC400 cables are designed to minimize signal loss, but there can be differences in their specifications. Here’s a comparison focusing on the cable loss differences:

Times Microwave LMR400

• Frequency (MHz): Cable loss is typically specified per 100 feet (30.48 meters) for different frequencies.
• 50 MHz: 0.65 dB
• 150 MHz: 1.2 dB
• 450 MHz: 2.0 dB
• 900 MHz: 2.7 dB
• 1500 MHz: 3.4 dB
• 1800 MHz: 3.9 dB
• 2000 MHz: 4.1 dB
• 2400 MHz: 4.5 dB
• 5800 MHz: 7.4 dB

LLC400

• Frequency (MHz): Cable loss per 100 feet (30.48 meters).
• 50 MHz: 0.65 dB
• 150 MHz: 1.2 dB
• 450 MHz: 1.9 dB
• 900 MHz: 2.5 dB
• 1500 MHz: 3.2 dB
• 1800 MHz: 3.6 dB
• 2000 MHz: 3.9 dB
• 2400 MHz: 4.3 dB
• 5800 MHz: 7.2 dB

Summary of Differences

1. Cable Loss at Lower Frequencies (50 MHz, 150 MHz):

   • LMR400: 0.65 dB (50 MHz), 1.2 dB (150 MHz)
   • LLC400: 0.65 dB (50 MHz), 1.2 dB (150 MHz)
   • Difference: Minimal to none.

2. Cable Loss at Mid Frequencies (450 MHz, 900 MHz):

   • LMR400: 2.0 dB (450 MHz), 2.7 dB (900 MHz)
   • LLC400: 1.9 dB (450 MHz), 2.5 dB (900 MHz)
   • Difference: LLC400 slightly lower loss by 0.1 to 0.2 dB.

3. Cable Loss at Higher Frequencies (1500 MHz, 1800 MHz, 2000 MHz, 2400 MHz, 5800 MHz):

   • LMR400: 3.4 dB (1500 MHz), 3.9 dB (1800 MHz), 4.1 dB (2000 MHz), 4.5 dB (2400 MHz), 7.4 dB (5800 MHz)
   • LLC400: 3.2 dB (1500 MHz), 3.6 dB (1800 MHz), 3.9 dB (2000 MHz), 4.3 dB (2400 MHz), 7.2 dB (5800 MHz)
   • Difference: LLC400 slightly lower loss by 0.1 to 0.3 dB.

Conclusion

While both LMR400 and LLC400 cables are designed to minimize signal loss, LLC400 generally exhibits slightly lower attenuation than LMR400 across various frequencies. The differences are small but could be significant in applications requiring the utmost precision and performance.
