RT97L Power Output Test Data with Different Feedlines

We conducted power output tests on the 25W RT97L Repeater device paired with various feedlines under two power supply conditions: 15V power adapter and 13.8V car charger. Below are the detailed test results:

1. Test Cable (Baseline Reference)

• 15V Power Adapter Supply:

High Power (H): 22 W

• • Low Power (L): 6.47 W

• 13.8V Car Charger Supply:

  • High Power (H): 19.9 W

• • Low Power (L): 6.47 W

2. Feedline: -12 Caliber, 3m Length

• 15V Power Adapter Supply:

  • High Power (H): 19.9 W

• • Low Power (L): 6.2 W

• 13.8V Car Charger Supply:

  • High Power (H): 18.2 W

• • Low Power (L): 6.44 W

3. Feedline: -9 Caliber, 3m Length

• 15V Power Adapter Supply:

  • High Power (H): 21.3 W

Low Power (L): 6.38 W

• 13.8V Car Charger Supply:

  • High Power (H): 19 W

• • Low Power (L): 6.35 W

4. Feedline: -9 Caliber, 15m Length

• 15V Power Adapter Supply:

  • High Power (H): 13.6 W

• • Low Power (L): 4.1 W

• 13.8V Car Charger Supply:

  • High Power (H): 12.4 W

• • Low Power (L): 4.2 W

5. Feedline: -7 Caliber, 15m Length

• 15V Power Adapter Supply:

  • High Power (H): 15.9 W

• • Low Power (L): 4.9 W

• 13.8V Car Charger Supply:

  • High Power (H): 14.6 W

• • Low Power (L): 4.87 W

Test Conditions:

• The test cable serves as a baseline reference.

• Test data reflects real-world usage scenarios, influenced by feedline type, length, and power supply conditions.

Key Findings:

• Under 15V power adapter supply, high power output approaches 20W with short feedlines (3m), while longer feedlines (15m) show significant power attenuation.

• Under 13.8V car charger supply, power output is slightly lower than with 15V power adapter supply, but the overall trend remains consistent.

Additional Notes:

• The RT97L has a theoretical maximum output power of 25W. However, actual performance may vary due to factors such as feedline loss, connector loss, and power supply conditions.

• We are actively optimizing the feedline solution to further enhance the overall performance of the RT97L Repeater.
