The following are the reasons for the low RT90 power：
2.The quality of the feeder
3.Whether the machine has high power output
4.Power line output voltage level（The standard voltage used for the test is DC13.8V，If the voltage is tested with DC11.5V-12V, the data obtained is UHF at around 23W, VHF at around 30W, and the measured power is generally low.）
