What frequency band to select (Low or High) in wattmeter for an accurate measurement between 25-30 Mhz ?

When measuring power between 25-30 MHz, both the Low and High bands are capable of providing accurate readings within this frequency range. However, the selection should depend on the power level of the signal you're measuring. The Low band is designed for higher power measurements, with a range of 10-10,000 W, while the High band is intended for lower power levels, covering 1-1,000 W. For optimal accuracy, choose the band that best matches the power level of your application within this frequency range.
