Test suitable antenna for walkie talkie use. High sensitivity.
Frequency bandwidth: 1000KHz to 3000MHz. Measurement of radio field strength. The pointer amplitude can be adjusted (to protect the meter) ^^ It requires Amp to run the meter. Please ensure that the whip antenna is parallel with the polarity of the antenna you are reading. ^^ Please use different frequency antennas to test signals with different frequencies for better effect and sensitivity. The pointer amplitude can be adjusted (to protect the meter). ^^ If the field strength indicator indicates that the maximum range is exceeded, the "amplitude adjustment" can be adjusted to let the pointer indicate the appropriate position. ^^ If you have any problem with this unit, please check the appropriate section of this manual. If the problem is not mentioned, please feel free to contact us.
