100KHz1000MHz Field Strength Indicator Meter

1: The appearance is simple and efficient, beautiful and generous
2: Frequency bandwidth, high sensitivity, 100KHz-1000MHz (with antenna is 400-470Mz, please use different frequency antennas to test signals with different frequencies for better effect and sensitivity)
3: The pointer amplitude can be adjusted (to protect the meter)
4: Built-in automatic damping function, which is the buffer function, prevents the from swinging too fast and causing damage.
5: Small size, easy to carry, size: 90x115x70mm (excluding the raised antenna part)

6: Test sensitivity:
0.1w distance 0.1-1 meters
2W/5W , 1-3 meters range.
The 10W is in the range of 2-5 meters.
50W is about 3-10 meters.
With the HP8921A radio comprehensive tester, the sensitivity is -20dbm, and the -2dbm can be full. (The video rate is different and the sensitivity will be different)
Instructions for use:
Before use, please rotate the "amplitude adjustment" to the leftmost end. The length of the antenna to be pulled depends on the frequency of the test. It is better to have 1/4 wave as much as possible. The walkie-talkie is about one meter from strength meter. 't be too close! In order to avoid the signal is too strong to burn strength meter! Then press the walkie-talkie PTT button to make the walkie-talkie enter the launch state. At this time, the pointer of strength meter should have a signal indication. The stronger the signal, the greater the indication!
