Product advantages:
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 needle from swinging too fast and causing damage.
5: Small size, easy to carry, size: 90*115*70mm (excluding the raised antenna part)
6: Test sensitivity:
0.1w transmitter distance 0.1-1 meters
2W/5W transmitter, 1-3 meters range.
The 10W transmitter 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 handheld walkie-talkie is about one meter away from the field strength meter. Don’t be too close! In order to avoid the signal is too strong to burn the field strength meter! Then press the walkie-talkie PTT button to make the walkie-talkie enter the launch state. At this time, the pointer of the field strength meter should have a signal indication. The stronger the signal, the greater the indication!
Amplitude adjustment:
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.
Method for testing the maximum gain point of an antenna
1. In order to change the frequency conveniently and quickly, you should use the keyboard to set the frequency walkie-talkie manually.
2. Link the walkie-talkie and antenna feeders, place the field strength meter near the antenna (depending on the environment), place it within the vertical radiation angle of the antenna as much as possible, and the antenna planning method is best.
3. Set the frequency of the walkie-talkie, press the launch button, observe the meter reading, and register the meter reading. Then set the walkie-talkie to other frequency points, let the walkie-talkie enter the launch state again, observe the meter reading... and then compare the readings of each frequency point! You can know the best frequency/segment of the antenna under test!
Package include:
1 x Field Strength Indicator Meter
1 x Antenna
