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! 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!
