Mcbazel Surecom SS11 Portable Field Strength Power Test Meter RF Signal Strength Test Meter with Antenna

-Frequency Range: 100KHz-3GHz (with antenna) -RF Sensitive: Max -40.97dbmv -Antenna (in) Interface: SMA Female -Battery built-in: 200mah Rechargeable Li-ion Battery -Size without Socket: 75 x 100 x 64mm -Built-in automatic damping function, which is the buffer function, prevents the needle from swinging too fast to cause damage. Instructions for use: Before use: -Please rotate the "amplitude adjustment" to the left most 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! -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! 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: 1x SS-11 Portable Field Strength Test Meter 1x SMA MALE UHF Telescopic Antenna 1x Micro USB Cable 1x English Instructions
