Feature:
1. Suitable for detecting radio waves of 20mhz‑6.5ghz, and the sensitivity is very high and adjustable.
2. This RF signal level meter can detect weak signals of mw level and detect suspicious electric wave signals.
3. Built‑In automatic damping function, that is, the buffer function, can prevent the needle from swinging too fast and causing damage.
4. Uses sophisticated production technology, has excellent performance, and can be used for radio antenna radiation.
5. Made of high‑quality materials, this RF signal level meter is sturdy, durable, not easily damaged, and has a long service life.


How to Use:
Instructions for use:
Please rotate the "Amplitude Adjustment" to the left end before use. The length of the antenna to be pulled depends on the test frequency. It is best to have as many quarter waves as possible. The handheld walkie‑talkie is about one meter away from the field strength meter. Don't get too close, so as not to burn the field strength meter if the signal is too strong. Then press the PTT button of the walkie‑talkie to make the walkie‑talkie enter the transmitting state. At this time, the pointer of the field strength meter should be signaled. The stronge the signal, the greater the indication.
Amplitude adjustment:
