This is a video that provide the information about How find the resonance frequency and tune antenna wave traps. To find the resonance frequency we can use the wave traps. In this video, the wave traps is made of PVC pipe and the coils. Beside that, transceiver YAESU FT-897 or any HF receiver and grid dip meter are also required to find the resonance frequency and tune the antenna wave traps. By tunning the transceiver YAESU FT-897 we will find the resonance frequency. Here is the video :
