Hello everyone, last night i was testing my 145MHz Yagi antenna for VSWR value. I realized something stupid. When I was keeping the antenna close to ground, VSWR value was changing. Also, I stanted in front of the antenna same thing was happen. I search about that on internet but i am not be satisfied. If any one know the reason about this, could you tell me please. I will be really appriciated. Thanks a lot.
