Uhf receiver

Can someone explain to me why in a place with metals you create a signal shift of 200 khz from the main frequency which is 932.7 mhz ...? From a distance of 1-2 meters only do this.At this point that makes the difference there is also a magnetic anomaly..

thank you for sharing, the transmitted frequency increases or decreases by 200khz in the presence of the phenomenon ?

dear friends, all the construction was done with my 3d printer. Inside the box there is a logarithmic antenna 900mhz up to 2 ghz..The receiver is 100khz to 2 ghz ...

in points with copper a new frequency appears resulting from the displacement of the main frequency ...

the central frequency is from a gsm antenna in my area:χαχαχα:

I do not know what you are doing but when you approach metal a new frequency of 200 khz appears just above the main one, look at the orange circle in the photo
