Strange weather radar lines

[urosale]

Hello, there are constant lines in Europe, over Bosnia and in last days over Croatia. I seen some circular strange formations people post here, but lines, never.
How is that possible and what is cause of them?

Hello,
This sort of spikes are due to interferences by WiFi sources.
