Curiosity: ”increment” on the antenna
When interference occurs in the band, the causes can be different. But maybe you just call the bottom of the antenna “grew”… If mistletoe? But it doesn't grow on inanimate substrates… So I went up to the roof, and there I marvel – antenatal intercourse, antenna snapped onto the antenna ! 😮 … Well, they just had to be decent “experts” what did they install there? !!
