Hello guys, i need help.Recently i bought this antenna to boost sinr, i already had good internet speed, but i had problems with sinr.Today i mounted antenna and expected my sinr to not drop under 10, because before antena it jumped to 20 and droped to 5.But with antenna almost nothing changed, rsrp get worse and sinr is not better.Rsrp before was -76 and now is -81.Im really struggling to find out why is this happening.
