What kind of antenna do you use on the second end (1.5km from MikroTik)?
And what do you call by “bad signal”?
there is installed 24dbi grid antenna and mikrotik groove…
you will have the best signal if you point directly at the front of the omnitik unit (because of the antenna pattern), and also the best gain of the omnitik antenna is in 5.4GHz. try to rotate the omnitik unit, so that it’s directly facing the client device, and your signal will be better. also try to change from 5.8 to 5.4GHz
antenna point direction is front of OmniTik unit currantly …and i m using 5.4Ghz

how is your groove antenna polarized, try to rotate it to horizontal polarization if you are on vertical
