| Urcite ziadne dualne ozarovace na taku vzdialenost. Na trafficu nezalezi. Dolezite je SNR. Ked ta netrapia normy, tak na 18km spravis kludne 30mbit FD. Urcite pouzit vsak XR5 karty a riadne ich zredukovat, tak na 5-10dB |

| je lepsie pouzit na nstreme2 dve anteny kazdu v inej polarite ako jednu dualnu? teoreticky by to malo byt jedno ale niesom si tym isty... |

| Mame na jednom skoku nasadene dualne anteny kvoli zredukovaniu anten a teda aj najomneho ale na cca 6km, nie na 18km. Skor sa opytam aky ozarovac ides pouzit, to je podla mna tiez dost dolezite. Nechcem tu teraz od stola chytracit antena ako parabola je jedna vec ale myslim, ze doraz treba venovat ozarovacu. |
