| niekde na nete som kedysik videl skript co ti vedel vyratat fresnelku na zaklade tychto udajov. okrem toho si to mozes podla mna vyratat aj sam...staci ti priblizne vediet vyzarovaci uhol anteny a vzdialenost. odhadom tipujem ze to staci (priblizne 100m vysoku prekazku v strede by podla mna signal mal vediet "preskocit") |

treba vyskusat ten spoj postavit a uvidi sa, ale prekazky na trase vedia riadne zneprijemnit zivot (hlavne ak su kovove alebo zmoknu  ) |
