porovnavat 17 a 11g je troška odveci..... 17G na dlhsie skoky je totalny nezmysel. Kto ma 17g vie ako sa to chova ked riadne zaprsi.

pre tych ktory si myslia ze 17tka je na viac ako 5km odporucam....

dostudovat fyzikalne zakony, pripadne vyuzit hentie vypoctove kalkulacky.

k postaveniu takeho spoja musi byt clovek bud uplne neznaly, alebo to musi byt maximalne ignorantske hovado... v 17ghz je povolenych 100mW EIRP, teda 20dBm, co znamena ze pri 60cm antene (zisk cca 38db) moze byt na vystupnom konektore zariadenia najvac -18 dBm..
http://www.teleoff.gov.sk/data/files/25921.pdf

pri dodrzani povoleneho vykonu, 60cm antenach, modulacii QAM256 a _ziadnej_ rezerve na unik je maximalny dosah spoja cca 1.9 - 2.0 km.. unikova rezerva 20db bude pri tejto vzdialenosti ak sa pouzije modulacia QPSK...

ak si ignorantske hovado kupi spoj s +22 dBm vystupnym vykonom a vydrbe to naplno aby mu to dopalilo na 20-30 km, EIRP je tam cca 1000 W, teda _desattisickrat_ viac nez je povolene.. desattisickrat.. desattisickrat!!!!!! kuafix..

nech hodi kamenom ten kto este neprekrocil povolenu rychlost... ale isto uznas ze je rozdiel, ci niekto v obci prekroci 50km/h o par km/h, alebo ci pojde _desattisickrat_ viac nez je povolene, teda 500 000 km/h - pre tych co si nevedia predstavit, je to blava-kosice za 3 sekundy.. to nie je trochu viac, to je proste fest brutalne a masakralne nad limit...

nedavno som sa na tuto temu bavil s jednym cechom a podla jeho slov CTU prave tieto 17ghz spoje s brutalne prestrelenymi vykonmi uz celkom riesi, a nema s tym ani vela roboty, nemusi to ani merat, pretoze tie spoje nie je mozne vobec technicky zregulovat do povoleneho vykonu, a konstrukcne zasahy do radioveho zariadenia su zakazane. takze ak je zariadenie na streche a je zapnute, rovno aj bez merania moze ist pokuta..

som rad ze tu ma niekto ešte kusok rozumu....

Ešte sa všetci tesime ako nam 17Ghz dobre chodi..lenze ked si tu vsetci zacnu stavat 20km spoje v 17tke na plne gule tak už nikomu nič nepojde.

Synchro nie je UBNT, ked to zaciti rušenie...ste dojazdili.

To iste je AF, vsetci sa tesia ze za malo penazi vela muziky. Len počkajte ked sa naplni pasmo a všetkym to prestane chodit.....
