    Default Sfaturi antena wireless

    As dori sa construiesc o antena wireless in banda de 2,4Ghz. As dori sa stiu ce tipuri de antene se pot construi si daca pot folosi o antena simetrica (parabola) pentru a acoperi o arie cat mai mare, as dori sa stiu cum se poate face un feeder pentru o parabola de 1,5m.

    Distanta aproximativa ar fi de circa 1km in linie dreapta, fara obstacole, in mediu urban, dar as prefera ca distanta sa fie si mai mare.

    I-ti recomand sa cumperi o antena de fabrica , la fregvente mari (2,4GHz) este destul de greu sa o construiesti din motive de tolerante .

    Iti recomand sa cumperi Antena Grid California Amplifier 24 dBi/2.4 GHz ! se foloseste cel mai mult .. de ce? simplu .. are cel mai bun castig !Eu folosesc in acest moment una si sunt super multumit de ea .. !Am reusit conexiune in cealalta parte a orasului .. unde era un Acces point tot cu o astfel de antena !

    Pe langa antena asta am mai testat si antena Yagi cu 9 elemente homemade,antene omnidirectionale ,si chiar diferite "palnii" facute de diversi .. in 2,4 .. dar nu se compara cu performantele Antenei Grid California Amplifier 24 dBi/2.4 GHz!

    Foarte important :

    Daca doresti sa obtii performante .. iti recimand sa pui cablul cat mai scut intre antena si AP ,sau .. daca e necesar sa folosesti cablu de foarte buna calitate .. de exemplu H-1000, pe de alta parte mufele de conexiune ( mufe N) sa fie de calitate !Nu se accepta aici lipituri ,imbinaturi sau alte cele!

    Antena de care ti-am vorbit o gasesti aici : http://www.wifitrading.ro/index.php?...mart&Itemid=26
