Exact biquad de aceasta aveam si eu facuta... directionala aia ce ti-am zis ca i-am stricat la mainca-mea bol-ul ala de plastic cu capac pentru a o proteja de ploi si vreme urata.

Acestea sint dimensiunile unei antene biquad.Dimensiunile pot fi schimbate de fiecare in parte,in functie de materialul avut.
Sirma de cupru din imagine este de 1,5 mm,dar merge si sirma de 2...2,5 mm.
Laturile patratelor antenei sint de 32mm,dar merge perfect si cu 2,7...2,8cm.

Default Re: Antena biquad 14 dbi-wireless internet

E prima mea postare, si in primul rind vreau sa va salut.E in lucru prima mea antena( Biquad) si sper sa nu fiu dezamagit de rezultat.Dupa multe cautari pe net pe diferite forumuri,m-am blocat la dimensiunile reflectorului.Am gasit atitea poze si dimensiuni ca nu mai stiu pe care sa le aplic.Intrebarea mea e urmatoarea: care e dimensiunea reflectorului, si daca trebuie sa fie neaparat rotund? Eu am o placa PCB de L:160mm ,l:100mm. E buna? Multumesc anticipat

Nu te bloca la dimensiunea si forma reflectorului !
Fa-l din ce ai la dispozitie si testeaza.
Faptul ca dimensiunea si forma reflectorului nu sunt elementele capitale ale antenei o demostreaza tocmai lucrul ca ai gasit reflectorul in atatea variante.
Important e sa reusesti biquadul pentru ca acolo dimensiunile conteaza,sunt in legatura cu lungimea de unda si diametrul sarmei de cupru.

Sarma:2,5, laturile:31mm.Pina aici bine?

Sigur ca da ! Respecta prescriptiile din schema pusa de Kittmask
Dar performante o sa vezi numai daca testezi
Si daca nu iese din prima, mai incerci ...trebuie un pic de perseverenta.
La sfarsit o sa ai satisfactia lucrului facut de tine !

Default Re: Antena biquad 14 dbi-wireless internet

Nu vreau sa te intreb acuma ce placa wireless folosesti, dar tot ce pot eu
sa-ti spun e ca antenele "homemade" necesita o oarecare iscusinta si asa
cum am mai zis ,nu prea le reusesti din prima.E de ajuns o greseala si nu
obtii performante cu ele, ba din contra !
Acuma ,totul depinde de ambitia ta...
Am intrat de curiozitate pe 2-3 forumuri despre antene din Italia si Franta si
discutiile si pozele si help,help !...sunt interminabile.Unii,foarte putini, sunt
multumiti de ce le-a iesit, altii, banuiesc ca au abandonat...Asta e !

Ooo !Esti dotat corespunzator.De fapt se vedea lucrul asta din numarul mare
de retele pe care le prinzi.
In postul #2 e pozata antena biquad pe care banuiesc ca o vrei.
Poate reusesti sa o realizezi.Bafta

@diablo69 Ma bucur ca ti-a reusit.
Acuma , din pozele puse,vad ca ai realizat o Colliner Antena-antena omnidirectionala-dar ai postat in threadul antenei biquad-care e o
directionala.
Important e ca rezultatul iti da satisfactii.

Buna seara.Bine v-am gasit. Interesante informatii.M-ar tenta si pe mine sa incerc o antena.Cu ce nu sunt in clar -in centru,toate se leaga-lipesc pe o mufa -corect?Unde gasesc asa ceva?Ce fel de cablu se foloseste? Felicitari tuturor pentru ambitie si amabilitate.
An nou mai fericit!
