modificare lungime antena

Recommended Posts

Salut Am cumparat o alarma pentru autoturism pe care vreau sa o folosesc in alta aplicatie.Ideea este ca vreau sa ii prelungesc antena. Ea are un fir de cu de cca 30 cm ca si antena. Alarma vreau sa o montez la o inaltime de cca 50 de cm de sol, si sa-i prelungesc firul pana la o inaltime de peste 2 metri si acolo sa-i pun in capatul firului o antena metalica de masina. Pot sa fac lucrul acesta? Parca citisem pe undeva caci daca ii modific lungimea antenei pot iesi din frecventa de lucru a telecomenzi?? E adevarat?As putea sa realizez lucrul acesta?(prelungirea antenei)
