Sirio megawatt 4000 vs Sirio performer/turbo 5000
Posted: 04 Oct 2010 21:54
Nu stiu de ce Sirio 5000 are atat de mare succes, cind, cel putin mie, dupa ce am folosit ambele antene, mi s-a parut mult mai performant 4000-ul, fapt ce ma face sa-l folosesc si in continuare si sa il recomand cu mare incredere. Sa fi fost vreo problema cu 5000-ul meu? E drept ca dupa ce i-am facut un "upgrade" scotandu-i prima bobina, cea din montura in care intra mufa, antena a mers excelent, reusind (din spusele celui la care a ajuns in final) chiar o legatura la 60 km in camp deschis cu 4W (antena montata pe portbagaj la o berlina, prin gaurire, calibrata). Pe de alta parte, cu Megawatt 4000 montata intr-un plan de masa perfect, acopeream o mare parte din Bucuresti cu doar 1W, avantajul de aceasta data fiind inaltimea (monura de balcon). Alte plusuri la 4000 mi s-au parut spicul, mai subtire si mai lung, ce se poate plia la nevoie dupa bobina si nu cu tot cu bobina ca la 5000. Deasemenea, baza antenei respectiv sistemul de fixare pe masina sunt mult mai bune la 4000, cu filet tzeapan si nu cu un surubel de 4mm, cu care eu practic nu am reusit niciodata o montare ferma. In plus, la modelul "Turbo", sistemul de pliere cu sfera este un dezastru, antena cade imediat daca este atinsa sau chiar la vant/viteza, iar daca incerci sa o strangi mai tare, crapa toata carcasa bobinei.
