MDshelll Posted June 25, 2009 Share Posted June 25, 2009 salut, eu sunt din Cluj-Napoca e cineva din Cluj care stie sa calibreze o antena CB pe autoturism? Va multumesc mult. Quote Link to comment Share on other sites More sharing options...
yo9hnf Posted June 25, 2009 Share Posted June 25, 2009 -Problema se cheama "acordare" . Antena se acorda (pe o anumita frecventa)-Vezi ca antenele noi pt CB sunt deja acordate.Ca idee:Daca vrei sa faci o antena ground-plane de exemplu, o calculezi, iar pe langa calcul mai pui acolo cativa centimetri. Pui reflectometrul intre transceiver si antena, si incerci sa tai putin cate putin din ea pana reflectometrul arata unda reflectata minima.

MDshelll Posted June 25, 2009 Author Share Posted June 25, 2009 Doar ca nu am reflectometru. Antena care o am e Sunker Cb 2. Quote Link to comment Share on other sites More sharing options...
Guest radone Posted July 7, 2009 Share Posted July 7, 2009 Intrebare: Daca la o antena CB, imbrac tija intr-o izolatie de plastic? Va afecta emisia/receptia? Quote Link to comment Share on other sites More sharing options...
yo3ihg Posted July 7, 2009 Share Posted July 7, 2009 nu (nici la firele izolate pt dipoli nu afecteaza), dar de ce vrei s-o imbraci? raceste antena? Quote Link to comment Share on other sites More sharing options...
SirRoger Posted July 10, 2009 Share Posted July 10, 2009 nu (nici la firele izolate pt dipoli nu afecteaza), dar de ce vrei s-o imbraci? raceste antena? Cred ca de teama sa nu plateasca amenda pentru expunere indecenta a antenei Quote Link to comment Share on other sites More sharing options...
