    ha ha

    In mai putin de 10 minute am facut antena asta, nu am calculat nimic, doar am urmarit marimile aproximative (la ochi) din filmulet si... se comporta exemplar

    Foarte tare frate

    Nuuuuu
    Nu ma mai bucur de ea...

    Am luat un amplif AM-417 facut de Alcad http://antech.ro/thumbs.html?foto/p8...arg/AM-417.jpg

    cu sursa aferenta, desigur

    si

    a fost montata una bucata dipol de 232 mm (pe asta l-am avut de-a gata, doar bucla i-am facut-o) in pod si.... s-a intamplat ! Am prins in conditii bune Romantic Fm (101,9) cu RDS, plus o duzina de alte posturi radio de care nu aveam habar cu ce am incercat inainte...

    M-am tot gandit cum sa fac o antena cu dipol de 145-150, dar, din lipsa de materiale, talent si timp, am comandat una de-asta http://www.dipolnet.ro/antena_fm_dip...mhz__A0312.htm
    Care e cam mare si de la care chiar am asteptari
    Si cu care cred ca o sa inchid instalatia, cu scopul(rile) atinse...

    Excelent amplif-ul si foarte versatil.
    Atentie la polarizare si in FM in functie de ce vrei sa prinzi.
    Te poti informa si orienta aici.

    Sau de la amicul RVIC
