    Default Diferente antene TRIAX TDS110 si TRIAX Unique

    Am vazut ca ambele antene (TRIAX TDS110 si TRIAX Unique) au performante foarte bune dar este o diferente de pret. Care ar fi diferentele intre antene? Unique are posibilitatea de a receptiona mai multi sateliti? Am vazut ca TDS 110 are suport multifeed pentru 4 sateliti.
    Mai concret pentrru un multifeed 0,8W-13E-19,2E care dintre cele doua antene ar fi mai potrivita (lasand la o parte diferenta de pret).

    Default update

    Am gasit cateva detalii: se pare ca e vorba de castigul constant al antenei pentru mai multe LNB-uri:

    http://www.triax.ro/triax-main-catalogue-2009.html

    "The Unique multi reception dish is the result of research into semi-parabolic shapes and the influence on available gain in both main and side directions. Through a special shaping we have stretched the focal point into a focal line and still letting each LNB utilize all of the dish’s surface, thus succesfully combining efficient area utilization of sidemounting with the broad and uniform
    azimuth beam coverage of the torus antenna."

    Pe de alta parte la 4LNB-uri problema e la limita: TDS 110 are castig 40,2dB iar Unique 37,1dB si pe ambele antene se pot pune 4 LNB-uri.

    comparatia castigurilor nu e tocmai ok, pt. ca la TDS 110 e 40,2 dB la o 11,7 GHz, iar la Unique ai 37.1 la 10.7GHz.. odata cu cresterea frecventei, creste si castigul pe o aceeasi antena .. deci la 11,7GHz Unique v-a avea un castig mai mare de 37.1, insa nu va ajunge la 40,2

    intr-adevar pe TDS ai castigul mai mare in focarul principal, insa scade pe masura ce te deplasezi fata de el .. la 10 grade in lateral cred ca ai mai putin decat iti poate da Unique care permite o deschidere de +/- 10 grade in conditii de receptie uniforma

    TDS110 cu suportul multi-feed promite receptie decenta intr-o plaja de 20 de grade (0,8V - 19,2 E de exemplu), iar Unique promite constanta a semnalului pentru o plaja de 30 de grade - conform catalogului din link-ul tau.
    Asta si constructia mai elaborata justifica diferenta de pret, nu ?
