Antenna ya dielectric ifite ibisobanuro byiza cyane hamwe na centre yumurongo wa 1575.42MHz ± 3 MHz kugirango hamenyekane neza ibimenyetso.VSWR ni 1.5: 1 naho umurongo wa 5 MHz, uhuza neza kandi neza na satelite ya GPS.50-ohm impedance irusheho kongera ibimenyetso byohereza.
Antenne ishingiye ku ndege y'ubutaka ya 7x7cm kandi ifite inyungu zingana na 3dBic.Itanga inyungu nziza cyane, yemeza inyungu ntoya -4dBic kuri -90 ° na + 90 ° inguni, ikubiyemo hejuru ya 75% yubunini bwibikoresho.Ihindagurika ni ukuboko kw'iburyo kuzenguruka polarisiyasi (RHCP), itunganya neza kwakira ibimenyetso biturutse kuri satelite mu mpande zose.
LNA / muyunguruzi yuzuza antenne ya dielectric kugirango irusheho kunoza imikorere.Hamwe na 28dB yinyungu (idafite insinga) hamwe na 1.5dB yerekana urusaku ruke, byongera ibimenyetso bya GPS bidakomeye kandi bigabanya urusaku rw urusaku, bityo bikongerera ibimenyetso neza kandi neza.
LNA / muyunguruzi nayo igaragaramo ubuziranenge bwo muyunguruzi kugirango igabanye hanze ya bande.Itanga byibuze 7dB ya attenuation kuri f0 +/- 20MHz, byibuze 20dB kuri f0 +/- 50MHz, hamwe na 30dB ishimishije kuri f0 +/- 100MHz.Ibi byerekana ibimenyetso bya GPS bisobanutse kandi byujuje ubuziranenge, ndetse no mubantu benshi kandi basakuza.
VSWR ya LNA / muyunguruzi iri munsi ya 2.0, yemeza igihombo gike kugirango igabanye ibimenyetso neza kandi igabanye ibimenyetso.
