Mlongoti wa dielectric uli ndi mawonekedwe abwino kwambiri okhala ndi ma frequency apakati a 1575.42MHz ± 3 MHz kuti awonetsetse kuti ma signature alandila bwino.VSWR ndi 1.5:1 ndipo bandwidth ndi ± 5 MHz, kuwonetsetsa kulumikizana kokhazikika komanso koyenera ndi ma satellite a GPS.Kulepheretsa kwa 50-ohm kumawonjezera kufalitsa kwa ma siginecha.
Mlongoti umakhazikitsidwa pa ndege yapansi ya 7x7cm ndipo ili ndi phindu lalikulu kuposa 3dBic.Imapereka chidziwitso chopindulitsa kwambiri, kuwonetsetsa kupindula kochepa kwa -4dBic pa -90 ° ndi +90 ° angles, kuphimba kuposa 75% ya voliyumu ya chipangizocho.Polarization ndi kumanja kwa circular polarization (RHCP), yomwe imakulitsa kulandila kwa ma sign kuchokera kuma satellite mbali zonse.
LNA/sefa imakwaniritsa mlongoti wa dielectric kuti upititse patsogolo magwiridwe antchito.Ndi 28dB yopindula (popanda chingwe) ndi phokoso lochepa la 1.5dB, imakulitsa zizindikiro zofooka za GPS ndikuchepetsa kusokoneza kwa phokoso, potero kumawonjezera kumveka bwino ndi kulondola.
LNA/sefa ilinso ndi zosefera zapamwamba kwambiri kuti muchepetse kusokoneza kwakunja.Imapereka 7dB yocheperako pa f0+/-20MHz, osachepera 20dB pa f0+/-50MHz, ndi 30dB yochititsa chidwi ya kutsika pa f0+/-100MHz.Izi zimatsimikizira chizindikiro chomveka bwino komanso chapamwamba cha GPS, ngakhale m'malo odzaza ndi phokoso.
VSWR ya LNA/sefa ndi yochepera 2.0, yomwe imatsimikizira kutayika pang'ono kubwereranso kukulitsa mphamvu ya kufalitsa ma siginecha ndikuchepetsa kutsika kwa ma sign.
