Antenna ea dielectric e na le litlhaloso tse ntle haholo tse nang le maqhubu a bohareng a 1575.42MHz ± 3 MHz ho netefatsa kamohelo e nepahetseng ea matšoao.VSWR ke 1.5:1 mme bandwidth ke ± 5 MHz, e netefatsa khokahano e tsitsitseng le e sebetsang hantle le lisathelaete tsa GPS.Phetiso ea 50-ohm e boetse e ntlafatsa phetiso ea matšoao.
Antenna e ipapisitse le sefofane sa fatše sa 7x7cm mme se na le phaello e holimo ho feta 3dBic.E fana ka tšireletso e babatsehang ea phaello, ho netefatsa phaello e fokolang ea -4dBic ho -90 ° le +90 ° angles, e koahelang ho feta 75% ea molumo oa sesebelisoa.Polarization ke polarization ea letsoho le letona (RHCP), e ntlafatsang kamohelo ea mats'oao ho tsoa ho lisathelaete ka nqa tsohle.
LNA/filtara e tlatsana le dielectric antenna ho ntlafatsa ts'ebetso.Ka 28dB ea phaello (ntle le thapo) le palo e tlase ea 1.5dB ea lerata, e holisa matšoao a fokolang a GPS mme e fokotsa tšitiso ea lerata, ka hona e ntlafatsa ho hlaka le ho nepahala ha lets'oao.
LNA/filtara e boetse e na le lihloela tsa boleng bo holimo ho fokotsa tšitiso e kantle ho sehlopha.E fana ka bonyane ba 7dB ea attenuation ho f0+/-20MHz, bonyane ba 20dB ho f0+/-50MHz, le 30dB e tsotehang ea ho fokotseha ho f0+/-100MHz.Sena se tiisa hore ho na le lets'oao la GPS le hlakileng le la boleng bo holimo, esita le libakeng tse tletseng lerata.
VSWR ea LNA/filthara e ka tlase ho 2.0, e netefatsang tahlehelo e tlase ea ho khutla ho eketsa ts'ebetso ea phetisetso ea mats'oao le ho fokotsa phokotso ea mats'oao.
