Eriali dielectric ni awọn pato ti o dara julọ pẹlu igbohunsafẹfẹ aarin ti 1575.42MHz ± 3 MHz lati rii daju gbigba ifihan agbara to dara julọ.VSWR jẹ 1.5: 1 ati bandiwidi jẹ ± 5 MHz, ni idaniloju asopọ iduroṣinṣin ati lilo daradara pẹlu awọn satẹlaiti GPS.Imudani 50-ohm siwaju sii mu gbigbe ifihan agbara pọ si.
Eriali naa da lori ọkọ ofurufu ilẹ 7x7cm ati pe o ni ere ti o ga julọ ti o ju 3dBic lọ.O pese agbegbe ere ti o dara julọ, ni idaniloju ere ti o kere ju ti -4dBic ni -90° ati +90° awọn igun, ti o bo diẹ sii ju 75% ti iwọn didun ohun elo naa.Polarization jẹ polarization ti ọwọ ọtún (RHCP), eyiti o mu gbigba ifihan agbara ṣiṣẹ lati awọn satẹlaiti ni gbogbo awọn itọnisọna.
