Pitakonan
meh 14 Watts konsumsi.
1W cukup kanggo jarak 1km. Nanging kita bakal nggawe 2W kanggo sampeyan kanggo njamin kinerja reception paling apik.
Iku uga gumantung ing lingkungan lokal, apa iku LOS utawa NLOS, mangga priksa video test kita, ana akeh jubin lan bangunan.
Kanggo ngganti amplifier daya beda babagan 500 MW, 1 watt, 2 watt, utawa 10 watt. Iku ora mung nyetel setelan ing piranti lunak, Sampeyan uga kudu ngganti hardware Power amplifier nang pemancar. Ora bisa operate lan ngganti ing pangguna pungkasan normal, lan biaya lan ukuran kothak logam pemancar beda.
Setelan frekuensi standar yaiku 503 MHz, 509 MHz, 521 MHz, lan 521 Mhz kanggo milih, tombol siji ing kabinèt bisa ngganti. Yen sampeyan butuh band 1.3Ghz mung, sampeyan kudu milih model liyane (1.2G utawa 1.4G). Mangga ngandhani rincian panjaluk sampeyan.
