Abstract
NOAA is a remote sensing satellite that contains informations about the earth, such as mapping land, sea and reporting weater conditions, cloud conditions and hotspots in an area. NOAA satellite works at the downlink frequency of 137-138 MHz. Double Cross Dipole antenna can be used as signal receiver antenna from NOAA satellite. Double cross dipole antenna is design to operate at frequency range of 137-138 MHz. simulation result of 137.62 MHz frequency generate return of loss as -20.726 dB, the value of VSWR 1.20 bandwidth of 82.32 Mhz, omnidirectional polarization and circular polarization. The result of measurement of double cross dipole antenna it was obtained return loss as-18.911 dB, value of VSWR of 1.255, bandwidth of 32.813 MHz. Double cross dipole antenna can be used to receive NOAA satellite signal in a form of voice. Voice data can be converted into image with the help of WXtoImgsoftware. The result of conversion was in a form of cloud condition in Indonesia area.
