Dalam contoh ini akan kita coba lihat coverage pancaran dari
Digipeater YC1LZ-2 Longitude 6 43.94" South (atau -6.770833) Latitude 107 35.36" East (atau 107.625) Locator OI33TF27BW HAAT 1561 meter Antenna 4 dBi Omni Power 16 Watt Lokasi BNPB Tangkuban Perahu
Masukan Data Unit
Klik
File > Unit Properties
Masukan data
Name YC1LZ-2 Elevation(m) 1561 LAT LON or QRZ OI33TF27BW Lock di klik
Hasilnya akan tampak pada gambar
Masukan Data Peta
Klik
Files > Map Properties > Enter LAT LON or QRA
Masukan data
OI33TF27BW
Seperti tampak pada gambar
Pilih
Elevation Data Source > SRTM > Browse > Z:/home/onno/Geodata/srtm3
Atur lebar peta secukupnya. Default 50 km. Kita dapat memperlebar misalnya 300 km.
Height > 300
Jika semua sudah selesai klik
Extract
Semakin lebar peta / wilayah yang ingin di analisa, akan membutuhkan waktu lebih lama untuk download file SRTM yang dibutuhkan. Untuk frekuensi VHF kita bisa menganalisa untuk jarak 300 km-an jika kita pasang repeater di sebuah Gunung.
