There is high hill on direction of 230 degree, and our main route located on behind this high hill. From google earth elevation profile measurement the residential more high 100 metres from the site Desa Madang M-D-GF.

This route is lower than with the high house as explain from the picture above.

Azimuth : 210 Degree Azimuth : 240 Degree



This land profile explain about the reason why Bogor Paten M-P-GF is more dominant to cover the residential than Desa Madang M-D-GF. Bogor Paten is more LOS (Line of Sight) to cover than Desa Madang.

Desa Madang is lower than the residential area as our main route. From land profile and panoramic photo, Desa Madang can't more dominant the residential.
