Radiation levels eye in the direction of the wave propagation is a flat suitable VHF.-or horizontal detection, which has a weakness, it is possible, not far beyond the horizon (because the stick arcs of the Earth) have or use a repeater station (Repeater) is intermittently.

Radiation levels in the eye The radiation level in the VHF. Ideal for - Transfer. Or detecting flat The weakness is that it did not go far beyond the horizon. (Because of the curvature of the earth) must be used or repeater station (Repeater) at intervals.

Wave propagation in the eye level is radiated wave in horizontal VHF. It is suitable in the transfer or แนวรา detection. The weakness is it not beyond the horizon (because the arc of the world). Have or use the repeater stations (Repeater) is periodically.
