Aktyèl pwen mezi: Ri nan yon distans sèten, fòs nan siyal ak ogmante distans oswa wotè antèn yo pral ondwaman; Ri a yon distans sèten, yo ogmante distans ak degre nan rediksyon oswa antèn, fòs siyal yo pral. Diminye monotonically. Kalkil teyorik bay Ri la ak HT wotè antèn, HR relasyon:

Actual measurement point: Ri of a certain distance, the signal strength with increasing distance or antenna height will be undulation; Ri at a certain distance, the distance increases with the degree of reduction or antenna, the signal strength will be. Decreases monotonically. Theoretical calculation gives the Ri and antenna height HT, HR relationship:
