Question

If the height of transmitting and receiving antennas are 80 m each, the maximum line of sight distance will be: Given: Earth's radius =6.4 × 106 m (A) 36 km (B) 32 km (C) 28 km (D) 64 km

Maximum line of sight distance between two antennas, d M =√2 Rh T +√2 R ⋅ h R d M =2 × √2 × 6.4 × 106 × 80=64 km

Q. If the height of transmitting and receiving antennas are $80 m$ each, the maximum line of sight distance will be:
Given: Earth's radius $= 6.4 \times 1 0^{6} m$

$36 km$

$32 km$

$28 km$

$64 km$

Maximum line of sight distance between two antennas, $d_{M} = 2 R h_{T} + 2 R \cdot h_{R}$
$d_{M} = 2 \times 2 \times 6.4 \times 1 0^{6} \times 80 = 64 km$

Q. If the height of transmitting and receiving antennas are 80m each, the maximum line of sight distance will be: Given: Earth's radius =6.4×106m

36km

32km

28km

64km
