A transmitting antenna at the top of a tower has a height of 20m and the height of the receiving antenna is 45m. Calculate the maximum distance between them for satisfactory communication in LOS mode. (Radius of the Earth `= 6.4 xx 10^(6)` m)

Explanation

To solve the problem of calculating the maximum distance between a transmitting antenna and a receiving antenna for satisfactory communication in Line of Sight (LOS) mode, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Height of the transmitting antenna, \( H_t = 20 \, \text{m} \)
- Height of the receiving antenna, \( H_r = 45 \, \text{m} \)
- Radius of the Earth, \( r = 6.4 \times 10^6 \, \text{m} \)
