In the Metric System


To calculate the line of sight comnunication range, and height of the CB antenna, and the height of the receiving antenna by using these formulas:


OR In the Metric System
For Example: If you are standing on your balcony at you high rise apartment at 28 floors above the ground or 336 feet above the ground with your walkietalkie, your line of sight talking range would be 25.9 miles. 6.47 miles = square root (2 x 5.5 feet) + square root (2 x 5 feet) 25.9 miles = square root (2 x 336 feet)
