VHF / UHF Line of Sight Calculator: Estimate Radio Communication Range

Calculate Your VHF/UHF Line of Sight Range

Enter the height of the first antenna above ground.
Enter the height of the second antenna above ground.

Calculate the maximum line of sight distance for VHF and UHF radio communication with our easy-to-use calculator. Understand how antenna heights impact your radio range for optimal signal transmission and reception, crucial for effective planning.

Formula:

D = 4.12 * (√h1 + √h2)
Where:
D = Maximum line of sight distance (kilometers)
h1 = Height of antenna 1 (meters)
h2 = Height of antenna 2 (meters)
