Antenna Downtilt Angle Calculator

This page provides information about an antenna downtilt angle calculator, also referred to as an antenna tilt angle calculator.

The antenna downtilt angle calculator determines the distance based on the tilt angle, and conversely, calculates the tilt angle from the horizon distance.

It also outlines the formulas or equations employed in these antenna tilt angle calculators. The antenna downtilt angle calculator utilizes height (in feet) and distance (in miles).

• 1 mile = 1.60934 Km
• 1 Km = 0.6214 miles
• 1 feet = 0.3048 meters
• 1 meter = 3.28 feet
• 1 mile = 5280 feet

Antenna Downtilt Angle Calculator - 1

The following calculator determines the antenna downtilt angle based on the base antenna height, remote antenna height, and the distance between the antennas.

EXAMPLE of antenna downtilt angle calculator:

INPUTS:

• Hb (Base antenna height) = 120 feet
• Hr (Remote antenna height) = 80 feet
• Distance = 5.4 miles

OUTPUTS:

• Antenna downtilt angle = 0.08038 Degree

Antenna Downtilt Angle Calculator - 2

The following calculator calculates the distance between antennas based on the base antenna height, remote antenna height, and the antenna downtilt angle.

EXAMPLE of antenna tilt angle calculator:

INPUTS:

• Hb (Base antenna height) = 120 feet
• Hr (Remote antenna height) = 80 feet
• theta (Antenna downtilt angle) = 1 degree

OUTPUTS:

• Distance between antennas (in feet) = 2291.5
• Distance between antennas (in miles) = 0.434
