Formula & Theory
LOS = 3.57(√h1 + √h2), Radio Horizon = 3.57√hThis formula is used to calculate antenna parameters for professional antenna height calculator.
Overview
Professional Antenna Height helps you calculate design values for a tower & structural project from Local Antenna Height, Remote Antenna Height, Operating Frequency. Calculate radio horizon, line-of-sight distance, optical horizon, wavelength, tower classification, and antenna coverage estimates. Use the result to make an informed first design decision before choosing hardware, setting dimensions, or evaluating the RF system in its final environment.
Input Guide
Enter Local Antenna Height, Remote Antenna Height, Operating Frequency exactly in the units shown by this professional antenna height. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.
- Local Antenna Height — use m.
- Remote Antenna Height — use m.
- Operating Frequency — use MHz.
Output Guide
The results describe the calculated professional antenna height values for the inputs you entered. Check each value against the available space, selected components, feed system, and operating conditions before making a final design decision.
How This Calculator Works
The Professional Antenna Height uses LOS = 3.57(√h1 + √h2), Radio Horizon = 3.57√h. Supply Local Antenna Height (m), Remote Antenna Height (m), Operating Frequency (MHz) in the displayed units, then use the calculated values as the first engineering target for this tower & structural design or analysis.
Design Notes
This tower & structural calculation is based on LOS = 3.57(√h1 + √h2), Radio Horizon = 3.57√h. Real-world accuracy depends on factors such as material properties, losses, mounting, nearby conductors, ground interaction, feed-line effects, and construction tolerance. Confirm the final system with measurement or simulation.
Build and Tuning Notes
Apply the professional antenna height result as an initial target, then validate it in the intended installation. Keep the physical layout and feed arrangement consistent while testing, change one parameter at a time, and record the measured outcome before making another adjustment.
Frequently Asked Questions
What does the Professional Antenna Height calculate?
Calculate radio horizon, line-of-sight distance, optical horizon, wavelength, tower classification, and antenna coverage estimates. The calculation provides an initial design value based on Local Antenna Height (m), Remote Antenna Height (m), Operating Frequency (MHz).
Which inputs are needed for the Professional Antenna Height?
