In this case the broadcast antenna height used for calculations should be the antenna height above average terrain (HAAT). First, determine the antenna height. And don’t get too fixated on the height of the TV antenna, several factors will determine a clear signal reception. Rescan your channel monthly. An antenna is a great way to watch 100% free HD TV from networks like ABC, CBS, FOX, and NBC. It determines the range of an antenna based on several key factors: transmit power, cable loss, transmit antenna gain, and receiver sensitivity. Move the antenna to a new location or height frequently, if you are using an indoor one. Antenna coverage refers to the geographical area where reliable radio signals can be transmitted or received from an antenna. The antenna downtilt and coverage calculator (aka antenna tilt angle calculator) is used to determine the approximate downward angle, measured in degrees, which the transmitting antenna is to be positioned for optimal signal strength and coverage. The Balun matches the Balanced Antenna into the Unbalanced Line Of Sight Calculator calculators, engineering calculators. This antenna coverage and tilt angle calculator also provides, given a beam width, the inner and outer radii of beam's coverage. Antenna Height Above Average Terrain (HAAT) values for a particular FM or TV station can be obtained from the FM Query or the TV Query, or use the HAAT Calculator. Enter the elevation and antenna height in the calculator. Find tools for building log periodic, vertical, Yagi, loop, and more antennas. Dipole Antenna Calculator The measurements below are for building a simple Dipole Antenna. it assumes there is nothing between the radio signal and the antenna horizon. Antenna Height of 1st Station (ASL) Antenna Height of 2nd Station (ASL) Feet Metres For the 1st station, the Radio Horizon is away. Wondering how high to mount your TV for the best viewing experience? Enter your TV size and seating distance, and our Advanced TV Mounting Height Calculator will find the perfect height for you with ease. Please wait a few minutes to see if the reception is getting better before the move. this line of sight calculator calculates the distance of the horizon from an antenna placed at a specific height. With a protractor or other method draw bearing lines from the antenna at angles of 0, 45, 90, 135, 180, 225, 270 and 315 degrees. Values for antenna height above average terrain (commonly abbreviated "HAAT") can be calculated using this form. For the 2nd station, the Radio Horizon is away. You will see the actual line of sight distance to the horizon in the "Distance" section before the radio waves are attenuated by the curvature of the Earth. the calculator also calculates the radio horizon. com To use the calculator, simply type in your antenna height above ground in the appropriate window below and click the "Compute" button. . Enter the two antenna heights in meters, feet, kilometers or miles and read the maximum range (r) between the antennas also in meters, feet, kilometers or miles. A few times a year atmospheric conditions cause a ducting effect extending radio horizon. Then you can find out where the broadcast towers are in your local. This page provides an antenna range calculator as part of a suite of converters and calculators. 6 days ago · The Antenna Calculator aims at delivering a comprehensive and practical tool to Antenna Engineering students and practitioners. The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun. Input height of the TV tower and height of your antenna This calculator calculates the line of sight distance between the transmitter and receiver, and the radio horizon for a given height of the antenna (in metres). In Sep 28, 2025 · Calculate the LOS, Line of Sight, distance between two antenna setups. Aiming your antenna at TV tower can improve reception. to get the maximum line distance, you need to enter the height of the antenna. The Line of Sight calculator will determine both the "line of sight distance" and "radio horizon / service range" of an antenna placed at a specific height above the ground, represented by "antenna height (h)" in this equation. It's a quick and easy way to find digital television transmitters (DTVs) nearest to your location. Antenna Height Calculator The Antenna Height Calculator feature takes the information from the GPS option, whether you use a quick release and the height of the survey pole all into account when calculating the total height at the end. We present the basic theory and rigorously validated calculators to analyze and design numerous antenna types and related components. The total line of sight distance is Miles Km. iCalculator Physics Line Of Sight Calculator Radio Line of Sight Calculator In radio communications, the line of sight (LOS) is the direct, unimpeded path that an RF (radio frequency) signal takes from the transmitter to the receiver. We strive to ensure the accuracy and updating of the information and calculations provided, but we make no warranties or Find your nearest digital TV transmitter with Antennas Direct's mapping tool. Use our TV height calculator to find the right height to mount your TV for the most comfortable viewing experience. It is primarily determined by the antenna's height and environmental factors.
