I have written a Windows program that folks may find useful for aiming their TV antenna.
You can download it here:
TxFinder downloadI have tested it on Win 7 and Win 8.1.
Some features are:
- No internet connection needed
- Enter your location using zipcode or latitude and longitude
- Search for a city by name
- Maintain a listing of locations
- Displays both true and magnetic headings
- Includes listings of both Full and Low Power stations
For instructions click the Help button ('?') at the top of the window.
I don't know how current the data for the transmitter sites are, especially the low power sites.
As with any software, there are no guarantees.
I wrote this entirely for my own benefit and believe other people will benefit from it. Feel free to use it in any manner you see fit.
