I have created a very simple web application to help locate physical antennas in your area.
It is based on a public database provided by the Canadian government. I only extracted the data and created some very simple lists, with links to google maps to see where the antennas are located.
The database contains information of all Canadian, and some Americans and Mexicans antennas, for AM, FM, Television and also Sirius and XM terrestrial repeaters.
The utility is located here: http://www.fredericmalenfant.com/antenna
You will also get information on the power of the antenna and many other information.
I hope it may be useful to someone!
You can send me your comments on my contact page.
