Over-the-Air (OTA) television signals, sometimes referred to as terrestrial or conventional television signals, are radio waves transmitted from high towers to aerials mounted on homes or to small set top antennas.

While virtually left for dead ten years ago, OTA television has had a renaissance in North America over the last few years after governments in Canada and the United States legislated conventional television broadcasters switch their mode of signal transmission from 1950's era analog to 21st century digital.

In the United States, the switch from analog to digital signals occurred in 2009. In Canada, the switch from analog to digital television occurred on August 31st of this year.

Over-the-air Digital Television has become quite popular among Canadian home theatre enthusiasts because the stations are broadcast in high definition and are often superior to the same signals delivered via cable or satellite.

In the larger urban centres of Toronto and Vancouver, OTA viewers can often pull in ten or fifteen channels consisting of local television affiliates, Canadian network signals from CBC, CTV, and Global along with American network signals from ABC, CBC, FOX, NBC and PBS.
