What are considered low-power FMs in Canada?
A. In Canada, there are two classes of low-power FM broadcasting stations: very low-power FM (VLPFM), which normally allows up to 10 W effective radiated power (ERP) in any direction; and low-power FM (LPFM), which normally allows up to 50 W ERP. The ERP is equal to the transmitter power supplied to the antenna multiplied by the relative gain (dipole) of the antenna in a given direction in consideration of the transmission line losses. Generally, VLPFMs are only allowed in remote areas.
