FM translator stations are subject to specific height (HAAT) and power limitations, which are regulated by the Federal Communications Commission (FCC). Here’s an explanation of these limitations:

If my construction permit specifies ERP only on the horizontal plane, does this mean I can’t use circularly polarized antennas like the Penetrator?
No, it does not mean that circularly polarized antennas like the Penetrator are illegal. LPFM stations are allowed to use circularly polarized antennas, as specified in §73.816(a) of the FCC rules. This regulation permits LPFM stations to use antennas with horizontal only polarization, vertical only polarization, circular polarization, or elliptical polarization. Therefore, you can use circularly polarized antennas like the Penetrator without violating the rules.
Why was my station authorized with a very low power level?
The power level authorized for your LPFM radio station might be due to several factors. Here are some common reasons for low power authorization for LPFM (Low Power FM) stations:
Could you explain the concept of a “contour” in broadcasting and clarify the distinction between a “50,50” and a “50,10” contour?
In broadcasting, a “contour” refers to a specific geographic area or boundary on a map that represents the coverage area of a radio station’s signal at a particular signal strength level. Contours are typically used to illustrate the extent of signal coverage for regulatory and planning purposes.
