FAQ: My construction permit only lists an ERP on the horizontal plane. Does this mean that circularly polarized antennas like the Penetrator are illegal?
Select FAQ Category:
No. §73.816(a) clearly states that LPFM stations can run antennas that are:
- Horizontal only polarized.
- Vertical only polarized.
- Circularly polarized.
- Ellipitically polarized.
You can not run both a horizontal and vertical polarized antenna.
Therefore, circularly polarized antennas like the Nicom BKG-77 and others of the "penetrator" design are perfectly OK on LPFM either as single bay or multi-bay.
