Notes:
1. Power rating is based on 40 degrees C ambient. Degeneration occurs above 2000 ft.
2. Antenna weight, windload, aperture, and dimensions are based on mid-band operation (98.1 MHz).
3. Antennas with 2 or more bays come with input power divider.
4. Windload based on 50/33 psf.
5. SWR, Inc. maintains a continuous program of product improvement and therefore reserves the right to change specifications without notice.
