Directional horizontal plane patterns based on the customers mounting structure are available.
•WEATHERIZATION (OPTIONAL)
Radomes or electrical deicers available for areas that experience periods of heavy icing and/or snow conditions.
•WARRANTY
2-year limited warranty on defects and workmanship to the original purchaser.
Notes:
1. Power rating is based on 40 degrees C ambient. Degeneration occurs above 2000 ft.
2. Panel reflector is typically 72”, square flat panel (welded mesh over structural tube members – stainless or galvanized).
3. Antenna weight, windload, aperture, and dimensions are based on mid-band operation (98.1 MHz).
4. All antennas are supplied with custom mounting brackets, power dividers and cabling required for a complete functional array.
5. Windload based on 50/33 psf.
6. SWR, Inc. maintains a continuous program of product improvement and therefore reserves the right to change specifications without notice.
