Full Wave Spaced
Electrical and Mechanical Specifications
•EXCELLENT CHOICE FOR MOST CLASS “C” stations.
Provides superior performance for stereo and SCA operations
due to its high VSWR rating.
•RUGGED CONSTRUCTION. The antenna system is fabricated
from rugged, heavy wall copper and naval brass. All joints are
tig-welded.
•PRESSURIZED AND GROUNDED. The antenna system is
pressurized to the feed point of each bay and each bay is DC
grounded.
•BEAM TILT AND/OR NULL FILL OPTIONAL. Custom vertical
patterns are available with center-fed arrays that have an even
number of bays.

based on the customer’s mounting structure, with FCC filing
documentation, are available.
•WEATHERIZATION (OPTIONAL).
Radomes or electrical
deicers available for areas that experience periods of heavy icing
and/or snow conditions.
•STANDARD MOUNTING BRACKETS. Fits up to 4” tower leg
or pipe. Supplied with antenna.

Notes:
1. Power gain figure is for each polarization.
2. Power rating is based on 40 degrees C ambient. Degeneration occurs
above 2000 ft.
3. Antenna weight, windload, aperture and dimensions are based on midband operation (98.1 MHz).
4. Antennas with 2 or more bays come with input fine-matcher.
5. SWR, Inc. maintains a continuous program of product improvement and
therefore reserves the right to change specifications without notice.
