NOTES:
  1.  Power gain figure is for each polarization.
  2.  Power rating is based on 40°C ambient. Derating occurs above 2000 Ft.
  3.  Antenna weight, windload and aperture are based on mid-band operation (98.1 MHz.).
  4.  Antennas wil beam tilt and/or null fill require an even number of bays and are center fed.
  5.  Antennas with 2 or more bays come standard with input fine matcher.
  6.  Antennas are supplied with mounting brackets for up to 4 inch diameter leg (uniform cross-section tower.).
  7.  For areas with heavy icing and/or snow conditions, optional radomes or electrical deicers are available.
