QuickFire™ Windloading Information

Survival Table | Windloading
Gabriel antenna windloading and environmental ratings are listed below. The windload tables address all the windload criteria associated to the Standard and High Performance QuickFire models. In addition, you will find larger antenna diameter information for existing legacy products currently in operation worldwide.

Operational Temperature

Gabriel antennas are designed to operate at a minimum -40° F to +122° F (-40° C to + 50° C) per ANSI/TIA-222.

  1. Per ANSI/TIA-222.
  2. The above list of wind deflections applies to all sizes and frequencies. The ANSI/TIA operational wind speeds are never less than those listed in the table, but may be much higher. The allowable operational deflection for dish antennas is based on the antenna movement that would cause the signal to drop 10 dB. As the main beam of the antenna becomes wider, more deflection is allowed before the signal drops 10 dB. Smaller dishes and lower frequencies often have substantially improved operational wind speed. Check with your mWAVE – Gabriel and Mark Sales contact for specific information.
