Haigh-Farr Button antennas were designed for applications where size and weight are critical, covering frequencies from 2.2 GHz to 9.6 GHz. All Button antennas provide the omnidirectional coverage of a stub in a rugged package, with Model 2107 being designed to fill in the overhead null.

All Haigh-Farr Button antennas utilize well-proven materials and methods of construction. Superb protection is obtained through the use of a high-impact, high-temperature radome, with excellent properties in environments containing moisture and contaminants found in airborne applications.

Mounting is accomplished through a "D" hole in the vehicle. The antenna is secured using a lock washer and nut with vehicle sealing achieved through an integral O-Ring.
