The Haigh-Farr Flexislot™ antenna offers unique mounting capabilities, is designed for simple installation and retrofit on flat, cylindrical and conical shaped bodies, and provides broad-beam E-plane pattern coverage. Designs are available from 300 MHz to 13 GHz.

The Flexislot™ is a building block element and may be arrayed to provide either directive beam shapes or wider spherical coverage. If more than one Flexislot™ is used, the necessary power divider circuitry may be contained within one of the elements, or provided as a separate device.

Haigh-Farr also manufactures the necessary cabling to feed multi-element systems. All multi-element configurations are tested as a system, including measuring the radiation patterns.


The Flexislot™ may either be flush mounted or mounted directly to the exterior of the vehicle, and may be secured to the vehicle using mechanical fasteners and/or adhesive bonding agents.

The antenna may be mounted inside a radome for enhanced ruggedization. For high aero-heating applications an ablative heat shield may be added.
