The OMNI-A0187 is a high-powered antenna designed for vehicle applications in the 100 to 6000 MHz frequency band. The antenna may be used at frequencies as low as 80 MHz if a higher VSWR and lower gain can be tolerated. The fibre glass radome is equipped with spring mounting to allow whip-action and resistance to impacts and obstructions. Band A (100 to 500 MHz) is groundplane dependent and a ground strap is provided to aid with grounding. Bands B (400 to 3000 MHz) and C (850 to 6000 MHz) are ground plane independent.
