High-Power Wideband Antenna


The OMNI-A0221 is a high-power, wideband antenna designed for vehicle-mounted applications. The antenna operates from 20 to 3000 MHz separated into 2 bands; Band A covers 20 to 180 MHz and Band B covers 500 to 3000 MHz. Band A can handle full rated power continuously at all frequencies, making it ideal for all 100% duty-cycle applications. The insulated radiator is robust, hardwearing and impervious to fuel, oil and hydraulic fluid. The antenna is designed for direct mounting to ground platform with aid of grounding strap provided. The OMNI-A0221-01 is a low profile version of the OMNI-A0221 and is ideal for armed vehicles; however, it suffers from gain degradation at low frequency.
