Wideband VHF/UHF Vehicle Antenna


The OMNI-A0081 is a high-power wideband antenna designed for high-power applications in the 100 to 520 MHz frequency band and recently upgraded for high-power handling and improved gain.brThis omni-directional antenna has an excellent radiation pattern, no pattern break-up, and a consistently low VSWR across the entire frequency band. It can handle full rated power continuously at all frequencies, making it ideal for all 100% duty-cycle applications. The anodised aluminium radiator is equipped with spring mounting to allow whip-action and resistance to impacts and obstructions.brThe antenna may be used at frequencies as low as 80 MHz if a higher VSWR and lower gain can be tolerated.brThe antenna is designed for direct mounting to ground platform with aid of grounding strap provided.
