High-Power OmniDirectional Antenna


The OMNI-A0184 is a high-powered antenna that operates over the 100 to 400 MHz frequency band with a VSWR of less than 3:1. The antenna has an excellent radiation pattern 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 antenna is consists of a dipole array which makes it groundplane independent.
