Omni-A0100 is a directional antenna designed for monitoring horizontally polarized RF signals in the frequency range 500 to 3000 MHz.
The band is covered by two antenna arrays mounted under a single compact radome. They each consist of 8 dipoles combined in phase around the mast.
Generous central cavity space allows several large cables to be passed through the antenna for feeding other bands, or DF antennas higher up the stack. Substantial mast and flanges allow for heavy antennas to be mounted above the OMNI-A0100.
Antenna is part of the SYST-A0004 stack, providing interferometry DF, vertical, and horizontal polarization monitoring in the frequency range 20 to 3000 MHz.
