Part of the Alaris Antennas product range

This is an extremely wideband, compact, active horizontally polarised receiving antenna for omnidirectional monitoring. It is designed for either static use on shelters or can be installed on vehicles. Mounting is via the provided standard NATO and US 4/6 hole mounting flange, making it compatible with a variety of standard mounting arrangements. The OMNI-A0156 and OMNI-A0156-02 variants of the antenna provide 2 output ports which exit the antenna under the mounting flange for watertight and convenient vehicular installation. One output port covers the band from 20 to 1000 MHz and the second from 1000 to 3000 MHz. The OMNI-A0156-01 combines the two bands internally and provides a single output connector.brThe OMNI-A0156 and OMNI-A0156-01 versions are equipped with active matching and amplification, which provides excellent performance at very low frequencies. The OMNI-A0156-01 provides a passive bypass feature to allow the antenna to be used in passive mode in high field strength environments by removing power to the antenna.brThe active versions of the antenna can be powered using a product such as the MISC-A0022.brThe antenna is excellently twinned with the OMNIA0098 active VP monitoring antenna to provide full spectrum coverage of both VP and HP signals.
