400 MHz antennas are most commonly used within public safety, SCADA and mobile radio applications. In the United States, 433 MHz are typically used for water metering, gas metering and other applications requiring underground connectivity. It is harder for higher frequencies to pass through other areas. Antenova's 400 MHz antennas are designed to maintain communications over long distances and within difficult terrains, even underground.
