Operating principle and key features
The ANT 433-07M antenna belongs to the omnidirectional class (circular diagram in the horizontal plane). It converts electromagnetic waves into an electrical signal for the receiver and vice versa. With 7 dBi gain, it increases system sensitivity and increases range. Low standing wave ratio (SWR ≤1.5) ensures maximum energy transfer.
The N-female connector provides a reliable sealed connection. Linear polarization is selected during installation. The antenna is mounted on a mast or wall, withstanding strong winds up to 50 m/s. Corrosion-resistant materials guarantee long service life outdoors.
The antenna is compatible with radio channel systems LONTA-202 (Reef String-202), RIF STRING-200, RIF RING-701, as well as with any other receivers and transmitters in the 400–480 MHz range with a resistance of 50 Ohms. Ideal for central monitoring consoles, security alarms and telemetry systems.
