Basic antenna ANT 433-07M

Choose the high performance ANT 433-07M base antenna for your fixed radio systems!

Ensure maximum range and stability of signal reception. The ANT 433-07M antenna is designed to work with receivers LONTA-202 (Rif String-202), RIF STRING-200, RIF RING-701 and other radio devices in the 400–480 MHz range. 7 dBi gain significantly expands the coverage area. The circular radiation pattern guarantees uniform reception from all sides. Order a reliable antenna for your security and telemetry system.

• High gain 7 dBi. Increases the communication range and improves the quality of reception of weak signals.

• Wide frequency range. Operates in the ranges 426–445 and 460–480 MHz, customization is possible.

• Low SWR no more than 1.5. Guarantees minimal power loss and efficient matching.

• Durable all-weather construction. PVC flask, aluminum glass, stainless steel fastening, wind resistance up to 50 m/s.

• High permissible power 100 W. Compatible with powerful transmitters and repeaters.

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.
