High-performance 433 MHz Dome Antennas

What are the 433 MHz dome antennas?

The high-performance 433 MHz dome antennas are external through-hole screw mount dome/puck antennas that operate at a center frequency of 433 MHz, and the center frequency is 433 MHz antennas, which C&T RF Antennas Inc manufactures.

433 MHz dome antennas are compact, typically omnidirectional antennas designed for use in the RF 433 MHz frequency band, which is commonly used for various applications like remote controls, wireless sensors, wireless doorbells, sensor networks, and IoT devices.

These 433 MHz dome antennas are often characterized by offering a low-profile, space-saving design with a dome-shaped or puck-shaped appearance, and can be mounted externally, offering omnidirectional signal transmission and reception.

 

Besides the 433 MHz dome antennas, the 4G LTE 5G dome antennas, NB-IoT/LTE-M puck antennas, GSM 4G puck antennas, Wi-Fi puck antennas, GPS/GNSS puck antennas, and LoRa/ISM 868/915 MHz puck antennas are available at C&T RF Antennas Inc.

C&T RF Antennas Inc. offers a wide range of RF antennas, adapters, amplifiers, and cable assemblies. The internal & external antennas with Omni and directional antennas single-band/dual-band/multi-band/extra wideband radio frequencies such as 13.56 MHz, 169 MHz, 230 MHz, 315 MHz, 433 MHz, 868 MHz, 915 MHz, VHF&UHF, ADS-B, 2.4 GHz, 5 GHz, 1.2 GHz, 1.4 GHz, 1.8 GHz, 2G 3G 4G, 5G NR, etc.

Technical advantages and adaptability of high-performance 433 MHz dome antennas

Long-distance transmission capability

The 433MHz band wavelength is long (about 69cm), with strong bypass ability, transmission distance can reach hundreds of meters to 1km in the open environment, suitable for covering large industrial parks or open areas.

Low cost and high stability

The antenna has a low manufacturing cost and low power consumption of the 433MHz module, which is suitable for large-scale deployment.

RF signal stability, anti-jamming ability (especially in industrial environments, better than the 2.4GHz band), and suitable for high reliability requirements of the scene.

Flexible deployment and adaptability

Interface compatibility: Supports standard interfaces such as IPEX-1 generation, which can be quickly integrated into cabinets, control cabinets, and other equipment.

Ease of Installation: Compact design of screw mount and stick antenna, which can be directly fixed on the surface of the equipment or adjusted to the position by extension cables.

Environmental adaptability

Wide range of operating temperature (-40℃～+85℃), adapted to outdoor high temperature, low temperature, or humid environment to ensure long-term stable operation.

etc.
