Dipole Antenna 433 RX (custom-made for any frequency from 250 MHz to 2.8 GHz)

Brand: BombAss. Product type: Antennas > Dipole Antennas. Professional dipole antenna for reception with an operating frequency range from 250 MHz to 2.8 GHz, custom-made for a specific operating frequency. This versatile receiving element is suitable for both amateur and industrial solutions where stability, reliability, and precise resonance tuning are crucial.

Key Features

• Frequency range: any frequency from 250 MHz to 2.8 GHz (custom-made)
• Bandwidth: 40 MHz (VSWR < 1.5)
• Connector type: IPEX1 (1.13 mm)
• Cable length: 10/15 cm (both options available)
• Radiation pattern: toroidal
• Gain: 2.15 dBi
• Moisture resistance: IP65

The antenna is designed for outdoor use: IP65 protection class ensures resistance to dust and moisture in moderate conditions, allowing it to be used in outdoor installations and protected enclosures. The short cable length of 10 or 15 cm simplifies installation in compact receivers and modules, and the IPEX1 (1.13 mm) connector guarantees compatibility with popular boards and receiving modules.

Technical Details and Tuning

A bandwidth of 40 MHz with VSWR < 1.5 ensures efficient reception at the selected frequency with minimal reflected waves. The 2.15 dBi gain makes the antenna optimal for reception without additional complex amplifiers, with a minimal amount of spurious signals. To achieve ideal performance, each antenna is tuned with a vector analyzer for precise resonance adjustment and VSWR minimization, which is especially important in conditions of dense spectral load or when maximum receiver sensitivity is required.

Applications

• 433 MHz receiving modules and adjacent bands
• Radio equipment for remote control and telemetry
• Amateur radio projects and industrial wireless systems
• Integration into compact devices where protection and reliability are important

Technical specifications and the possibility of individual tuning make this BombAss dipole antenna a versatile solution for a wide range of tasks: from amateur projects to professional telemetry and industrial systems.
