DeLOCK 88877 Omnidirectional Antenna

The DeLOCK 88877 is an omni-directional antenna designed for devices with an SMA connector to operate in the ISM frequency band at 433 MHz. It provides a 3 dBi gain, 50 Ω impedance and vertical polarization in a compact black housing (30 × 30 × 150 mm), making it suitable for improving reception and transmission of 433 MHz signals in multiple directions.

Advantages

The antenna offers a simple SMA connection for easy installation, a moderate 3 dBi gain to increase signal strength in omni-directional coverage, and standard 50 Ω impedance for compatibility with common RF equipment. Its vertical polarization and compact size allow straightforward integration into wireless setups where space is limited.

Suitable for

• Wireless devices and modules with an SMA connector operating at 433 MHz
• ISM-band telemetry, remote controls and sensor networks
• Applications requiring omni-directional coverage in indoor or sheltered outdoor environments

How to use

Attach the DeLOCK 88877 to the SMA connector of your 433 MHz device by screwing the connector until secure. Position the antenna vertically to match its polarization and avoid placing it immediately adjacent to large metal objects that can obstruct signal propagation. Ensure the device and antenna meet local regulations for ISM-band transmissions before use.

Recommendations

For optimal performance, mount the antenna as high as practical and maintain clear line-of-sight where possible. If indoor coverage is insufficient, consider repositioning the antenna or using multiple antennas placed strategically to improve reception in specific areas.
