Sirio WiFi and WiMAX antenna for 2.4 GHz, 5 GHz and multi-frequency systems
The 2.4 GHz WiFi antenna range includes a 2400-2485 MHz directional design, a 2300-2500 MHz omnidirectional design and a 1700-2500 MHz log-periodic version. The dual-band omnidirectional version operates at 2400-2485 MHz and 5150-5875 MHz, while the dual-band MiMo mini panel covers 2.4-2.5 GHz and 5.15-5.89 GHz. The WiMAX mini panel covers the 2.3-2.7 GHz and 3.3-3.8 GHz bands.
How do directional and omnidirectional antennas differ?
Omnidirectional versions provide 360-degree H-plane radiation. The 2.4 GHz omnidirectional design has a 22-degree E-plane beamwidth and 6 dBi gain. The dual-band omnidirectional version has E-plane beamwidths of 30 degrees at 2442.5 MHz and 20 degrees at 5512.5 MHz, with gain values of 4 and 6 dBi. The directional 2400-2485 MHz design provides a 33-degree E-plane beamwidth, 27-degree H-plane beamwidth, 15 dBi gain and a front-to-back ratio of at least 25 dB.
Antenna gain, SWR and polarization
Documented gain values range from 2.14 dBi to 15 dBi. The log-periodic antenna is specified with 9 dBd, or 11.1 dBi, gain, the WiMAX mini panel with 10 and 13 dBi, and the MiMo mini panel with 7 and 11.4 dBi. Depending on the design, the SWR limit is no more than 1.5, 1.6, 1.8 or 2. Polarization may be linear vertical, linear vertical or horizontal, or cross-polarized.
How should you choose a 2.4 GHz or 5 GHz WiFi antenna?
Selection should be based on the documented frequency range, radiation characteristics, gain, polarization, connector and mounting method in relation to the system requirements. Maximum power ranges from 5 to 50 W depending on the design and frequency band. The MiMo version uses 2 SMA male connectors on 30 cm low-loss cables, while other versions are equipped with SMA female, SMA male or N female connectors.
Antenna connectors, cabling and mounting options
Mast-mounted versions specify mounting diameters of 25-42 mm, 35-50 mm, 35-54 mm or 35-60 mm, and several antennas can also be wall-mounted. The wideband dipole designs include versions with an N female connector, as well as versions supplied with 5 m low-loss cable and an SMA male connector. The indoor adhesive-mounted antenna uses 3 m RG174 A/U cable with an SMA male connector and can be installed on glass, walls, wood and plastic surfaces, but not on metal surfaces.
What mechanical and environmental data should be considered?
Documented wind resistance for outdoor antenna designs ranges from 160 to 200 km/h. Operating temperature ranges are either -40 C to +80 C or -20 C to +80 C depending on the model. Documented materials include aluminium, stainless steel, brass, copper, fibreglass, ABS and UV-stabilized plastic. Certain wideband dipole versions have an IP67 rating.
Sirio antenna advantages and limitations
Advantages:
- The range includes omnidirectional, directional, log-periodic, mini panel, MiMo and wideband dipole constructions.
- Certain versions can be mounted on either a mast or wall, while the adhesive-mounted design can be installed on non-metallic surfaces.
Limitations:
- The adhesive-mounted indoor antenna cannot be installed on a metal surface.
- Frequency band, power rating, connector type and mounting dimensions vary by design.
