2,4Ghz and 5Ghz WiFi Antenna from other Brands

2.4 GHz and 5 GHz WiFi antenna - main technical characteristics

The WiFi antenna configurations in the category differ significantly in their technical parameters. The documented gain of the 2.4 GHz indoor antennas is 2 dBi, while the dual-band 2.4/5 GHz indoor version is specified with gain up to 3 dBi. The 5 GHz outdoor base station antenna has a documented gain of 15 dBi. All documented antennas have an impedance of 50 ohm.

What frequencies are used by the 2.4 GHz antenna and 5 GHz antenna configurations?

The 2.4 GHz antenna solutions are designed for operation in the 2.4 GHz band, while the dual-band version supports both 2.4 GHz and 5 GHz operation. The category also includes a dedicated 5 GHz outdoor antenna. When selecting an antenna, the operating frequency of the connected WLAN device should therefore be compared directly with the documented frequency of the antenna.

WLAN antenna for indoor and outdoor use

The documented WLAN antenna range includes solutions for both indoor and outdoor applications. The 2.4 GHz antennas with 2 dBi gain and the dual-band 2.4/5 GHz antenna with gain up to 3 dBi are specified for indoor use. The 5 GHz base station antenna with 15 dBi gain is designed for outdoor installation and has an IP67 protection rating.

Indoor and outdoor WiFi antenna configurations

The indoor antenna range includes compact direct-connect and magnetic-mount solutions. The direct-connect version has documented dimensions of 94 x 8 x 8 mm and is made from UV-resistant plastic in white. The magnetic-mount antennas are made from black UV-resistant plastic, with a total length of 12 cm, while the dual-band version has a total length of 9 cm.

How does the indoor omnidirectional antenna connect?

The connector type of the omnidirectional antenna depends on the design. The compact 2.4 GHz antenna uses an MMCX connector. The magnetic-mount 2.4 GHz and 2.4/5 GHz versions include a 1.5 m RG-174 cable with an RPSMA male connector. The cable length and connector type should therefore be checked against the connection requirements of the WiFi device before installation.

Magnetic-mount WiFi antenna with RG-174 cable

• 2.4 GHz omnidirectional version: 2 dBi gain.
• 2.4/5 GHz omnidirectional version: up to 3 dBi gain.
• Impedance: 50 ohm.
• Cable: 1.5 m RG-174.
• Connector: RPSMA male.
• Designed for indoor use.

The dual-band magnetic-mount version has a documented IP50 protection rating. The category page does not specify the same IP rating for the 2.4 GHz-only magnetic-mount antenna, so this protection rating should not be generalized across both designs.

Documented parameters of the 5 GHz outdoor WiFi antenna

The 5 GHz outdoor WiFi antenna uses an omnidirectional base station design. It has an impedance of 50 ohm, gain of 15 dBi, and dual H+V polarization. The connection is provided by 4 N female connectors. The housing is made from UV-resistant polymer and has a documented IP67 protection rating.

Which mechanical data apply to the 5 GHz antenna design?

The documented dimensions of the 5 GHz antenna are 492 x 80 mm and the weight is 1110 g. Wind resistance is specified as 200 km/h. Mounting is carried out with a double clamp, and the maximum supported mast diameter is 57 mm. These parameters should be checked directly against the available installation location and mast dimensions before installation.

Antenna gain, impedance, and polarization

The documented antenna gain values in the category are 2 dBi, up to 3 dBi, and 15 dBi. The 2 dBi value applies to the indoor 2.4 GHz antennas, the up to 3 dBi value to the indoor dual-band 2.4/5 GHz antenna, and the 15 dBi value to the 5 GHz outdoor base station antenna. All documented antennas have an impedance of 50 ohm.

Why should antenna gain and frequency be checked separately?

The gain values belong to specific antenna designs and frequency bands. The 15 dBi value, for example, applies to the 5 GHz outdoor base station antenna, while the indoor 2.4 GHz antennas are specified with 2 dBi gain. The dual-band 2.4/5 GHz version is specified with gain up to 3 dBi. These values should therefore not be interchanged between antenna types.

WiFi antenna connectors, cabling, and mounting

The antenna connector type should be matched to the receiving WiFi device. The documented range includes MMCX, RPSMA male, and N female connectors. The magnetic-mount antennas include a 1.5 m RG-174 cable, while the outdoor 5 GHz base station antenna uses 4 N female connectors. Mechanical mounting can be direct, magnetic, or mast-mounted using a double clamp.
