Antenna Gains per AP Model

Mist AP Antennas

The tables below show the maximum gain for which the Juniper Mist AP, or the AP plus an external antenna, is certified. Note, though, that the maximum allowable gain will vary according to the regulatory domain in which the AP is operating. As such, when configuring the gain settings for a given AP, you need to be sure not to exceed the maximum allowed by local regulations.

Take the case of an AP43E with an external directional antenna, for example. The AP supports a gain of up to 8 dBi on the 2.4 GHz radio band, and up to 10 dBi on the 5 GHz radio band. This level of gain will exceed the maximum allowed for some regulatory domains. Thus, although the AP hardware supports it, and you can configure a 10 dBi gain in the software, a setting of 10 dBi would be mistake if your local regulations do not allow it.

Table 1: External Antenna Gains

Model	Antenna Type	2.4 GHz	5 GHz	6 GHz
AP34E	Omni Directional	4dB 8dB	6dB 10dB	~
AP41E	Directional	8dB	8dB	~
AP43E	Directional	8dB	10dB	~
AP45E	Omni Directional	4dB 8dB	6dB 10dB	6dB 10dB
AP61E	Directional	8dB	8dB	~
AP63E	Directional	8dB	10dB	~

When configuring a gain of 6 dBi or higher for an external antenna, we recommend that you make the setting in the RF Template, a device profile, or at the level of the individual AP. An example configuration from the Radio Settings page (site-level) is shown in Figure 1. Note that the External Antenna Gain option does not appear for internal APs.
