Choose the antenna based on the install location and designed area of coverage. The datasheet includes a list of certified antennas. These are listed for sale on the product page.
3rd party antennas may be used but it is the responsibility of the end customer/partner to ensure operation is within regulatory compliance.
All dual-band 2×2:2 outdoor APs (such as the MR74 and MR76) have two sets of mount points: the top two are for the 2.4GHz radio, the bottom two are for the 5GHz radio.
(The dual-band 4×4:4 outdoor APs (such as the MR84 and MR86) have both the 2.4 GHz and 5 GHz radios diplexed onto each antenna port, thus dual-band antennas should be paired with those APs.)
The model of the antenna denotes whether it should be connected to the 2.4GHz or 5GHz mount points, or if it supports both. Supported bands are also color-coded on the antenna’s base, where green denotes 2.4GHz support, blue denotes 5GHz support, and both indicates that the antenna is dual-band.
Sector/patch antennas have two connectors. Both of these connectors must be attached to the same radio, a single sector/patch antenna should not be attached to both the top and bottom of the access point
Connecting dual band antenna to single band port will only grant that band. Likewise if you connected the dual band omni antennas to all ports, you would only get 2.4 on top and 5 on the bottom.
Therefore the best choices for the MR74 are:
- Omnidirectional MA-ANT-20 top & bottom
- 2.4GHz Sector Antenna top MA-ANT-23
- 5GHz Sector Antenna bottom MA-ANT-21
The MR74 features single band antenna ports thus single band antennas should be paired with the AP.
Meraki offers a number of antenna options for the MR74 access point. Below is a highlight of the different antenna types and their applications. It is always best practice to consult with a Cisco SE or Partner in to select the best antenna for the unique design.
Omni directional antennas are best for pole mounts applications and for mesh networks. Use omni directional antennas when designing to cover 360 degrees around the Access Point.
Sector antennas are ideal for building mounts as they target the signal away from the interior spaces of the building and focus the energy to the larger outdoor space. This antenna is ideal for exterior building use but may also be used for some mesh network designs.
Patch antennas are ideal for Access points mounted on a high ceiling and is intended to cover a large space. This antenna is ideal for warehouses.
Stadium Patch Antenna
A stadium patch antenna is ideal for a high density AP deign with expected high user per sqft. Examples of this are in stadiums where 1 AP is designed to cover a section and a event center where there is high user per sqft.
