Cisco Meraki Indoor Dual-band Omni Antenna, 5-port

The Panel Omni antenna is ideal for low ceiling aesthetic conscious
installations where wall penetration or extended reach are important.
Some example uses are low-density deployments like schools and
hotels to provide basic low-performance connectivity. These types of
best-effort deployments usually have APs installed in the hallway to
cover adjacent rooms.
