The 301121 is an in building dome antenna. Its gain is weaker than the wall panel antennas, for example the 301135, but its advantage over the 301135 is that it’s an omnidirectional antenna. That means that it covers a radius area of 360 degrees while the wall panel only covers a radius area of 180 degrees.
It is attached to the ceiling with the 901125 mount (included).

Features:

• Built-in ground plane
• Mounting hardware included
