You may use any combination of omnidirectional (dome) interior antennas needed to obtain op-

SC-222W-TNC provide 360° hemispherical coverage suitable for mostly square areas. The following
example uses two dome antennas to provide full coverage (exterior Yagi antenna also shown):
Keep in mind that floor structures in multistory buildings can cause significant signal loss, which
means that you may need to install interior antennas on more than one floor. Here is an example of
a multistory installation:
