3.3 - Interior Antennas
You may use any combination of omnidirectional (dome) and/or directional (at panel) interior anten-
nas needed to obtain optimal signal strength throughout the building or installation area. Dome
antennas such as the SC-222W, SC-223 and SC-224 provide 360-degree hemispherical coverage
suitable for mostly square areas while at panel antennas such as the SC-248W provide a focused
zone of coverage suitable for long narrow areas. The following example uses two dome antennas and
one panel antenna to provide full coverage (exterior Yagi antenna also shown):
Keep in mind that oor structures in multistory buildings can cause signicant signal loss, which
means that you may need to install interior antennas on more than one oor. Here is an example of
a multistory installation:
