it is absolutely necessary in order to save time. A good rule of thumb is to assume that
the MDC has an antenna pattern that is about 100 degrees wide. In other words, it is
the MDC has an antenna pattern that is about 100 degrees wide. In other words, it is
necessary to point the MDC in at least 4 different directions around the room to cover the
perimeter. Also, the MDC should be pointed up and possibly moved around the room to
cover the ceiling, and down to cover the floor. Furthermore, if you expect a very
sophisticated threat, it is recommended to point the MDC into ducting, above ceiling tiles,
and in any enclosed spaces in which it would be possible to place a transmitter with a high
gain antenna. It is highly recommended that the “Show All” mode of operation for the
MDC-2100 be utilized (MDCA-all and MDCB-all if using OSCOR 5.0). When a signal is
detected, the user can then manually select the different antenna bands and filters to
further investigate the signal. Or, the user can simply go to the analyze mode and allow
the MDC to determine the operational frequency of the transmitter. Also, it is not
recommended to use the MDC with the OSCOR automatic mode unless the MDC
directional characteristics are taken into consideration. If running the OSCOR and MDC
in the automatic mode, take care to enable the appropriate MDC spans. To maximize
usage of the MDC, include MDC 3-21GHz Filter A and MDC 3-21GHz Filter B in your
span list (For OSCOR 4.0 users, set span to All Bands A&B).
