Microwave Transmission Considerations for the MDC
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 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
