 Of the two popular approaches to wireless camera operation, DBS employs the pole-mounted directional transmitter method for several reasons.  Camera-mounted systems typically use omnidirectional antennas which, in an urban environment, can produce a number of unwanted side-effects.

An omnidirectional antenna transmits in all directions so that the receiver not only receives the direct signal from the camera-mounted transmitter but reflections from buildings, moving vehicles or interior walls.  These problems are worsened with the degree of camera movement.  This multipath results in signal break-up, fading, ghosting as well as unstable color.

By using a battery-operated broadcast-quality transmitter with a directional antenna atop a pole all of these problems are reduced or eliminated.  Walking alongside the cameraman and connected via a short cable, the microwave technician maintains directional control of the transmitter.  Other advantages are that the transmitter is elevated above obstructions, a higher-power transmitter can be used, and the combination of higher power and the directional antennas on both the transmitter and receiver  greatly increases the possible distance to the receiver to several blocks.

Based on the needs of the event, DBS can supplement these capabilities with wireless IFB, two-way wireless intercom and other wireless communications.  The wireless intercom can also be interfaced with RTS or ClearCom intercom systems and the microwave technician helps facilitate communications for the busy cameraman and talent.  And any user-supplied camera can be used.
