The MT series transmitters from Cobham Surveillance (GMS Products) deliver maximum performance in a miniature package. The MT operates in L, S, or C-Bands with a nominal RF power selectable between 0.25 W and 2 W. Broadcast quality video (NTSC or PAL) and two audio subcarriers make this transmitter ideal for sports broadcasting, point-of-view cameras, and airborne applications.
A switch to chose either microphone (position 1) or line input (position 2) is located next to the power select switch; audios must both be either on line or both on microphone input.
