NT Series L, S, & C-Band Transmitters
The NT Series transmitters from Cobham Surveillance (GMS Products) incorporate the latest microwave technology in a subminiature package. The NT operates in L, S, or C-Bands with a nominal RF power output of 10 mW. Broadcast quality video (NTSC or PAL) and one audio subcarriers make this transmitter ideal for hidden camera and point-of-view applications. Where weight and size is a critical factor, the NT will deliver.
The NT Series is fully synthesized single channel Transmitter. Audio subcarrier input may be factory configured for either microphone or line level. All versions require less than 150 mA at 12 VDC.
