XT Series L, S, & C-Band Transmitters
The XT Series transmitters from Cobham Surveillance (GMS Products) incorporate the latest microwave technology in a subminiature package. The XT operates in L, S, or C-Bands with a nominal RF power output of 0.25 W. Broadcast quality video (NTSC or PAL) and two audio subcarriers make this transmitter ideal for hidden camera and point-of-view applications. Where weight is a critical factor, the XT will deliver.
The XT Series is fully synthesized and operates on up to 16 pre-programmed channels. Audio subcarrier inputs may be factory configured for either microphone or line level. All versions require less than 300 mA at 12 VDC.
