Analog FM Audio/Video Transmitters & Receivers
GMS receivers deliver maximum performance in a miniature and economical package. They are FM-FM radios, providing one broadcast quality video (NTSC or PAL), two FM audio demodulators (4.83-8.5 MHz). All models are fully synthesized with minimum of 16 RF channels. They operate from 300 MHz to 8.6 GHz with typical noise figure of 5 dB. Additional features like built-in monitor, AC power supply are standard on some models.

GMS transmitters deliver maximum performance in a miniature package. They are FM-FM radios, providing one broadcast quality video (NTSC or PAL), and one or two FM audio sub carriers (4.83-8.5 MHz). All models are fully synthesized with minimum of 16 RF channels. They operate from 300 MHz to 8.6 GHz delivering from 10 mW to 10 W of RF output power. GMS transmitters are ideal for sports/ENG broadcasting, POV cameras, and airborne applications.
