MFJ-8704 Micro ATV Transmitter High Performance, SAW stabilized Micro Video Amateur ATV Transmitter This products is only to be used by a licensed radio amateur Specifications: Video Video Input: NTSC or PAL composite video (1 V P-P) SMPTE STANDARD NTSC 625 Line 60 Hz PAL 625 Line 50 Hz RF Center frequency without modulation Output level: Modulation type: Spurious output: VCC Supply Voltage Current draw 433.97 MHz +/- 50Khz +19dBmclean carrier +16.5dBm modulated High level amplitude modulation 2nd harmonic better than 40dB down 9V DC (+/- 300mV) 35 - 40 mA The MFJ-8704 is a high quality, high performance SAW stabilized video transmitter, using surface mount technology. A SAW oscillator is used in the fundamental operating mode to transmit at 433.97 MHz (Cable channel 59). The power output stage uses the latest in MMIC technology. The MFJ-8704's range can vary any where from 1/4 mile to 8 miles depending on the antenna used. A high gain yagi antenna usually provides the best gain. If you plan to build your own antenna, an experimental antenna plan is included; however, commercially available high gain antennas provide the best performance. Use the highest gain antenna possible for both the transmitter and receiver with the shortest possible transmission line. Operation and Setup Video Input The block diagram above shows the how the MFJ-8704 needs to be connected to a video source. Make sure that you have SMPTE standard video at 1 V P-P.
