DON'T waste your money on a poor transmitter!!!

Wavemach Communication's new 200W-video-tx is a heavy duty 200 watt TV transmitter that will get your signal out! .

Simply connect your audio source, video signal and matched antenna and your station is live! The frequency range of the modulator is good for 45 MHz to 870 MHz and is programmable in 250 KHz steps. The audio carrier can be set at 4.5 Mhz, 5.5 Mhz, 6 MHz and 6.5 MHz so the unit is compatible with NTSC, PAL, SECAM and other standards. Sideband energy is around 30 db down at a 150 watt level and slowly increases when the power is increased up to 200 watts. At lower output power levels the sideband signal energy decreases to well below -30 db. The output amplifier board is capable of a lot more output power but as the signal is increased the picture quality will degrade. The output board uses two 300 watt transistors for excellent reliability.

The video modulator is micro processor controlled and allows you to adjust the audio level, video level, A/V level, and RF output by using the soft touch buttons. The output of this modulator is connected to the high gain 55 db gain 200 watt amplifier. The power output of the video amplifier is easy to vary by the modulators variable RF level.

The amplifier is a high gain wideband design and never requires tuning for channel 2 to channel 6. The 2 units are both standard 19" wide.
