1/2GHz FM Modulator Picture & Stereo Sound

In rural areas or over very long ranges the distribution of TV programs by cable is a very expensive solution.

Link Modulator

As an economical alternative we can offer the distribution by microwave links in the 1-2GHz range under the condition of optical sight between transmitter and receiver.
This transmitter delivers a signal which is identical to a standard satellite signal.

This means that standard satellite receivers could be used for reception which is a very low cost solution.
This system can supply an unlimited number of receivers within the transmitter`s range.
When using 12dB gain antennas for transmitting and receiving the distribution range is about 10 kilometers.

We can also offer an accu-powered version (12V/1.3Ah=8hours) for portable or solar-powered applications.

For high frequency accuracy the transmitter is phase-locked (PLL).
It is also possible to feed an additional power amplifier (PA) by the coax cable to the antenna (I max. 300mA)
