Medium Wave Transmitter
In 1987 a switchable directional antenna consisting of five ground-fed guyed masts was built nearby for the 1467 kHz medium wave frequency, which was previously transmitted from a transmitter at La Madonne. This antenna allows a switchable directional radiation in the following directions:
| Destination | Azimuth |
|---|---|
| Scandinavia | 25° |
| Eastern Europe | 85° |
| Italy and Greece | 150° |
| Spain, Portugal, Northern Africa | 241° |
| UK | 325° |
Changing the signal direction takes only 5 seconds. There are no matching network buildings at the bottom of the masts used for medium wave transmission – the devices for tuning the masts to the transmission line are placed in the open air, similar to those in the longwave antenna system.
The medium wave Roumoules transmitter has an output power of 1,000 kilowatts (1,300 hp). It is also used for transmitting the religious programmes of Trans World Radio. In comparison to the longwave transmitter, which can be received well both at day and night in Southern France, Northern Italy, Switzerland and Southern Germany, this transmitter cannot be normally received well more than 100 kilometres (60 mi) from Roumoules. However at night its transmissions may have at least the same range as those of the longwave system due to its skywave propagation.

Famous quotes containing the words medium and/or wave:
“The role of the writer is not simply to arrange Being according to his own lights; he must also serve as a medium to Being and remain open to its often unfathomable dictates. This is the only way the work can transcend its creator and radiate its meaning further than the author himself can see or perceive.”
—Václav Havel (b. 1936)
“The history of any nation follows an undulatory course. In the trough of the wave we find more or less complete anarchy; but the crest is not more or less complete Utopia, but only, at best, a tolerably humane, partially free and fairly just society that invariably carries within itself the seeds of its own decadence.”
—Aldous Huxley (1894–1963)
