France closes its shortwave relay facilities in French Guyana



Ian Baxter of the shortwave transmitter group points out two TV reportages on the closure of the French shortwave broadcast transmitter site near Montsinery, French Guyana. The site was opened in 1985 in order to strengthen reception of Radio France Internationale in both North & South America as well as West & Central Africa.

These massive shortwave antenna  towers in Central France worked well for North Africa, but signals into Latin America were not competitive. Hence the decision to build a site in the Northern part of South America.



Later the towers in Issoudon were replaced with a new more compact design. These antennas are rotatable.
Signals from a transmitting centre at Issoudon in central France could not compete with signals from other broadcasters like VOA, Radio Netherlands, BBC and Deutsche Welle who all had relay transmission facilities somewhere in the Americas. The site in French Guyana was upgraded in the 1990's with a new set of combined high power transmitters and rotatable antennas. These take up far less space. Whereas the ALLISS antenna system usually has the transmitters in the base of each antenna, it seems the antennas installed in French Guyana were just connected to the existing transmitters. It didn't make sense to get rid of the existing transmitters.

From local news reports, it seems that 6 employees at the site will supervise the station's dismantling operation over the next 9 months.
