Greece's Elliniki Radiophonia antennas and service areas

VOG antennas (
Compiled By John Babbis, Silver Spring, MD, USA

The Fifth Program of the Greek Broadcasting Service (Elliniki Radiophonia) is transmitted from the short-wave transmitting center at Avlis, about 70 kilometers north of Athens. The station was put into service in 1972, and has two 100-kW H.F. Marconi B-6123 Broadcast Transmitters and one 250-kW
Continental 419 F-2 Broadcast Transmitter (working at 70 kW. with an effective radiated power of 170 kW).

Antennas covering 1,100 acres, arranged in three lines cover the desired directions. The pylons supporting the 6 MHz arrays are truly impressive at 328 feet. Each line has eight separate antennas for the 6, 7, 9, 11, 15, 17, and 21 MHz Broadcasting bands. Each antenna consists of two curtains
with a total of 8 horizontal dipoles. The dipoles are all fed by open wire feeders which can be remotely switched to enable radiation in two directions 180deg apart. There are also three curtains for the 11 meter band (26 MHz) which may be put into service during Sunspot Cycle 22 if the
Maximum Usable Frequency allows it.

For transmissions to neighboring countries like Cyprus, Turkey, the Balkans, and the Middle East, there are two rotatable-periodic antennas with a high-angle of vertical radiation (45 deg) and a wide angle of 32deg in the horizontal plane. The remotely-controlled switching center allows each of the two 100 kW Marconi transmitters to be connected to any one of the 23 antennas. Electro-mechanical protection circuits ensure that a transmitter can only be connected to an antenna that is tuned to the
same frequency.

The Continental transmitter is connected to a separate antenna.

The change of antennas and transmitting frequencies is made during the ten minute interval between programs, which always begin on the hour, preceded by the familiar signature tune of a shepherd playing the flute with the tinkling of sheep bells in the background followed by the Greek National

Avlis has 3 series of curtains, some of which have been used in the
antipodal mode:

HR1: 046 / 226 deg HR2: 105 / 285 deg
080 / 260 deg 120 / 300 deg

HR3: 002 / 182 deg 105 / 285 deg
046 / 226 deg 143 / 323 deg

Also, 2 log-periodic rotatable (000 deg ... to 360 deg) which have been used for the azimuths of 002 deg, 008 deg, 052 deg, 100 deg, 292 deg, and 306 deg.

GREECE - ERT update.
So ... here's a quick update on the Greek public broadcaster.

ERT's website has gone online, has just corporate information. However, as of 31 May evening the broadcasting is still apparently done as NERIT. is also online at the moment and streaming ET3 from Thessaloniki(which managed to stay on air online(and I think on some
remote satellite) the whole affair). Of course, as we approach June, symbolically they might as well choose 11 June - the day the shutdown decision came two years ago. This is also the date I've seen going around in Greek sources, including this Greek posting from Friday
