I put this together from Frequency charts that Demetri Vafeas had sent me
many years ago.

Section 1.5 Avlis "The Voice Of Hellas".
The 5th 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 Marconi short wave transmitters and a veritable forest of
antennas covering 1,100 acres, arranged in three lines to 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.
1.5.a Antennas.
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 180 degrees 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 M.U.F. allows it.
For transmissions to neighboring countries like Cyprus, Turkey, the
Balkans and the countries of the Middle East, there are two rotatable log
periodic antennas with a high angle of vertical radiation (45 degrees) and
a wide angle of 32 degrees in the horizontal plane.
1 - The remotely controlled switching center allows each of the two
transmitters to be connected to any one of the 23 antennas.
2 - Electromechanical protection circuits ensure that a transmitter can
only be connected to an antenna that is tuned to the same frequency.
3 - 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 now familiar signature tune of a shepherd playing his
flute with the tinkling of sheep-bells in the background, recorded in
1936, followed by the Greek National Anthem.
The special programs of news and features originate in the broadcasting
headquarters in Athens and go on the air throughout the 24 hours of the
day in Greek, English and many foreign languages. Reports of reception are
welcome and should be addressed to K.E.B.A., Avlis, Greece.
(The Greek initials stand for short wave transmitting center.)
Avlis has three series of curtains, some of which have been used in the
antipodal mode:
HR1 (46 / 226 and 80 / 260 degrees),
HR2 (105 / 285 and 120 / 300 degrees),
HR3 (2 / 182, 46 / 226, 105 / 285, and 143 / 323 degrees).
