The IRTE parabolic dishes for satellite earth stations are identified by an alphanumeric code with a minimum of 8 and a maximum of 11 characters.
XXXX - XXXXXXX
1234 - 56789AB
1:
P= Prime-focus configuration
C= Cassegrain or Offset Cassegrain configuration
G= Gregorian or Offset Gregorian configuration
F= Offset configuration
2:
A= Fixed full profile
E= Fixed in two halves
U= Trailer mounted
3 and 4:
Reflector diameter in m x 10 (600 mm = 06, 3 m = 30 etc.)
5 and 6:
XX Frequency in GHz receiving
7:
S=
One port only I/O
D=
Two ports I/O
T=
Three ports I/O
Q=
Four ports I/O
*8 and 9 ( * Antennas TX/RX)
XX
Transmission frequency in GHz
L= Linear polarisation
C= Circular polarisation
M= Mixed polarisation
9 or 11 *) (* Antennas TX/RX)
Character destined to codify additional information.
Example:
X= High isolation TX/RX
CU30-11T14L corresponds to a 3 m trailer carried parabolic dish with two receiving ports at 11 GHz and one transmitting port at 14 GHz in linear polarisation..
This new type of coding will progressively replace any other previous denomination. |
