►
QTY 1 wooden crate, or heavy cardboard container, housing the metal cabinet, which is fully
wired and with all ancillaries, such as 3 dB hybrids, loads, filter, etc. already mounted. This
package has the following approximate dimensions and weight: 1750 x 610 x 940 mm. and
55kg.
QTY 2 heavy cardboard boxes, housing the ETL0470 RF Amplifiers. Each box has a weight of
approximately 35 kg and dimensions: 680 x 610 x 350 mm.
A fourth package, can be optionally included, if the Amplifier has been ordered complete with
Exciter. In this case this package consists of a heavy cardboard box, with the following
approximate dimensions and weight: 610 x 570 x 230 mm. and 27 kg.

Identify, by means of marking stickers on the RF Amplifiers, the
Main Amplifier
(marked N°1) and the
Slave Amplifier
(marked N°2). For the meaning of these denominations, please see this manual,
Section B, “Functional desciption”. Install N°1 in the
upper space
in the cabinet and N°2 in the
lower
space
. These spaces are also marked with corresponding stickers pasted on the inside wall of the
cabinet.
•
Install the Exciter, if supplied, in the space near the bottom of the cabinet.
•
Connect all cables supplied and already wired in the cabinet. In order to simplify this operation,
every cable has stickers at each end. As an additional help, here below is a complete list of all
connections.
QTY 1 “N” to “N” coaxial cable from Exciter, RF OUTPUT socket to low power 3 dB Hybrid.
QTY 2 “N” to “N” coaxial cables from low power 3 dB Hybrid to ETL0470 RF Amplifiers, RF
DRIVE IN sockets.
QTY 2 coaxial cables with 7-16 to 7-16 connectors from ETL0470 RF Amplifiers, RF
OUTPUT sockets, to 3 dB high power hybrid.
QTY 1 “N” to “N” coaxial cable from balancing output of high power 3 dB hybrid, to 50
Ω
high power load.
NOTE: the coaxial cable to the antenna must be connected to the free end of the directional coupler
with a 7-16 connector.
