Digital Microwave TV Link EG Series


The microwave link EG series is the ELETEC offer for the distribution of digital signals, designed
for high flexibility along with an extreme ease of use.

EDKLG system is attractive for both individual point-to-point links and complete distribution networks. The transmitter, built in 3HE cabinet, is equipped with a plug-in DVB-S standard QPSK modulator with ASI input and modulation capacity up to 48Mbit/s . The receiver, with two ASI output signals, is built in a 1HE cabinet, integrating a down converter and an IRD. An external optional 1HE demodulator is
required for Audio-Video outputs. The EDKLG series is available in different frequency ranges
from 1.5 to 14.5GHz with different output powers, both in the internal versions or with
external RF heads. In the latter case RF parts are fitted into waterproof tin cases suitable to be
mounted on the rear of parabolic antennas. The external head is connected to the internal
console by a single coaxial cable which passes the RF signal and the power supply. This series
is developed to support only Multi Frequency Network architectures .
For particular difficult connections, a series of external solid-state amplifiers, including highpower
ones, is also available.
