Information on product
FULL DESCRIPTION
Antenna
with in-built amplifier. Elements screwed down to the
carrier. Assembling (mounting the reflector with two screws) takes about
one minute. Antenna packed in foil. Aluminum parts, electro-galvanized
steel structural components.
The
LNA-177 preamplifier has been designed for mounting in antenna box,
directly to antenna connectors (300 ohm, balanced). It is ideal device
for amplifying weak signals with low S/N ratios.
The
amplifier works in BIII, IV, and V bands. The metal housing shields the
device and restricts electromagnetic interference. The amplifier is CE
certified.
This
power supply is designed to provide power to preamplifiers/amplifiers
in small terrestrial antenna systems (requiring 12 VDC, with current
consumption up to 100 mA).
The
power supply is protected against accidental shorting. The LED
indicator shows the presence of the output voltage. The included power
supply injector allows power transmission to the preamp/amplifier via
the same coaxial cable which provides RF signals to the receiver.
