Thanks to its directionality, it is also ideal for minimizing the effects of unwanted interfering local terrestrial
signal and noise.
The loop element features a 5 positions band switch and a High-Q poly-variable capacitor to tune and peak
the wanted frequency, while achieving maximum rejection of unwanted out of band signals ? valuable
additional selectivity for your receiver f s fr on -end stages.
Using the LA380 active loop aerial
lead between the LA380 and your receiver f s ae ri a l i npu t. If you r r ece i ve r i s fitt ed w it h a connec t o r o t he r t han
BNC, an appropriate adaptor must be used.
3) Insert the receiving loop element into the top panel BNC socket of the LA380 cabinet.
4) Push the red front panel power switch, the green LED will illuminate to confirm that power is connected to
the control unit.
5) Switch on the receiver and tune to the desired frequency. Select the correct frequency range with the
band switch on the loop element. There are 5 positions to choose from:
Frequency
Comments
40 kHz
Specifically for Japan time signal
60 kHz
Specifically for US, UK & Japan time signal.
3-10 MHz
Shortwave bands 100 to 30 Meters.
9-40 MHz
Shortwave bands 33 to 7 Meters.
Others
60 kHz to 3 MHz
40 MHz to 500 MHz.
1) Connect the power supply to the rear
panel DC input socket, the LA380 requires
12V DC at 50mA (9-15V DC). A 9V
regulator is built into the LA380 control unit.
To minimize noise, keep the power supply
as far away from the LA380 as practical. To
minimize electrical interference from the
power supply, for the receiving range
between 10kHz and 1.6MHz, you may wish
to consider use of a (non supplied) low
noise regulated power supply.
2) Connect the supplied BNC-BNC coaxial
