AOR LA800, Instruction Manual

Page: 4 / 16

1. Introduction
Thank you for purchasing the LA800 SUPER LOOP ANTENNA.
LA800 is AOR’s new and first OUTDOOR and WATERPROOF shielded loop antenna for
reception between 10kHz and 500MHz!
To get the best possible results from your LA800, we recommend that you read this manual
and familiarize yourself with the antenna.
First, a word of caution: LA800 is a RECEIVE ONLY antenna. Do not transmit with it or its
circuitry will be severely damaged, maybe even beyond repair.
In recent years, the increase in man-made local noise (typical city noise) poses a problem
for the reception of distant signals in the long wave, medium wave and shortwave bands.
LA800 is our latest product based on the technology we developed since the original LA320
indoor loop antenna. In addition to its exceptional directivity in order to minimize the effects
of local noise, the revolutionary LA800 offers, with its REMOTE TUNING SYSTEM , the
perfect solution to keep the antenna away from noise sources by setting it up in quiet areas!
While the control (tuning) box stays at hand’s reach, the WATERPROOF loop element can
be permanently setup outdoors.
10kHz to 500MHz, 6 position band switch to peak only on the wanted signal. Built-in low
noise amplifier for exceptional 20dB gain. Loop element diameter of 80cm for maximum
reception performance.
Remote tuning – The supplied 10m control and coaxial cables, separating the antenna
from the control box, allow to conveniently operate band switching and fine tuning controls
placed on the control box..
A relay system is used for band switching, providing excellent isolation characteristics.
The relay is efficiently placed inside the loop element, while you can operate it through the
control box via the control cable.
Electronic tuning from 150kHz
〜
30MHz allows very sharp tuning to the desired
frequency. Shift the aligning point slightly to attenuate unwanted signals while amplifying
the wanted signal.
Waterproof – The loop element’s electronic circuitry is housed in a ABS plastic box, water
and dust proof to IP65 standard.
