Installation
Your AT-7000 tuner is intended for indoor use only; it is not water resistant. If you use it
outdoors (Field Day, for example) you must protect it from rain. The AT-7000 is designed for use
with coax-fed antennas. If you wish to use it with longwires or antennas fed with a balanced
transmission line (e.g., ladder line), an external balun is required; either the LDG RBA-4:1 or
RBA-1:1 is ideal, depending on the antenna and transmission line used.
Always turn your radio off before plugging or unplugging anything. Your radio may be damaged
if you connect or disconnect a cable with the unit powered up.
Connect the HF antenna jack on your IC-7000 to the
TX
jack on the back of your AT-7000 tuner
using the provided coax jumper cable. Attach your antenna lead-in coax to the
Ant
jack on the
back of your AT-7000 tuner.
Connect the tuner’s
RADIO
jack to the
TUNER
jack on the radio using the provided data cable.
The AT-7000 can also be used with any Icom radio that is compatible with the AH-3 or AH-4
antennas. Please check your radio’s instruction manual for compatibility. This includes, but is not
limited to:
-
IC-7000
-
IC-718
- IC-706 (all variations)
- IC-746
- IC-703Plus
- IC-756 (all variations)
Grounding your tuner will enhance its performance and safety. LDG recommends that you
connect your tuner to a suitable ground; a dedicated ground rod connected to buried radials is
preferred, but a single ground rod or a cold water pipe can provide a serviceable ground. LDG
strongly recommends that you use a properly installed, high quality lightning arrestor on each
antenna cable.
