Outdoor Installation

Pre-installation Precautions

(a) If installing the Antenna Tuner on a pole, secure the pole to a cross beam plate for reinforcement,
and if necessary, brace with a stay. Also remember to take into consideration the required strength
and ability to withstand vibrations and corrosion when making the pole and setting the angle.
(b) If installing the Antenna Tuner on the ship wall, attach the tuner mounting bracket to a beam for
reinforcement, and if necessary, provide further support. Take into consideration the required
strength and ability to withstand vibrations and corrosion when making the mounting brackets.
(c) When installing the Antenna Tuner in protective sheltering, ensure that there is adequate space for
future maintenance. (Use either removable or door type protective sheltering to allow access for
maintenance)
(d) Ensure that the bolts and washers to be used for the Antenna Tuner and Junction Box installation are
corrosion resistant.

Installation Precautions

(a) To ensure water resistance, install the Antenna Tuner so that the antenna terminal (insulator) side is
up.
(b) To ensure water resistance, do not cut, remove, bend or attach with cables the rubber ventilation
tube to lower part of the Antenna Tuner. Furthermore, to ensure proper ventilation do not allow the
end of the tube to touch the floor

Post-installation Precautions

(a) Be sure to fully coat the 6ZPKD0084 Grounding Terminals extending from the Antenna Tuner and
the ship wall with paint to prevent those parts from corrosion. It is recommended to reapply this
coating once a year.
(b) After connecting cables between the Antenna and Junction Box, be sure to plug the remaining open
space inside the lead-in cable tunnel with silicon glue.
