Note: “Bird-repellent fixtures” may be attached to the antenna cover to prevent<br />
birds from alighting on the cover. If it is more convenient to attach them<br />
before fixing the antenna unit to the mounting location, do step 9 before<br />
fixing the antenna unit.<br />
NOTICE<br />
Fasten the antenna to the mounting<br />
location lastly if it is more convenient<br />
to connect the antenna cable before<br />
mounting the antenna unit.<br />
1. Prepare a mounting platform (wood, steel or aluminum) in accordance with<br />
the illustration shown below. If corrosive material is used, take necessary<br />
anti-corrosion measures.<br />
Note: When drilling holes in the platform, be sure they are parallel with the<br />
fore-and-aft line.<br />
2. Fasten the antenna unit to the platform with four sets of M10 hex. bolts,<br />
spring washers and flat washers, orienting it as shown below. (The bow mark<br />
(�) on the antenna should face the bow.) The torque for the hex. bolts<br />
should be between 19.6-24.5 Nm.<br />
NOTICE<br />
Do not open the antenna.<br />
This installation does not require removal<br />
of the antenna cover.<br />
