DNC100-500 ASSEMBLY MANUAL
Tools required for installation: 7/16” wrench, 1/2”
socket and socket wrench.
NOTE: It is recommended that each screw, rod
and tube connection be assembled using
Penetrox (zinc oxide paste) or equivalent. The
paste or grease lubricates the screw threads and
helps seal the aluminum to aluminum joint from
moisture. This will insure long lasting joints even
in harsh environments as well as aiding in
disassembly should it be required.
It is easiest to install the coax feedline to be used first. Therefore route coax feed cable
through the 1-1/2” x 48” mast extension and mast flange. Tighten the cable connector
securely and then install the mast flange to the hub assembly with cap screws. Next slide
the mast extension tube fully into the mast flange and secure with set screws.
