The feed wire bolt assembly can face either forward or to the rear, depending on how you will
connect the feedline. If you are using the optional DXE-8X16-RT pigtail to feed the vertical, orient
the feed wire bolt to the rear, facing the backing plate as shown in Figure 6.

Base Section to Mounting Pipe

Locate the two V-Saddle Clamps. Assemble them on the mounting plate as shown in Figure 4. We
have included an aluminum grounding kit to facilitate making the ground connection to the vertical.
(Use is optional unless the DXE-8X16-RT feedline pigtail is used). The kit contains a short
aluminum strap, large and small star washers along with a 1/2" x 10-24 bolt, and nut. To install,
place the larger star washer from the kit on the right side U-bolt of the lower V-Saddle clamp so it is
against the mounting plate. Put the aluminum strap on the U-bolt, then the flat and lock washer and
nut. Figure 5 shows the pigtail and aluminum ground strap mounting. To connect the feedline to the
pigtail, you will need a DXE-363-SST bulkhead adapter.
If you are not going to use the grounding bracket, the flat washers with the clamps should go against
the aluminum mounting plate, then the lock washers and nuts.
The mounting pipe installed in the ground should not extend above the insulated channel. Use
Never-Seez® on all stainless threads to prevent galling which can give a false feeling of being tight.
However, with these clamps it is not necessary to use excessive torque to get an excellent
mechanical connection. Once the lock washer has been flattened out, the clamp is tight enough. Any
clamp should be tightened evenly from side-to-side with an equal amount of thread visible above
the nut.
