Figure 16
shows the completed
DXE-TB-7P
assembly mounted to the customer supplied mounting
pipe. The standard 1-1/2" galvanized water pipe (with its 1.9" OD) is just fine for this application
and can usually be found at your local home building supply store) using two
DXE-SSVC-2P
Stainless Steel V-Clamps.
DXE-TB-8P with Comtek 20 Meter
Verticals:
The Comtek adapter plate is used to allow the Comtek 20 Meter Vertical antenna to easily attach to
the Tilt Base. Except for the U-Bolts and U-Bolt hardware, all the other parts are the same as the
TB-7P kit.
The installation instructions are the same as the
DXE-TB-7P
with only a few differences. The
custom short thread 1-1/2” U-Bolts have 1/4-20 threads, sized to fit the
COM-20VA
antenna. Use
the mounting holes on the supplied adapter plate that fit the 1-1/2” U-Bolts.
The rest of the assembly is the same as the
DXE-TB-7P
.
Using the Tilt Base
Using a wrench or nut driver, securely tighten the two Nyloc Nuts at the bottom of the Tilt Base.
Then loosen them one-half turn each. Loosen the top two Nyloc nuts and flange nuts. This will
allow proper movement of the Tilt Base while raising or lowering the antenna. It is not necessary to
tighten these nuts more securely unless further tilt operation is no longer required. The bottom
Nyloc Nuts should not be loosened more than one-half turn at any time. The upper Nyloc nuts are
used to secure the tightened flange nuts from becoming loose if the wind vibrates your antenna
assembly.
DANGER
: Make sure you have not inadvertently located the
antenna underneath power lines.
Residential power lines are often less than 40' high.
Contact With Any Power or Utility Lines Can Be Lethal !
Test the tilt function to ensure proper clearances. Standing in front of the Tilt Base, lift the antenna
base section, slide it to the right, and let it down slightly until the lower outside bolt is resting in the
pivot point. Then slowly tilt as shown in
Figure 17
. Make sure when you are tilting the antenna to
lift, slide to the right
, and
then
tilt. Be careful to keep the pivot bolt resting in the pivot point.
Reverse the process when raising the antenna.
It is important to note that the lower, outside bolt becomes the pivot point while raising or lowering
the antenna. This pivot bolt
MUST
be retained in the pivot point. It seems natural to
push
the
antenna toward the Tilt Base while raising.
Push up
while raising, but not toward the base since this
could cause the pivot bolt to lift out of the slot and allow the mechanism to bind up and bend the
lower bolts.
