Page 6: Warning
WARNING! INSTALLATION OF ANY ANTENNA NEAR POWER LINES IS DANGEROUS Warning: Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, because they may cause serious injury or death. -
Page 7: Mounting Pipe
Using enough staples will ensure the wires will not be snagged by mowers, people, or animals. Grass will quickly overgrow the radials and it will be virtually impossible to see them. An article describing this process is available the DX Engineering website www.dxengineering.com in the Tech Info section. -
Page 8: Assembly
Assembly The DXE-40/30 Meter Vertical Antenna shipping box contains the vertical tubing sections, an insulated U-channel, two 3/8" U-Bolts, saddles with hardware, a backing plate, a Tilt Base, stainless steel element clamps, a black vinyl cap, and stainless steel hardware. Carefully un-pack the antenna and separate the various parts. -

When fully assembled and you are standing in front of the antenna and can read the DX Engineering logo on the tilt plate, the antenna tilts to the right. Refer to Figure 9 or Figure 15 for a picture showing the front of the antenna. Tighten the clamps evenly so the length of the exposed threads is approximately equal. -
Page 11: Vertical Base Section
Vertical Base Section ® The base section is made up of an Extren insulated mounting channel with hardware, a mounting plate, two 3/8" U-Bolt assemblies and the base antenna element sections. Using Figure 4, attach the aluminum backing plate to the back of the insulated channel. The base hardware kit contains four 2"... - Page 12 Install the lower sections to the insulated channel using the 2 - 3/8" x 2" U-Bolts, 2 saddle clamps, 4 flat washers, 4 split washers, and 4 nuts as shown in Figure 7. The base section tube should extend 1-1/4" beyond the bottom of the U-bolt clamp. When tightening, observe the split washers. When they fully seat (flatten out), the clamp is tight enough.

Base Section to Tilt Base Place the Lower Base Section into the holes of the Tilt Base and loosely install the Tilt Base mounting hardware shown in Figure 8. Figure - 8 - 12 -... - Page 14 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. 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.

Page 19: Mating The Vertical Sections To The Tilt Base
Mating the Vertical Sections to the Tilt Base CAUTION: Attempting final assembly without proper precaution can be dangerous. You should have someone help you steady the vertical antenna sections during mating with the base section. Note: A pair of sawhorses or ladders should be used to support the vertical sections during assembly with the Tilt Base and whenever the vertical is tilted down. -
