Page 2: Overhead Power Line Safety
Introduction The DX Engineering DXE-MBV-2 is a custom made fast taper 49 feet high multi-band vertical antenna system. There are no traps, coils or linear loading elements. Designed with 6063 corrosion- resistant aluminum tubing and stainless steel hardware, this antenna is very durable and attractive. -

Page 4: Installation
Additional Material Needed but not Supplied: • Antenna Mounting - Steel mounting pipe, 2.0″ OD maximum, 0.25″ wall thickness, 4 feet long. 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. •... -
Page 5: Mounting Pipe
An article describing this process is available on the DX Engineering website in the Tech Info section. Radials can also be buried just under the surface by using a power edger to make a slit in the soil. Mounting Pipe Use a customer supplied thick-walled galvanized steel mounting pipe at least 4 feet long. - Page 6 Note: JTL-12555 Jet-Lube™ SS-30 Anti-Oxidant should be used between all antenna element sections. Jet-Lube™ SS-30 is an electrical joint compound to affect a substantial electrical connection between metal parts such as telescoping aluminum tubing or other antenna pieces. It ensures high conductivity at all voltage levels by displacing moisture and preventing corrosion or oxidation.
- Page 7 Attaching the included Ground Radial Wires to the Radial Plate Using the 20 sets of supplied 1/4" stainless steel hardware (Bolt, Star Washer, Flat Washer, Split Washer, Nut) connect the included DXE-RADW-32RT Pre-Assembled Radial Wire Kit ground radial wires to the DXE-RADP-3 Radial Plate as shown in Figure 2. Additional hardware kits are available (DXE-RADP-1HWK) that contain 20 sets of Radial Plate Hardware are available in case you loose some hardware, or decide to add more radial wires.

Page 8: Tilt Base To Mounting Pipe
Tilt Base to Mounting Pipe Install the Tilt Base to the 2" OD mounting pipe using the two DXE-SSVC-2P V-Bolt Saddle Clamps allowing approximately 4-1/2" clearance between the bottom of the tilt base plate, to the top of the DXE-RADP-3 Radial Plate as shown in Figure 3. Make sure the Tilt Base and DXE-RADP-3 Radial Plate are oriented correctly for the direction you wish to tilt the antenna. -
Page 9: Vertical Base Section
Vertical Base Section ® The base section is made up of an EXTREN insulated mounting channel, a mounting plate with hardware, two 2" x 3/8" U-Bolt assemblies and the base antenna section which is 2" OD thick wall, 36" long with a hole drilled at bottom end for the feedpoint hardware. Refer to Figure 4 and attach the aluminum backing plate to the back of the insulated channel. - Page 10 Install the lower antenna element section to the insulated channel using the two 2" x 3/8" U-Bolts, two saddle clamps, four 3/8" flat washers, four 3/8" split washers and four 3/8" hex nuts as shown in Figure 6. The base section tube should extend 1-3/4" beyond the bottom of the U-bolt clamp. The feedpoint hardware should be coming out on the left side as you look at the lower section as shown in Figure 6.

Page 11: Base Section To Tilt Base
Base Section to Tilt Base Place the Lower Base Section into the holes of the mounted Tilt Base and loosely install the Tilt Base mounting hardware shown in Figure 7. Leave the flange nuts and Nyloc nuts slightly loose. Figure - 7 Using a wrench or nut driver, securely tighten the two Nyloc nuts at the bottom of the patented Tilt Base. -
Page 12: Assembling The Vertical Sections
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 8. Make sure when you are tilting the antenna to lift, slide to the right, and then tilt. - Page 13 Deburring is a finishing method used in manufacturing. Our aluminum tubing is machine cut on both ends and machine slit on one end. Although DX Engineering manufactured aluminum tubing is deburred, you should further assure that there are no ragged edges or protrusions.
- Page 14 Each tubing section is inserted 4" into the next larger tube. Assembly is easier if the overlaps in the tubing sections are pre-marked. A dark color felt-tip marker works well. Measure and mark 4" from the end of each tube without the slit using a marker so it will be clearly visible. Locate the 15 Element Clamps.

Page 16: Mating The Vertical Sections To The Tilt Base
Mating the Vertical Sections to the Tilt Base CAUTION: Attempting final assembly without proper precautions can be dangerous. You should have someone help you steady the vertical antenna sections during mating with the base section. Do not attempt to raise or lower the antenna if there are strong wind gusts, local thunder (lightning) or if there are nearby electrical wires that may come in contact with the antenna. -
Page 17: Feedline Connection
Note: As you raise the antenna to the vertical position, it’s important to also maintain the parallel alignment between the antenna mounting channel and the Tilt Base backing plate to minimize binding. Make sure the lower tilt- base bolts are never excessively loose before raising or lowering. - Page 18 Your coaxial cable from the radio connects direct to the DXE-1023 N-Type bulkhead connector installed on the DXE-RADP-3 Radial Plate as shown in Figure 13. Weatherproofing this coaxial ® ™ connection using TES-06132 - Scotch Super 33+ and TES-2155 - 3M Temflex 2155 Rubber Splicing Tape is highly recommended.
