Introduction

The DXE-AOK-DCF Direct Coax Feed assembly by DX Engineering for the Hustler® BTV series
antennas allows direct connection from a coaxial cable with a PL-259 connector.

Features

 Laser Cut Stainless Steel Bracket and Stainless Steel Hardware
 High Quality SO-239, PTFE insulation, 14 gage copper insulated wire link with weather sealed

connections pre-installed

 Provides a positive coaxial connection to the antenna system, rated at 1500+ watts
 Can be positioned in three configurations
 Custom Manufactured for the Hustler® BTV series antennas
 Allows easy removal of coaxial cable for maintenance

Parts Included

1 - SO-239 and insulated wire link with star washer, nut, and weather sealed connections installed

1 - Laser Cut Stainless Steel Bracket

5 - #10 Star Washers

1 - 1/4" x 0.5 OD Flat Washer

3 - 10-24 x 1" Hex Head Bolts

1 - 1/4" Star Washer

1 - 1/4" Aluminum Spacer

1 - 1/4-20 X 1" Phillips Head Screw

3 - 10-24 Nuts

1 - 1/4" Split Washer

Tools Required

3/8" and 5/16" Wrenches or Nut Drivers, 3/4" Wrench, # 3 Phillips Head Screw Driver

Installation

Depending on your antenna configuration, you may install the DXE-AOK-DCF in one of three ways
(Figure 1). The direction of the SO-239 will depend on your particular installation set up. Ensure the
direction chosen allows the coaxial cable to be properly connected. When the patented DXE-TB-3P Tilt

Base for Hustler® BTV Antennas is being used, allow clearance for the coaxial cable when tilting.

Upright Position Tilted Position
Three Mounting Possibilities Suggested orientation using Tilt Plate & Radial Plate

Radial Plate, Tilt Base & Coaxial Cable are optional

Figure 1

If your BTV is already installed, you may want to remove the antenna from the base to allow easy access to
the bottom of the antenna bracket where the feedline is connected. Remove and discard the existing coaxial
connection and the original slotted head screw at the feedpoint of the BTV antenna.

Remove the existing three bolts and hardware at the bottom of the BTV mounting bracket. New replacement
stainless steel hardware is included in this kit (Figure 2).

Install the SO-239 into the bracket using the 5/8" star washer and 5/8" nut as shown in Figure 2. When
installing stainless steel hardware, it is suggested that JTL-12555 Jet-Lube SS-30 Anti-Seize be used to
allow easier future maintenance.

Position the bracket so the SO-239 is facing the direction you have chosen. Install the three new 10-24 x 1"
stainless steel bolts, five - #10 stainless steel star washers, and three 10-24 stainless steel nuts. On each of

two bolts that go through the bracket, place a star washer between the SO-239 bracket and the BTV
mounting bracket (Figure 2). The other three star washers are used between the nuts and the black
BTV base. Do not over tighten to avoid damage to the black plastic BTV base.

Figure 2

Install the insulated and weather sealed wire link terminal to the BTV antenna feedpoint using the new
spacer, star washer, terminal from the SO-239, flat washer, split washer, and Phillips head screw (Fig. 3).

Remount the antenna if you removed it earlier. When using a DXE-RADP-1P Radial Plate, connect the
optional coaxial cable jumper from the SO-239 bracket to the radial plate bulkhead connector.

Weatherproofing

After firmly attaching your existing coaxial cable PL-259 to the SO-239, the PL-259 and SO­239 should be weatherproofed using T3M Temflex™ 2155 rubber splicing tape which is a
conformable self-fusing rubber electrical insulating tape. For outdoor use, the rubber splicing
tape should be protected from UV deterioration with an overwrap of Scotch® Super 33+ for
all weather applications.

Peel back the protective covering. Tightly wrap the 3M Temflex™ 2155. When
wrapping, stretch the rubber splicing tape up to twice its normal length. Wrap tightly
around the coaxial cable and connectors. Overlap each wind of the tape by about 50%.
Use the Scotch® Super 33+2 as an overwrap to give the assembly UV protection. Cover
the 3M Temflex™ 2155 splicing tape completely.

Optional Items

3M Temflex™ 2155 Rubber Splicing Tape. Conformable self-fusing rubber electrical insulating tape. It is designed for low

voltage electrical insulating and moisture sealing applications. For outdoor use, it should be protected from UV deterioration with an
overwrap of Scotch® Super 33+

Scotch® Super 33+. Highly conformable super stretchy tape for all weather applications. This tape provides flexibility and easy

handling for all around performance. It also combines PVC backing with excellent electrical insulating properties to provide primary
electrical insulation for splices up to 600V and protective jacketing. Both tape products are available from DX Engineering.

JTL-12555 Jet-Lube™ SS-30 Pure Copper Anti-Seize 12555

Jet-Lube™ SS-30 Pure Copper Anti-Seize is the top choice of engineers and technicians in government, industry and leading Amateur
Radio contest stations, for protecting mechanical assemblies of aluminum tubing, general hardware and copper grounding systems. On
bonded metal surfaces Jet-Lube™ SS-30 assures electrical and RF conductivity while preventing oxidation and corrosion. Surpassing the
capabilities of other aluminum anti-oxidants, the wide temperature range of Jet-Lube™ SS-30 prevents long-term drying and caking, and
allows easy disassembly and effortless cleaning of parts. It contains a high concentration of copper flakes, a requirement for heavy loads
or compression; controlled frictional characteristics allow the surfaces of nuts and bolts to be tightened to their design torque
specifications. This anti-seize product assures full hydraulic efficiency by allowing the metal surfaces to slide over each other without
damaging metal-to-metal contact. Jet-Lube™ SS-30 is also designed to work as a similar and dissimilar component between two metal
surfaces to prevent seizing and galvanic action. The SS-30 compound formula improves conductivity and ground continuity - and will
not melt in high temperatures. Jet-Lube™ SS-30 Pure Copper Anti-Seize Features include: Meets MIL-PRF-907E spec, K-factor: 0.13,
Service rating: -65 degrees F (-54 degrees C) to 1800 degrees F (820 degrees C), SS-30 Resistivity (ohm-CM x 108) 5
