Introduction

This guide will explain the preparation of the most popular types of coaxial cable with solder-on
type PL-259 and solder type two piece solder-on Type N connectors using the various specialized
tools manufactured by DX Engineering. These specialized tools were designed by DX Engineering
and made in the USA to make the task of preparing coaxial cable easy, fast and safer than older
methods.

DE Engineering has four different coaxial cable preparation tool kits. Each kit has a variety of the
special tools with the DXE-UT-KIT4 being the most complete kit. Also, the individual tools are
available from DX Engineering separately. A complete list of the kits and tools it at the end of this
guide and can be viewed and ordered from DX Engineering online at www.DXEngineering.com or
by phone to DX Engineering: 800-777-0703

General Information

DX Engineering Coax Cable Stripping Tools provide a new way to prepare your 50 ohm coax cable
for the installation of solder type PL-259 (UHF-male) or 2-piece Type N connectors. These handy
coax cable strippers work on foam or solid dielectric cables with a precision, 2-step operation. DX
Engineering strippers are made with premium, long-lasting, tool steel, cutter blades for clean
coaxial cable preparation.

There are two different colored DX Engineering Coax Cable Stripping Tools
for the two most popular sizes (outside diameter) of coaxial cable:

The RED model DXE-UT-8213 prepares 0.405 inch OD coaxial cables:
DXE-213U, DXE-8U, DXE-11U, RG-213, RG-8, Belden 8267, 8214 and 8237.

The GREEN model DX-UT-808X prepares smaller coaxial cables such as

DXE-8X, RG-8X (mini 8) and Belden 9258.

Coaxial Cable Information for the DXE-UT-8213

The DXE-UT-8213 cutter blades (DXE-UT-RB-HD) are designed to cut through the more rigid
jacket materials such as PVC (polyvinyl chloride) or PE (polyethylene) encountered with high
quality coaxial cables having an OD of 0.405 inch.

There are some coaxial cable types on the market which use a jacket (outer insulation) material
which is soft and spongy, claiming ultra flexibility. These soft jacketed materials are sometimes
described as "thermoplastic elastomer" (found in UF Ultraflex types of coaxial cable) and are
characterized by their ability to be stretched and twisted free from the shield braid. As a result, the
DXE-UT-8213 cutter blade will twist the jacket and cutting action will stop - jamming the tool.
These unusually soft-jacketed cables demand to be stripped the old fashioned way. For these cables,
use the "finger stripper" model DXE-15035.

The following cables have been successfully stripped using the DXE-UT-8213 with our DX
Engineering Cutting Blades:

 DXE-213U
 DXE-8U
 DXE-11U
 Belden 8213 RG11/U
 Belden 8214 RG-8 foam
 Belden 8237 RG-8/U
 Belden 8267* RG-213/U

* Belden 8267 and Belden 9913F7: Some cable labeled as Belden 9913F7 (and also Belden 8267)
which has a very "squirmy" jacket and is easy to bend into all shapes without rebounding has
proven very challenging to strip easily. The jacket material seems different than the Belden (9913F7
and 8267) samples we had on hand from earlier lots that were used to test the DXE-UT-8213.
Belden was contacted concerning this and a sample of the suspect 9913F7 was sent for testing.
Belden informed us this was their cable (not a suspected counterfeit) and this is a known tolerance
in their manufacturing process of this type coaxial cable jacket. Therefore, the DXE-UT-8213 may,
or may not, work properly with some Belden 9913F7 or Belden 8267.

DXE-400MAX, Davis Bury Flex, Belden 9913, Times Microwave LMR-400 and LMR-240 are
not recommended to be prepared using these DX Engineering tools. These coaxial cable types have

an extra foil shield which is not suitable for soldering. DX Engineering, Amphenol Connex and
Time Microwave have crimp type connectors that should be used with coaxial cable having foil
shield.

Some coaxial cable center insulation may adhere to the center conductor more than others. In this
case when prepping the cable, the center insulation may not come off cleanly and will require a
sharp knife to completely remove it.

Using the DXE-UT-8213 and the DXE-UT-80P

The DXE-UT-8213 has been designed and manufactured to properly
cut coaxial cable for use with DXE-PL259 PL-259, Silver Plated,
PTFE Insulation PL-259 connectors or the DXE-N1001-S Type N
Male, Silver Plated, PTFE Insulation two-piece Type N connector
(requires a slight additional trimming of the cable center conductor
length - see text in this guide).

The following instructions show typical operation using

DX Engineering DXE-213U coaxial cable.

Items Used:

1. DXE-UT-8213 Coaxial Cable Stripping Tool

2. DXE-213U Coaxial Cable

3. DXE-PL-259 Coaxial Cable Connector

4. CNL-911 Coaxial Cable Cutter

5. DXE-170M Precision Shear Side Cutters

6. DXE-CGH-8U Coaxial Cable Gripper

7. Scissors

8. DXE-UT-80P Connector Assembly Tool for PL-259/RG-213-size Cable

9. 3M Temflex™ 2155 Rubber Splicing Tape - Used for weatherproofing

10. 3M Scotch® Super 33+ Vinyl Electrical Tape - Used for weatherproofing

A. Cut the end of the coaxial cable with the CNL-911 Coax Cable Cutter to get a good flush cut.

B. You want the coaxial cable to be round and not oval when viewed from the end. If the coaxial

cable is slightly oval, gently use the CNL-911 to round out the end of the coaxial cable.

C. Place the prepared coaxial cable end into the body of the DXE-UT-8213 labeled "1ST CUT".

D. Firmly grip the coaxial cable and the DXE-UT-8213, turn the DXE-UT-8213 in a clock wise

direction while applying steady and slightly firm pressure. Grip the coaxial cable between your
thumb and first finger, close to the tool.

To better hold the coaxial cable straight and make the coaxial cable easier to grip, use the DX
Engineering Hinged Cable Gripper tool (DXE-CGH-8U). This patent pending two-piece red
hinged cable gripper is custom made to fit and help you hold RG-213 or 8U sized coaxial cable
when using the DXE-UT-8213 coaxial cable prep tool. The surfaces that contact the coaxial cable
have horizontal grippers and on the outside of the tool, the knobby finish helps you maintain a sure
grip on the coaxial cable being prepared. The two halves are connected together with a spring
hinge to keep the tool in the right position and allow a sure grip every time.

Additionally, if the outer covering is older and dried out, it may stick inside the DXE-UT-

8213. One suggestion is to put a very light coating of cooking oil or other similar lubricant on
the coaxial cable outer covering for about 1", then insert it into the DXE-UT-8213.

Take care to keep the oil away from the exposed coaxial cable end.

Do not use any silicone based lubricant since the silicone may interfere with soldering.

E. As you turn the tool clockwise, the DXE-UT-8213 will begin cutting. Keep turning the tool in

a clockwise direction until it will not cut anymore, the tool will eject the cut parts and stop
cutting at the proper length.

Remove the coaxial cable from the DXE-UT-8213.
