Universal Copper Grounding Clamp

DXE-UCGC-Z

The DXE-UCGC-Z Universal Copper Grounding Clamp is
custom designed to provide a mounting platform for various
types of lightning protectors commonly used for Amateur
Radio. The “Z” design makes it easy to install and remove
coaxial cable connectors. Ideal for both permanent installations
and for temporary installations such as Field Day.

The DXE-UCGC-Z Features:

 Made from 1/16” thick Copper Alloy 110 for maximum

conductivity with a “Z” bend for easier installation and
removal of coax connectors

 Easy to assemble two-piece construction. Each plate is approximately 3-1/4” wide x 4-3/16” tall.
 Fits common standard 5/8” through 3/4” diameter ground rods.
 Using this copper clamp is faster and easier than building up the joint for an exothermic weld.
 1/4” Stainless Steel hardware is included: Eight 1/4” Flat Washers, four 1/4”-20 Nyloc Hex Nuts and

four 1/4”-20 x 3/4” long Hex Head Bolts.

The DXE-UCGC-Z can easily mount up to six lightning
protectors. The photo shows two DX Engineering and
two PolyPhaser lightning protectors installed on a DXE-
UCGC-Z mounted to a 5/8” diameter ground rod. Other
lightning protection products can also be mounted, such
as the DXE-IS-RCT Control Line Protector and Alpha
Delta Lightning Protectors.

An anti-seize compound such as JTL-12555 Jet Lube
SS-30 Pure Copper Anti-Seize must be used on the
threads to prevent galling or seizing of stainless steel
hardware. All connections must be generously coated

with a conductive joint compound to prevent
moisture penetration and enhance conductivity such as JTL-12555 Jet Lube SS-30 Pure Copper
Anti-Seize. DX Engineering’s DXE-CCK Copper Cleaning Kit contains the proper joint cleaning

compound, brush and cleaning pad to properly prepare the copper surfaces.

Choose your mounting scheme and position

the lightning protectors (in this example 2 DX

Engineering and 2 PolyPhaser lightning
protectors) where you want them.

Depending on the types and positions, the
four hex head 1/4”-20 bolts, eight flat washers
and four Nyloc nuts used to hold the two copper
plates together may be loosely installed. In this

example 3 of the hex bolts go in one

direction while the fourth one is reversed to
allow clearance for one of the PL-259 connectors. Use the mounting hardware that comes with the

2

individual lightning protectors to attach them. The lightning protectors and copper clamp plates must be
thoroughly cleaned to remove any oxidation where surfaces mate to each other.

Once the position of the protectors is established and the four hex head bolts, eight flat washers and four
Nyloc nuts are installed, you can mount the DXE-UCGC-Z on your existing ground rod. Tighten the four
bolts evenly until the plates are flush to each other. Note: Some distortion of the copper plates may occur
while tightening.

Prior to attaching the lightning protectors, you may
want to install the proper coaxial cable lines to the
protectors and weather seal the PL-259 connectors
using 3M Temflex Rubber Tape with an overwrap
of 3M 33+ Vinyl Tape or 3M Super 88 Vinyl Tape.
Also, the lightning protector bodies are not
weatherproof and it is suggested to use the DX
engineering WK-1 Weatherproofing kit, or
completely tape the body of the protectors using the
same weatherproofing tapes as you used on the
connectors. Some users have also suggested
covering the entire assembly with a plastic food
container or plastic trash bin.

As with all electronic equipment, take proper safety considerations. For example: Do not install if there is
a storm anywhere in your area. Do not adjust or touch the grounding system equipment when there is a
storm anywhere in your area. Make sure all power is removed before making any adjustments or working
on any ground system or grounding components.
