DX Engineering Radio RF Ground Plane Kits provide an effective method of reducing stray RF
pickup by equipment and interconnecting cables. Used under and in back of equipment, this 1/16
inch thick, pre-drilled copper sheet creates an RF reference plane that is typically connected to the
existing grounding bus, or it may be used as a grounding bus. As described in

the ARRL’s “Grounding and Bonding for the Radio Amateur” by H. Ward

Silver, N0AX; a large surface area of metal improves upon the single conductor
grounding bus by equalizing the RF E-field (electric field) around equipment
and attached cables. This reduces voltage differences between pieces of
equipment and associated currents that cause RF interference to transceivers,
microphones and accessories. The reduction in RF interference improves both
transmitted and received signal quality.

As used by top contesters and DXers alike, this type of flat metal sheet placed
under equipment, along with physically short grounding braids, wires and
interconnection cables can significantly reduce the RF voltage differences
between cables and equipment. The chance of RF trouble in your equipment is
reduced by installing DX Engineering Radio RF Ground Plane Kits in your
station.

NOTE: These are indoor radio equipment RF ground planes, which are not to be confused with a
ground plane or radial system on a vertical antenna. The only interconnection between any antenna
and this Radio RF Ground Plane is incidental, through the shield of properly protected and
grounded coaxial cable which is connected to the station RF bonding bus and grounding system.

Radio RF Ground Plane Kits Available

The Radio RF Ground Plane Kits are available in six versions; three sizes of copper plate with
hardware and the same three sizes copper plates with companion mounting boards made of Medium
Density Fiberboard (MDF), with hardware. All kits are intended for indoor use only:

The following chart shows typical transceiver size information to help you choose the size copper
plate you require. You can also use two or more copper plates beside each other if you need a larger
copper plate area.

If your particular transceiver is not listed, just measure to determine the size you require.

The copper plates are also recommended for use with RF amplifiers, Tuners and any

other Amateur Radio active components.

It is possible to spray paint on copper. The metal should be clean and dry, and an epoxy primer may
be applied before spray painting to promote adhesion. Make sure the paint is specifically made to
cover metal. Many brands and colors are available and they are readily found at hardware stores.

Remove the plastic protection from the front of the copper plate and, while wearing a particle dust
mask and nitrile gloves, sand the surface with fine-grit sandpaper, taking great care to sand the
entire surface thoroughly. Once the sanding is completed, clean the surface with denatured alcohol
and a clean cotton rag or paper towels. Keep clean nitrile gloves on during this process to ensure
that the oils of your skin do not come in contact with the copper plate. Tape off the areas where the
connections are made to the copper plate to ensure adequate electrical/RF connections.

Assembly

The following assembly uses the DXE-RG-SCB Radio RF Ground Plane Kit with the MDF Board

and hardware. Also shown are optional DX Engineering Tinned Copper Braid straps.

Tools Required

7/16” Nut Driver, 7/16” Wrench, Phillips Screw Driver

1. Mount the Copper Sheet to the MDF Board using the four self tapping screws as shown below.

Note: The Copper Ground Plane is longer than the MDF Board with the four larger holes for

grounding connections and multiple ground plane interconnections. This is done to allow room
for the hardware used to attach tinned copper braid, copper strap or wires to equipment and the
radio room single point ground.

2. Set your equipment in place on the RF Ground plane and measure the length(s) of Tinned Copper

Braid needed. Keep the lengths as short as possible.

3. Attach the Tinned Copper Braids to the
equipment and to the Copper Ground Plane
using the 1/4” hardware included in the kit.
Use of the DXE-CCK Copper Cleaning Kit
is suggested.

Note: You can attach conductors to the Copper Ground Plate in different methods. Choose the

method that best suits your application. Once the equipment is attached, also run a heavy
conductor or copper strap as the ground line to the ground bus or to the single point ground
panel, such as the DXE-SPGP where cables enter the radio room and connect to protectors.

Keep the braids as short as you can.

Suggested Parts

DXE-CCK - Copper Cleaning Kit - Includes 1 oz. of LB 8008 Loctite® Copper Based

Anti-Seize, 3 Scotch-Brite® Cleaning Pads, 1 Paste Brush, 9 Finger Cleaning Packets.

DX Engineering Tinned Copper Braid Assemblies with 1/4” Ring Terminals - The
DX Engineering Tinned Copper Braided Straps come in various lengths and have Ring
Terminals soldered at each end. You can also get custom made assemblies to your exact
length specifications by using the Custom Cable Builder on the DX Engineering web
site.

You can also purchase the Tinned Copper Braid in various widths by the foot from DX Engineering
(DXE-TCB-038 / 050 / 063 / 075 / 100) and make them to your specified lengths.
A suggested method to make your own short custom length tinned copper braid jumpers:

1. Cut the Tinned Copper Braid to the length you want.

2. Trim

3. Solder each end.

4. Once the part has cooled, drill mounting 1/4” holes on each end.

This is ideal since you can easily make them short.

DX Engineering also has two feedpoint kits that have pre­made 1” wide Tinned Braided Straps that can be used as
well. DXE-TCB-FPK has one 8” and one 9” braid. The
DXE-TCB-UNFK has two 9” braids.
