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 aluminum 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 aluminum plate with hardware and the same three sizes aluminum 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 aluminum plate you require. You can also use two or more aluminum plates beside each other if you need a larger aluminum plate area.
If your particular transceiver is not listed, just measure to determine the size you require.
The aluminum plates are also recommended for use with RF amplifiers, Tuners and any

It is possible to spray paint on aluminum. The aluminum 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 aluminum. Many brands and colors are available and they are readily found at hardware stores.
Remove the plastic protection (if present) from the front of the aluminum 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 aluminum plate. Tape off the areas where the connections are made to the aluminum plate to ensure adequate electrical/RF connections.

Assembly
The following assembly uses the DXE-RGP-MAB Radio RF Ground Plane Kit with the MDF
Board and hardware. Also shown are optional DX Engineering Tinned Aluminum Braid straps.
1. Mount the Aluminum Sheet to the MDF Board using the four self tapping screws as shown below.
Note: The Aluminum 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 Aluminum Ground Plane using the 1/4” stainless steel hardware included in the kit. Use of the DXE-CCK Copper Cleaning Kit or JTL-12555 Jet­Lube-SS-30 is suggested.
Note: You can attach conductors to the Aluminum 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.

Suggested Parts
DXE-CCK - Copper Cleaning Kit
JTL-12555 - Jet-Lube SS-30 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.
