DXE-GBWM-INS Rev 0
The DX Engineering DXE-GBWM Copper Ground Bus Wall Mount is a very rugged copper alloy product for mounting up to four coaxial surge protectors, or a combination of lightning protectors and ground braid straps. Heavy
0.094 in. copper prevents twisting or flexing from the weight of long coax cable runs. The DXE-GBWM ground bus comes with two ground lugs, two ring terminals and stainless steel hardware.
The DXE-GBWM features:

Can hold up to four coaxial cable lightning surge protectors or a combination of lightning surge protectors and grounding braids for equipment ground connections

May be used indoors or outdoors

Supplied copper lugs handle ground wires from 14 to 4 AWG to attach to Single Point Grounds
(SPG), station grounds or ground rods

Crimp ring terminals are provided for additional ground-wire connections

Wall mounting screws are common types (number 10 pan head or common black drywall screws) are user-supplied
The hardware is supplied for mounting the two ground lugs and the two ring terminals on the sides of the
DXE-GBWM . Hardware for mounting other items to the ground bus are user supplied.
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.
The pictures in this instruction sheet are for illustration purposes and only show a few of the possibilities for mounting various items to the DXE-GBWM . Optional parts such as lightning protectors, ground braid straps and their associated mounting hardware are shown. Mounting the DXE-GBWM to a wall, wall stud or other sturdy mounting area (vertically or horizontally) is accomplished with user supplied hardware.

Shown with optional items
PolyPhaser Coaxial Lightning Protectors
PolyPhaser Coaxial Lightning Protectors are designed for general, single-transmitter use in the 1.5 to 700 MHz frequency range. "Flange Mount" protectors anchor to a grounding panel with both connectors parallel to that flat surface. PolyPhaser
Coaxial Lightning Protectors use a DC blocked specially configured gas tube design that has no DC continuity between the two center pins. PolyPhaser's multi-strike products are designed to pass RF frequencies and block all DC. These protectors appear as a DC open between surge and protected ports and offer the best protection in the industry.
Part Number Description
PPR-IS-50UX-C0 Coaxial Lightning Protector, Flange Mount, 1.5-700MHz, HF 2kW, VHF 375W, DC Block, UHF Female, 50 ohms
PPR-IS-50NX-C0 Coaxial Lightning Protector, Flange Mount, 1.5-700MHz, HF 2kW, VHF 375W, DC Block, N Female, 50 ohms
Alpha Delta Coaxial Lightning Protectors
Alpha Delta UHF Connector Coaxial Cable Surge Protectors have SO-239 connectors and are rated for 200 or 2,000 watts at frequencies up to 500 MHz. They are not DC-blocked, so they will pass control voltages in applications requiring the coaxial cable to carry both RF and DC voltage. They can be easily mounted for the most effective grounding with their 1/4-20 in. stud in a single hole or as a bulkhead through the grounding panel. Through the careful design of the Alpha Delta Arc-Plug
® gas tube module and precision, constant impedance through-line allowing proper firing characteristics, these devices are designed to provide effective protection throughout this entire spectrum.

ALF-ATT3G50U Surge Protector, Coaxial, DC pass, UHF Female, SO-239, 200 W Power Rating

DX Engineering Ground Braid Assemblies
Quality tinned copper braid in 5 widths for grounding applications. Preassembled with lugs in selected widths and lengths - for both #10 and 1/4" bolt sizes. Contact Customer Service for special lengths or terminations. Sold per foot to accommodate almost any project. Very long per-foot lengths may not be continuous. Contact Customer Service to discuss your length needs if continuous length is required. A major use of the Grounding Straps for amateur radio operators would be to ground one's rig, amp, etc. to a copper strip running behind the desk which acts as the central ground point for the equipment. This central point equipment ground would then be routed away with heavy copper strap to join any other similarly protected branches for
SPG single point grounding.
