Balun Mounting Bracket

US Patent No. D597,086

DXE-BMB-4P

DXE-BMB-4P-INS Rev 2

This custom made patented Balun Mounting Bracket and Stainless Steel Hardware Kit will allow you to mount
your quality DX Engineering Maxi-Core® 20 Balun directly to a
boom or pipe. When used with optional DXE-ECLS Stainless
Steel Band Clamps with Studs, you can mount the Balun Mounting
Bracket on a boom or pipe ranging in size from 1/2” to 3-1/4”.

The unique design provides minimum capacitive coupling to the
wire and field surrounding the Balun core plus a special UV
resistant, strong black plastic compound.

This custom made Balun mounting bracket will fit other
manufacturers’ similarly packaged Baluns and includes the
stainless steel Balun mounting hardware.

Use the included Stainless Steel Hardware to mount the Balun as
shown below. Choose the appropriate sized optional DXE-ECLS
clamps and install them on the Balun Mounting Bracket as shown below. When installing stainless steel
hardware, it is suggested that Jet-Lube SS-30 Anti-Seize (JTL-12555) be used to prevent thread galling.

Below are examples of the Balun Mounting Bracket in use. Use of the

DXE-BALUN-WK Wire kit is recommended. Wires are shown below in Red for clarity.

Stainless Steel Band Clamps with Stud

These marine grade stainless steel band clamps are great for mounting items or making connections to a tube or pipe with an outside diameter ranging from

0.50" to 3.25". Each stainless steel band clamp has a 3/4 inch long, 10-24 stud welded to it, which allows attachments without drilling holes that could
weaken element or tower tubing. Stainless steel attachment hardware consisting of flat washers, split-ring lock washers, external star washers and 10-24 hex
nuts are included.

JTL-12555 Jet-Lube™ SS-30 Pure Copper Anti-Seize 12555

Jet-Lube™ SS-30 Pure Copper Anti-Seize is the top choice of engineers and technicians in government, industry and leading Amateur Radio
contest stations, for protecting mechanical assemblies of aluminum tubing, general hardware and copper grounding systems. On bonded metal
surfaces Jet-Lube™ SS-30 assures electrical and RF conductivity while preventing oxidation and corrosion. Surpassing the capabilities of other
aluminum anti-oxidants, the wide temperature range of Jet-Lube™ SS-30 prevents long-term drying and caking, and allows easy disassembly and
effortless cleaning of parts. It contains a high concentration of copper flakes, a requirement for heavy loads or compression; controlled frictional
characteristics allow the surfaces of nuts and bolts to be tightened to their design torque specifications. This anti-seize product assures full
hydraulic efficiency by allowing the metal surfaces to slide over each other without damaging metal-to-metal contact. Jet-Lube™ SS-30 is also
designed to work as a similar and dissimilar component between two metal surfaces to prevent seizing and galvanic action.
