The DX Engineering Balun or Feedline Choke Mounting Plate and Bracket Kit provides a variety of
mounting solutions for a DX Engineering Maxi-Core® 20 Balun or the DX Engineering Maxi-Core® 20
Current Choke on a variety of antennas.

Other Baluns or feedline chokes using the standard 4 x 4 x 2 inch plastic NEMA boxes can also use this
mounting kit with its rugged pre-drilled polymer plastic plate and stainless steel bracket with stainless steel
hardware.

The DX Engineering Balun or Feedline Choke Mounting Plate and Bracket Kit can be used at the base of any
vertical, on the boom of a Yagi or beam antenna, or even on a mast or post. The unique perpendicular mount
provides a beneficial separation between the ferrite of the balun or choke and the metal tubing of the antenna
or mount, resulting in improved choking performance. The UV black high-strength polymer mounting plate
provides additional isolation between the feedline and the antenna system for optimal performance and
decoupling.

The stainless steel mounting bracket has laser cut holes for any one of these optional heavy-duty DX
Engineering V-Saddle Clamps.

 DXE-CAVS-11P for 1/2 to 1-3/4 inch OD aluminum tubing
 DXE-CAVS-2P for 1 to 2 inch OD aluminum tubing
 DXE-CAVS-3P for 2 to 3 inch OD aluminum tubing
 DXE-SSVC-2P for 1 to 2 inch OD for steel pipe
 DXE-SSVC-3P for 2.375 to 3 inch OD steel pipe

No optional clamps are necessary when attaching this Mounting Plate and Bracket Kit to a 4” x 4” or 6” x 6”
wooden post for vertical. Use two suitable wood lag bolts or carriage bolts from your local hardware outlet
store.

Kit includes:

 Polymer mounting plate, pre-drilled
 Stainless Steel adaptor bracket
 Stainless steel mounting hardware

Note: JTL-12555 Jet-Lube SS-30 or other Anti-Seize must be used on all clamps,
bolts and stainless steel threaded hardware to prevent galling and to ensure proper
tightening.

Assembly

Assemble the Stainless Steel bracket to the polymer mounting shelf using the Hex Head Bolts, Flat Washers,
Split Washers and Nuts as shown.
