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.

Mount an optional Maxi-Core® 20 Balun or Maxi-Core® 20 Current Choke to the Polymer mounting
shelf using the Hex Head Bolts, Flat Washers and Nyloc Nuts as shown. Mount it in the desired position for
your installation.
To mount the completed assembly to your existing mounting pipe, an optional DXE-SSVC-2P V-Bolt
Saddle Clamp will be needed. Below are photos showing a typical installation of the Feedline Current
Choke and Mounting Kit for a Hustler BTV antenna.
Choke Mounting Bracket is shown with optional BTV antenna, Omni-Tilt Base,
Radial Plate and 2 foot jumper cables mounted to customer supplied 2" OD mounting pipe
using one optional DXE-SSVC-2P Mounting Clamp.
To mount the completed assembly to your existing antenna, an optional clamp (depends on your boom
diameter) will be needed. Below are photos from N9JCS showing a typical installation of the DX
Engineering Maxi-Core® 20 Balun on a Yagi antenna.
