Introduction

Note: JTL-12555 Jet-Lube SS-30™ should be used on all bolts and stainless steel threaded

hardware to prevent galling and to ensure proper tightening.

The DXE-VMN-1 Vertical Antenna Matching Network is custom designed for use with the
Hustler® 5-BTV and 6-BTV and other quarter wave monoband vertical antenna systems. In some
installations of these antenna systems, achieving minimum SWR on the 80 meters may be difficult.
The DXE-VMN-1 Vertical Antenna Matching Network will aid in tuning the customer selected
portion of the 80 meter band to the minimum SWR.

While the example shown in this manual is the Hustler® 5 or 6-BTV, the Vertical Matching
Network may be installed between ground and the feedpoint of any monoband quarter wave
base-fed vertical antenna.

Features - The DXE-VMN-1 Vertical Antenna Matching Network:

 Precision machined Coil Tube
 Highest quality 12 gauge solid tin coated coil wire
 Custom made silver plated DXE-CLIP-P Coil Tap
 Custom "L" Bracket for mounting on the optional DXE-RADP-3 Radial Plate
 Stainless Steel Mounting Hardware
 #14 Stranded Copper Wire with Terminals for connection to the Hustler antenna
 Handles full legal limit
 Inductance: 300 kHz to 7 MHz = 5.6 µH, 14 MHz = 7.2 µH,

21 MHz = 8.5 µH, 28 MHz = 8.0 µH

Tools Required

Medium size Phillips head screwdriver (#2) for BTV Feedpoint screw
Small size Phillips head screwdriver (#1) for Coil Tap screw
Two 7/16" Wrenches, or one 7/16" Nut Driver and one 7/16" wrench
