Introduction 

 
The DX Engineering 

MBVE-2

 is a fast taper 33 feet high multi-band vertical antenna system. The 

vertical antenna operates from 80 meters through 10 meters using a good quality outboard customer 
supplied tuner. There are no traps, coils or linear loading elements to rob power. Designed with 
6063 corrosion-resistant aluminum tubing and stainless steel hardware, this antenna is very durable 
and attractive.  An extra tubing section is part of the design to provide final length adjustment from 
33 feet to 36 feet if necessary. 

 
Features 

The 

DXE-MBVE-2

 vertical antenna system includes the antenna elements, stainless steel element 

clamps, mounting plate assembly, Tilt Base, and stainless steel hardware. 

 

 Full band coverage from 80 through 10 meters - Outboard customer supplied tuner required 

 

 33 to 36  ft overall height 

 

 Includes the 

DXE Tilt Base

 

 

 Fast Taper from rugged base to sleek top for low wind resistance 

 

 No Coils or Traps – Maximum Radiation Efficiency 

 

 Power Handling up to 5 kW - built to last 
 
 
 

WARNING! 

 

INSTALLATION OF ANY ANTENNA NEAR POWER LINES IS DANGEROUS 

 
 
 
 

Warning

:

 Do not locate the antenna near overhead power lines or other electric light or power 

circuits, or where it can come into contact with such circuits.  When installing the antenna, take 
extreme care not to come into contact with such circuits, because they may cause serious injury or 
death.  
 

Overhead Power Line Safety 
 

Before you begin working, check carefully for overhead power lines in the area you will be 
working.  Don't assume that wires are telephone or cable lines: check with your electric utility for 
advice. Although overhead power lines may appear to be insulated, often these coverings are 
intended only to protect metal wires from weather conditions and may not protect you from electric 
shock 
 
Keep your distance! Remember the 10-foot rule:  When carrying and using ladders and other long 
tools, keep them at least 10 feet away from all overhead lines - including any lines from the power 
pole to your home.
