Introduction and General Information

 

 

Congratulations on your purchase of the 

DX Engineering Dual Vertical Phased Array System,

 

custom designed and tested to offer the best directional transmitting and receiving performance in 
proportion to the space required. Advanced design, with a stable, clean and low-angle pattern makes 
the DX Engineering Dual Vertical Phased Array (DVA) the finest dual element quarter-wave 
monoband phased antenna system available. The DX Engineering Dual Vertical Phased Arrays are 
advanced vertical antenna phasing systems that set new standards in two vertical element array 
performance. DX Engineering Dual Vertical Phased Array system design eliminates the waste load 
port of previous hybrid-type two-element systems, thus increasing array efficiency. Each mono-
band Dual Vertical Array system includes a sleek new Phasing Relay Unit and a new Control 
Console. The model number of your system corresponds to the band for which it was manufactured. 
 
There are 10 system models available that cover 160 through 10 meters:
