DX Engineering DVA - Dual Vertical Array System Features
The Dual Vertical Array System
is a monoband two element, three direction-switchable array
based on a two element end-fire/broadside combination of identical vertical elements. This antenna
array system is capable of delivering pattern directional performance superior to other systems in its
class.
Custom design with stable and clean low-angle patterns
No dump power as on other types of phased arrays so all your power goes to the antenna
elements
Power Handling: 2 kW continuous
Directional performance - Two End Fire and one Broadside directions
Forward Gain (approximate as compared to a single vertical): 3 dB End-Fire, 1 dB
Broadside (Omni)
Can be built with monoband verticals to cover any single band
RF Connectors: Three SO-239 (UHF Female): Transmitter, Antenna 1, Antenna 2
Excellent signal-to-noise ratio
Directivity over a very wide frequency range in the band selected
Excellent relay contact reliability
DC powered control console allows system operation without AC power mains
Control Cable: 3 conductors, minimum 20 AWG
Control Wire Connections: Set screw connectors internal at the Control Console and a
removable external connector at the DVA Phasing Relay Unit
Cover on the DVA Phasing Relay Unit made from tough UV protected plastic
Stainless steel chassis and mounting plate on the Phasing Relay Unit
DVA Control Console uses +13.8 Vdc input has three LEDs and three position rotary
direction switch (Position 1, Broadside, Position 2)
Designed, manufactured and tested by DX Engineering
