DX Engineering DVA Phasing Relay Units are the band specific parts of the Dual Vertical Array Systems. These are larger, new Phasing Relay Units for any HF band, 160 through 10 meters. New heavy-duty components handle 2 kW continuous RF power for array performance at low SWR over a wide bandwidth. These mono-band weatherproof DVA Phasing Relay Units include a clamp for mounting directly between two ground-mounted, full-size, quarter-wave resonant verticals.

Their companion DXE-EC-DVA Directional Control Console is a 3-direction array pattern selector that operates on 13.8 Vdc and features a 3-position rotary switch, directional LED indicators and scratch pads..

Dual Vertical Array end-fire directional patterns achieve a real front-to-back over 20 dB with typical array forward gain up to 3 dB over a single vertical.

Specifications for the DX Engineering Dual Vertical Array:

* Forward Gain (approx., compared to single vertical): 3 dB End-Fire; 1 dB Broadside-Omni
* Front-to-back: Over 20 dB nominal, end-fire patterns
* Power Handling: 2 kW continuous
* RF Connectors: Three SO-239 (UHF female); Transmitter, Antenna 1, Antenna 2
* Control Cable: 3 conductors, min. 20 AWG
* Control Cable Set-Screw Connectors: Relay Unit--external; Control Console--internal

DX Engineering Dual Vertical Array mono-band phasing systems are available for each HF band, with 160, 80 and 40 meters in stock, and 60 30, 20, 17, 15, 12 and 10 meter systems available by special order. Your phased array pattern results may vary, due to band conditions, the surroundings at antenna and the radial system installation. Additional information is in the Dual Vertical Array instruction manuals, linked at each system description web page.
