DXE-UN-43 - UNUN - 4:1, High Power, for use with Non-Resonant Verticals
DX Engineering high power transmission line transformers with Maxi-Core
TM
Technology allow your antenna to
perform to its full potential and reduces the stresses on your equipment more efficiently than similar competitive
products. This UNUN is specifically designed for application with 43-foot non-resonant multi-
band antennas - assuring the best efficiency from your antenna and transmission
line/tuner installation. This results in minimizing the additional transmission lines losses
caused by SWR. It can be added to any existing 43-foot antenna installation, or used to replace
an older competitive UNUN for a performance increase.
1.8 – 30 MHz operating range to cover popular amateur bands.
Handles rated power with minimal energy loss so there is no thermal related failure.
Ratio - 4:1
Impedance: 200 ohms to 50 ohms - optimized for 43 ft verticals
Power Level – 2 KW / 5 KW PEP
Frequency Range – 1.8 to 30 MHz
Weatherproof NEMA enclosure
Silver / Teflon SO-239 input connector
2-3/8" x 4" x 4" inches (HxWxL)
DXE-UN-BRKT - UNUN Mounting Kit for Multi-Band HF Verticals (patented)
This mounting kit allows you to mount a DXE-UN-43 UNUN at the base of any 43-foot Multi-Band vertical antenna.
The aluminum mounting plate may be clamped to any 2" OD aluminum tubing element with the studded element
clamps supplied. The UNUN is isolated by its plastic weather proof case, providing the simplest
add-on installation. Works with the DXE-UN-43 UNUN, or similar competitive UNUNs and
Baluns which use the same weatherproof NEMA case.
Kit includes:
Aluminum Mounting Plate
Studded Stainless Steel Element Clamps
Stainless steel mounting hardware
DXE-TCB-UNFK - Feed Point Connection Kit, UNUN to Vertical Antenna
This kit consists of two tinned copper braid straps for connection between a DXE-UN-43 UNUN and the ground radial
system and feedpoint of a vertical antenna. The straps are the correct length to allow short, low inductance connections -
flexible for allowing use of a tilt base with the antenna. The length is 9" from center to center of the preformed 1/4"
holes. If longer lengths are required, you may purchase the DXE-TCB-100 tinned copper braid by the foot for your
own fabrication.
Length: 9" center to center of the 1/4" holes
Width: 1’’
Thickness: .045’’
Width and thickness may vary slightly as the flexible braid is stretched or compressed.
DXE-RADP-3 - Radial Plate, Stainless Steel with 20 Sets of SS Radial Attachment Hardware
The patented DX Engineering Radial Plate is meant for those of you that have or are building a quarter wave
vertical antenna and who want an easy, neat and effective way to connect those essential radial wires and the coax
to your vertical antenna for the lowest takeoff angle and strongest signals. DX Engineering Radial Plate is laser
cut from tough stainless steel so that it has smooth edges, won’t corrode and will always look good. You will be
proud of how good your installation looks. This plate will work perfectly with most commercially available
vertical antennas such as the Hustler BTV series (4-BTV thru the 6-BTV), the SteppIR (BiggIR or SmallIR) or
one of your own construction
