DXE-UN-43 - UNUN - 4:1, High Power, for use with Non-Resonant Verticals
DX Engineering high power transmission line transformers with Maxi-Core
®
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.

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 patented (US Patent No.
D597,086) mounting plate may be attached to any 2" OD aluminum tubing
element with the studded element clamps supplied. Works with the DXE-
UN-43 UNUN, or similar competitive UNUNs and Baluns which use the
same size weatherproof NEMA case.
Kit includes:

High Strength Insulated Mounting Plate

Custom Studded Stainless Steel Element Clamps

Stainless steel mounting hardware
DXE-TCB-UNFK-WR - Feed Point Connection Kit, UNUN to Vertical Antenna
This kit consists of one tinned copper braid strap for connection between a DXE-UN-43 UNUN and the feedpoint of the
vertical antenna. The strap is 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.

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.
