The UNUN has two 1/4-20 connection points and have Wing Nuts
and Flat Washers used for connecting braided feed wires to the
antenna feedpoint and radial system. The antenna feedpoint must be
connected to the positive phase terminal on the
DXE-UN-43
UNUN
closest to the

DX Engineering Multi-Band Vertical Antenna Systems
The
DXE-UN-43
is an enhanced replacement for the 4:1 Balun on the DX Engineering Multi-Band
vertical antenna systems.
Remove the coaxial cable connection from the 4:1 Balun and the two braided feed lines going from
the Balun to the Radial Plate and the antenna feedpoint connection bolt.
Remove the Balun and Balun Shelf from the mounting pipe.
Loosen the Tilt Base bolts for lowering/raising the vertical antenna. Carefully tilt the antenna to the
down position. Ensure you have some support system (table, saw horse, etc.) to support the antenna
while in the down position.
Repositioning the Feedpoint Connection
Hardware
Loosen the two 2" U-Bolt Saddle Clamps holding
the base section to the insulated channel.
Loosen the element clamp located at the top of the
base section and rotate the base section so the
feedpoint is pointing to the left (as you look at the
antenna from the front).
Also ensure there is 1-3/4" between the bottom of
the U-Bolt and the antenna feedpoint hardware.
Tighten the two 2" U-Bolt Saddle Clamps and the
element clamp at the top of the base section.
