Installing the UNUN
When used with the optional
DXE-UN-BRKT
, the UNUN may be attached to the 2" OD base
section of any non-resonant 43 foot tall
vertical antenna system, including your
own home-brew creation. It also shares
the same mounting footprint as other
similar competitive products, so
it may be easily substituted in existing
installations for superior performance.
The
DXE-UN-43
may also be mounted
on a wood post or other mounting
scheme using your own hardware.
The optional
DXE-UN-BRKT
comes
with: One UNUN Bracket, four #6 x
3/4" long Stainless Steel Hex Head
Bolts, eight #6 Stainless Steel Flat
Washers, four #6 Nyloc Nuts, two
Custom 90 degree Studded Element Clamps, two #10 Nyloc Nuts, two 1/8" thick Aluminum
Spacers and four #10 flat washers.
The UNUN should be mounted with the SO-239 connector facing downward to allow drainage of
any condensation from the weep
holes in the high impact plastic,
weather sealed NEMA-spec case.
Mount the UNUN to the UNUN
Bracket using the hardware as shown.
The custom studded element clamps
are mounted to the UNUN Bracket as
shown.
As with all coaxial cable connections,
you should use
TES-2155
3M
Temflex™ Rubber Splicing Tape, with an overwrap of
TES-06132
Scotch
®
Super 33+ Vinyl
Electrical Tape for weatherproofing.
A good RF connection must be made from the UNUN to both the vertical radiator and the radial
system. DX Engineering offers the optional
DXE-TCB-UNFK
UNUN
Feedpoint Connection Kit that contains two 1” wide x 9" long copper
tinned braids soldered and drilled on each end with a 1/4” hole for easy
connection to the UNUN. If your application requires a different connection style or layout, DX
Engineering can assist you. Call DX Engineering for suggestions.
