Universal Wire Antenna Kits
offer an easy, high quality route to building your own
design wire antennas.
The kits are lightweight yet rugged in design that will allow construction of single band resonant
dipoles, folded dipoles or any center or off-center fed wire antenna you select. If fed with ladder
line, it is usable with a tuner for multi-band operation on all the HF bands. It’s ideal for portable or
tactical use, and permits you to build antennas which can be easily installed in attics, small lots or
Covenant Condition Restricted (CCR) locations.
The Universal Wire Antenna Center Support and End Insulators are made of light weight, high
strength UV-protected material. The Center-T is designed to serve as a feedpoint and strain relief
for antennas made with either wire or ladder line, which may be fed with either ladder line or
coaxial cable. They feature an exclusive serpentine wire grip for insulated DX Engineering Antenna
Wire and high strength, high power 300 Ω Ladder Line. The serpentine connection’s grip is strong
enough to permanently support the antenna wires without the need for looping or wrapping the wire
ends. This allows fast and easy field adjustments of antenna length without soldering. Each kit also
includes crimp-on ring terminals for ladder line and antenna wire and connection hardware. The DX
Engineering
DXE-UWA8X
and
DXE-UWA213
kits include a strain relief bracket and P-Clamps
with neoprene cushions that grip the coaxial cable without deforming it, taking the weight of the
hanging cable off of the connector.
The ladder line feed configuration can be used successfully with the balun incorporated in most
high quality antenna tuners to obtain a low SWR across the entire frequency range. Using a DX
Engineering external current balun may provide better performance and permits converting to
coaxial cable prior to entering the operating position which will reduce RFI. DX Engineering
Baluns, Antenna Wire, 300 Ω Ladder Line and Support Rope are optional items that are available to
make a complete antenna package.
Refer to the end of this assembly manual for information on construction of a few simple dipole
antennas using these kits. For more complete antenna theory and for construction of the many
different types of wire antennas possible with the DX Engineering
