20 Meter Dipole Antenna.
The W2AU is the preferred Balun of Amateurs worldwide.
W2AU’s operate at a low VSWR from 1.8 to 40 mHz, and handle powers up to 2 KW PEP (at SWRs of less than 3:1).
W2AU Baluns are transformer designs with ferrite cores to provide 95% minimum coupling efficiency.
Each has a built-in lightning arrestor, hang up hook, and 600 lbs of pull-apart strength in a weatherized, rugged package using only stainless steel hardware and quality materials.
The 1:1 matches 50(75) ohms unbalanced coax to 50(75) balanced dipoles.
Each dipole is cut for near the low end center of their respective bands , i.e. 3.700 MHz. However, generally these antennas are broadbanded and it is not unusual for there to be an acceptable SWR of less than 2:1 across the entire band.
Poly-STEALTH ™ High Strength Aerial Wires are manufactured with high strength, high conductivity Bare Copper-Clad Steel (BCCS) and insulated with a high quality UV Resistant Polyethylene to provide you with one of the strongest and longest lasting antenna wires on the market today.
The strongest wire of the group is ideal for the longest of wire runs with or without additional support.
Ideal balance of strength and flexibility
Low-Gloss finish and small size makes wire disappear into the background
Superior abrasion resistance for running through trees
UV & Weather resistant for use on the seacoast or in other harsh environments subjected to acid rain, high wind, or high snow and ice loads.

Single band 20 meter dipole
My 2nd NI4L antenna, the other being a multi-band OCF dipole. Both work great & well built with very low SWR across the band. Recommend his products highly.
20M Half wave antenna
Very pleased with the antenna. Construction seems to be solid and well built. This is my Third antenna from ni4l.com and all are doing well. support has been great and very prompt. Thanks Chris.
Great Antenna. Works flawlessly
Can't say enough good things about this antenna.
Excellent quality. I'm very pleased with the antenna and the reception I'm getting. I would buy from NI4L again.
