My Vertical Loop Antenna for 80 Meters. Post#1181.

Now that propagation is favoring the lower HF bands (160, 80, and 40 meters), you may want to design and build an antenna specifically designed for one of those bands.  In this video, "Lockemeister" chose a full-wavelength vertical loop for 80 meters, getting the best SWR on 3.913 MHz.  He can cover most of the band with his MFJ-Versa II antenna "tuner."  Fortunately, Lockemeister had a sufficiently large yard to contain this antenna.  A full-wavelength loop makes an excellent NVIS (near vertical incident skywave) antenna capable of reaching out to approximately 300 miles/486 km on 80 meters--perfect for working local, state, and regional contacts.  Multiband coverage is possible by feeding the antenna with 450 ohm ladder line, 300 ohm television twin lead, or 600 ohm balanced line in conjunction with a 4:1 balun and an antenna "tuner."
