WebBoth are square. The 160 Meter loop is fed with Open Wire Line and the 80 Meter antenna uses 450 Ohm Ladder line. The ladder line is the typical poly insulated wire with punch outs. The open wire line is home made. Both antennas serve me well. I use a Johnson Matchbox with the 80 Meter antenna and a Palstar BT-1500 with the 160 Loop. WebHF antennas come in a variety of shapes and sizes. They can range from a simple wire thrown into a tree or a complex quad beam on a 40' crank-up tower.
