An Improved Double Extended Zepp By Rudy Severns, N6LF. 32857 Fox Lane PO Box 589. Cottage Grove, OR 97424. This article was orinally published in the ARRL Antenna Compendium Vol. 4 1995. T. he sunspot cycle is headed down and the low bands are coming to life for DXing. The next several years will N6LF revisits the classic Double be the time to make those low-band contacts for DXCC. As always, the key to low-band Extended Zepp to improve pattern and SWR bandwidth. He also offers operation is a good antenna. Unfortunately for 7 MHz and down, good antennas don't come in a box ready to assemble. Every lo- cation will have a unique set of limitations and opportunities.

The “bulging out” of the current in the opposite direction near the center of the antenna is responsible for the sidelobes seen in Fig 1. Fig 3—Schematic for modified N6LF DEZepp, with new current distribution.
