This is post #1066 in a continuing series of "Simple Ham Radio Antennas." The heart of this all band HF end fed halfwave antenna (160 meters to 6 meters) is the 9:1 unun transformer used to match the high impedance of the wire antenna to the low impedance of the HF transceiver.  The 9:1 unun is made from 20 gauge wire wound on a torroidal coil. You can order the full unun through eBay under "nelson_antennas."  The antenna can be configured as a vertical, sloper, or inverted vee. Adding a counterpoise system will improve efficiency and reduce ground losses.
