• Trapped Dipole for 12 and 17 Meters - A small sized and very cheap antenna project that allow you to work on WARC bands with a total gain very close to the dipole in both bands. On 12 meters is a normal dipole, while on 17 is a trapped dipole. Article in Italia

• Antennas for 160m - The best results work when you have an antenna with a large vertical component. It is difficult to get a horizontal antenna (dipole) high enough to be an effective antenna on 160. However, there are several easy things you can do with your present antenna to initially get on the best amateur radio band

• 40m Vertical End-Fed Antenna - A quarter wave vertical end-fed antenna for the 40 meters band. As all vertical antennas, also this aerial requires a good earthing system. In this project the ground is composed by twelve 4, wires buried in the lawn by using a spade to create a slit to drop the wire into.
