According to Peter Parker (VK3YE), "A trap dipole is a good choice if you only want operation on two or three bands and don't want to adjust an antenna coupler to change between them." In this well-produced, easily understandable tutorial, Peter takes us step-by-step through the design, construction, and use of a trap dipole for the 40 meter (7 MHz) and 20 meter (14 MHz) amateur radio bands. Of course, you could design this antenna for other bands, such as 80/40 meters and 15/10 meters. Other than winding some coils, the antenna is simple, effective, and fairly inexpensive. This antenna would make a good weekend project.
