Simple Ham Radio Antennas

Thanks to Australian radio amateur Peter Parker (VK3YE) for this simple, effective way to build a two-band trap dipole antenna (7 MHz and 14 MHz). If you design the antenna properly, it should give your excellent performance.

This video describes a trap dipole for 7 and 14 MHz with emphasis on the 1:1 current balun and 14 MHz trap. Adding 80 metres: Loading coils can be added to provide 3.5 MHz capability with very little extra room required. My loading coils used 85 turns of 2mm (od) thin insulated wire closewound on a 55mm diameter pipe. There will be some interaction between the loading coil and the 7 MHz element. Add extra wire to bring it back in...
