Adding 80 metres to a 40 metre dipole. Post 1815.

If you live on a small urban lot, erecting a full-sized 80 meter dipole antenna will present a difficult challenge.  According to Australian ham Peter Parker (VK3YE), a simple 40 meter dipole antenna can be modified to work at 3.5 MHz (80 meters) by adding end-loading coils.  Although the "transformed" antenna won't be as efficient as a full-length 80 meter dipole, it will get you on the air with a somewhat narrower bandwidth.  Peter's adaptation comes from an original design by VK5AH.
