How to get the most out of an attic antenna for 40-10 meter operation using available materials with a counterpoise system. Many ideas are included for different types of attic situations using wire, autotuner, coax, insulators, and ground radials. The specific inverted L system in use is shown with detailed dimensions. A 10 meter section is isolated with a trap from an old tri band beam and is resonant. The remainder of the bands are non resonant and tuned with an autotuner at the base for operation on 40-30-20-17-15-12-10 meter amateur radio hambands. The video explains the effects of wood rafters, asphalt shingles, low proximity to the ground, antenna wire diameter, and typical home in...
