40_m_LOOP_ANTENNA

A cliff-dweller's dream, this 40-m loop can get apartment-based hams on the air. It also makes a great receiving antenna. The matching transformer, T1, is wound on T50-2 toroid core. The primary consists of 4 turns of 18-gauge enameled copper wire, and the secondary consists of 12 turns of 20-gauge enameled copper wire. Close-wind the secondary and the primary, and make sure that the two windings do not overlap.
