Dual-Band Loop Antenna For 80-160 M Circuit


Posted on Jul 9, 2012

This antenna might help to reduce power-line noise. A plastic hula hoop or conduit 3 feet in diameter, covered with aluminum foil as a shield is used for LI and L2. LI is two turns and L2 is one turn, threaded through the loop. SI selects 160- or 80-m operation. Ql and Q2 form a preamplifier for the loop antenna.
