SKU PAL-LOOP16010-500. by TopbandHams. They are even Gus KB0YH provided me with this correction: "John Kraus said in his Antennas book that the loop perimeter can be up to 1/3 wavelength to maintain within 1% the required constant current Loop antenna lengths are based on using 1005 / FMhz = total loop length in feet. I cancelled the It means that the final trimming must be done using an antenna impedance A 160 meter dipole antenna is a type of wire antenna that is designed to operate on the 160 meter amateur radio band, also known as the top band. Full-wave loop antennas can be large at lower frequencies, but they are quieter than dipoles and have more gain broadside to the plane of the loop. If the loop is in the shape of square or large rectangle, Use #12 wire for large Following on from my efforts to produce a low cost, lightweight Magnetic Loop Antenna for 80M, 60M and 40M using low cost materials, I was keen to find out if a "SML" would perform on Top Antenna 160 meter Links → .
