Hello All Recently I purchased a tuned passive magnetic antenna for receiption of utility stations in the 70-150 kHz range. Initial messurements on it showed, that sensitivity was only slightly lower
How do I form a low loss coil for 137 kHz using mentioned 2mm annealed copper wire? Hi, Gamal, Do you have access to teh ARRL Antenna Handbook, 18th edition (1998), page 5-6 to 5-8? If not, e-mail m
