im working on a big coil for looking for meteorites. it osc is 125k . checking (air test) i notice a frequency change at about 5ft with a plate. now the loop is about 4 1/2 feet across. im going to make a second osc at 125khz and combine the to freqencies. anyone got any suggestions for improving it. i here the higher frequencies get better penetration into the ground. true/false?
